feat: regenerate paymentId when amount is updated #572
Conversation
WalkthroughReplaces client-side payment-id generation with server-created paymentId via new createPayment; adds convertedCurrencyObj state and converted-amount flows; threads paymentId and conversion props through PayButton → PaymentDialog → WidgetContainer → Widget; adds amount-editing UI and tests; adds react-number-format dependency.

226-275: Fix the useEffect dependency array and add missing cleanup.The effect on lines 226-275 has two issues:
Stale closure risk: Missing critical dependencies (
to,apiBaseUrl,wsBaseUrl,currency,price,paymentId, etc.). If these values change while the dialog is open, the WebSocket will be set up with stale values.Incomplete cleanup: The cleanup function only disconnects
altpaymentSocket(lines 269-271) but never disconnectstxsSocket, creating a potential memory leak.Add all used values to the dependency array and ensure
txsSocketis properly disconnected in the cleanup function.

Critical: Effect guard prevents paymentId regeneration on amount changes.
This effect has several issues that prevent it from fulfilling the PR's objective to "regenerate paymentId when amount is updated":
-
Lines 564-569: The guard
if (fetchingPaymentId !== undefined || paymentId !== undefined) returncombined with settingfetchingPaymentIdtotruemeans this effect will never run again after the first execution, even when the amount changes. -
Line 603: The dependency array includes
fetchingPaymentId, which this effect sets, creating potential for unexpected re-runs or infinite loops. -
Lines 592-599: The else branch redundantly sets
paymentIdto its existing value. -
Missing dependency: The effect doesn't track
convertedCurrencyObjchanges properly to trigger regeneration.
Consider this revised implementation:
useEffect(() => {
- if (
- fetchingPaymentId !== undefined ||
- paymentId !== undefined
- ) {
+ // Skip if disabled or already fetching
+ if (disablePaymentId || fetchingPaymentId) {
return
}
- if (setFetchingPaymentId) {
- setFetchingPaymentId(true)
- }
+
const initializePaymentId = async () => {
- if (paymentId === undefined && !disablePaymentId) {
- if (to) {
- try {
+ if (to) {
+ try {
+ if (setFetchingPaymentId) {
+ setFetchingPaymentId(true);
+ }
+
const amountToUse =
(isFiat(currency) || randomSatoshis) && convertedCurrencyObj
? convertedCurrencyObj.float
: props.amount
const responsePaymentId = await createPayment(amountToUse || undefined, to, apiBaseUrl);
if (setPaymentId) {
setPaymentId(responsePaymentId);
}
- if (setFetchingPaymentId) {
- setFetchingPaymentId(false);
- }
- } catch (error) {
- console.error('Error creating payment ID:', error);
- }
+ } catch (error) {
+ console.error('Error creating payment ID:', error);
+ } finally {
+ if (setFetchingPaymentId) {

}
- } else {
- if (setPaymentId) {
- setPaymentId(paymentId);
- }
- if (setFetchingPaymentId) {
- setFetchingPaymentId(false);
- }
}
};
initializePaymentId();
- }, [paymentId, disablePaymentId, props.amount, to, apiBaseUrl, setPaymentId, setFetchingPaymentId, fetchingPaymentId, convertedCurrencyObj]);
+ }, [disablePaymentId, props.amount, convertedCurrencyObj, to, apiBaseUrl, setPaymentId, setFetchingPaymentId, currency, randomSatoshis, isFiat]);Additionally, ensure that paymentId is cleared when convertedCurrencyObj or props.amount changes to trigger regeneration.

In react/lib/components/Widget/Widget.tsx around lines 563 to 603, the current
effect short-circuits future runs by returning when paymentId or
fetchingPaymentId are defined, includes fetchingPaymentId in the dependency
array, and redundantly re-sets paymentId; change the logic so the effect watches
props.amount and convertedCurrencyObj (add both to deps), remove
fetchingPaymentId from the deps, and do NOT return early just because paymentId
exists — instead only skip if a fetch is already in progress (check a
local/closure ref or the boolean setter state value), clear paymentId when
props.amount or convertedCurrencyObj change to force regeneration, set fetching
flag true before calling createPayment and false in finally, only call
setPaymentId when a new id is returned (avoid setting the same value), and
handle errors in catch (logging and ensuring fetching flag is reset).

Newly generated paymentIds, when changing amount, are being sent for the same amount.
Might have to do with this rabbitAI comment:
https://github.com/PayButton/paybutton/pull/572/files#r2496572271
Also the editable widgets in http://localhost:10001/ are showing Send any amount of XEC instead of the defined 1000.69 XEC amount.

convertedCurrencyObjorprops.amountchanges to trigger regeneration, which is the core PR objective.The PR states: "Regenerate paymentId when amount changes in editable mode." This effect does not implement that behavior.
Apply this fix to enable regeneration:

updateConvertedCurrencyObjhelper (lines 259-267) already clearspaymentIdwhen the converted currency changes, which should trigger this effect to regenerate the ID.
🧹 Nitpick comments (2)
react/lib/components/Widget/Widget.tsx (2)
259-267: Consider renaming for clarity.The function clears payment-related state when the converted currency changes, which is correct for triggering paymentId regeneration. However, the name
updateConvertedCurrencyObjsuggests it updates the currency object itself, when it actually clears payment state after setting the currency object.Consider a more descriptive name:
- const updateConvertedCurrencyObj = useCallback((convertedObj: CurrencyObject | null) => { + const setConvertedCurrencyObjAndClearPayment = useCallback((convertedObj: CurrencyObject | null) => { setConvertedCurrencyObj(convertedObj); if(setPaymentId){ setPaymentId(undefined); } if(setFetchingPaymentId){ setFetchingPaymentId(undefined); } }, [setConvertedCurrencyObj, setPaymentId, setFetchingPaymentId]);
643-673: Consider adding convertedCurrencyObj to dependencies.Lines 645-646 use
convertedCurrencyObjas a fallback when calculating the converted amount. While the current logic should keepconvertedCurrencyObjin sync (via the effect at lines 604-630), this effect doesn't listconvertedCurrencyObjin its dependency array (line 673).Add
convertedCurrencyObjto the dependency array to ensure the URL regenerates when the converted currency changes:- }, [to, thisCurrencyObject, price, thisAmount, opReturn, hasPrice, isCashtabAvailable]) + }, [to, thisCurrencyObject, price, thisAmount, opReturn, hasPrice, isCashtabAvailable, convertedCurrencyObj])This ensures that if
convertedCurrencyObjupdates independently (e.g., from a parent component), the URL will be recalculated.

168-192: Critical: PaymentId is not regenerated when amount changes.Line 178 checks
!paymentIdbefore callinggetPaymentId, which prevents regeneration when the amount changes if a paymentId already exists. This directly contradicts the PR objective: "regenerate paymentId when amount is updated."Scenario:
- User opens payment dialog with amount=100 → paymentId is created
- User changes amount to 200
- User clicks button → Line 178 evaluates to false (paymentId exists)
- getPaymentId is NOT called → old paymentId persists with wrong amount
To fix this, remove the
!paymentIdcheck and add a useEffect to clear paymentId when amount/convertedAmount changes:- if (!disablePaymentId && !paymentId) { + if (!disablePaymentId) { await getPaymentId(currency, Number(amount), convertedAmount, to) }Additionally, add this effect to clear paymentId when amount changes:

Conversion guards prevent recalculation when amount changes.
Lines 314 and 325 use !convertedCurrencyObj guards that prevent conversion recalculation when the amount changes. Once convertedCurrencyObj is set, these blocks never execute again, even if amount, price, or randomSatoshis change.
Consider removing these guards or adding amount/price to trigger recalculation:
useEffect(() => {
if (currencyObj && isFiat(currency) && price) {
- if(!convertedCurrencyObj) {
const addressType: Currency = getCurrencyTypeFromAddress(to);
const convertedObj = getCurrencyObject(
currencyObj.float / price,
addressType,
randomSatoshis,
);
setCryptoAmount(convertedObj.string);
setConvertedAmount(convertedObj.float);
setConvertedCurrencyObj(convertedObj);
- }

const convertedObj = getCurrencyObject(
amount as number,
addressType,

setCryptoAmount(convertedObj.string);
setConvertedAmount(convertedObj.float);

In react/lib/components/PayButton/PayButton.tsx around lines 312 to 337, the
current guards using !convertedCurrencyObj (lines ~314 and ~325) stop
recalculation once convertedCurrencyObj is set, so changes to amount, price or

(or replace them with explicit comparisons against current convertedCurrencyObj
values) so the effect recalculates and calls getCurrencyObject whenever its

and keep setting cryptoAmount, convertedAmount and convertedCurrencyObj
accordingly.

Critical: Add error handling and response validation.
The function lacks try-catch wrapping and doesn't validate that data.paymentId exists before returning it. This can cause:
- Network/request failures: If axios.post throws (network error, timeout, etc.), the error propagates unhandled to the caller.
- Missing paymentId: If status is 200 but data.paymentId is null/undefined, the function returns undefined without logging or throwing, silently failing.
Apply this fix:
export const createPayment = async (
amount: string | number | undefined,
address: string,
rootUrl = config.apiBaseUrl,
): Promise<string | undefined> => {
+ try {
const { data, status } = await axios.post(
`${rootUrl}/api/payments/paymentId`,
{ amount, address }
);
if (status === 200) {
+ if (!data.paymentId) {
+ throw new Error('Payment ID missing in response');
+ }
return data.paymentId;
}
throw new Error(`Failed to generate payment ID. Status: ${status}, Response: ${JSON.stringify(data)}`);
+ } catch (error) {
+ if (axios.isAxiosError(error)) {
+ throw new Error(`Failed to generate payment ID: ${error.message}`);
+ }
+ throw error;
+ }

In react/lib/util/api-client.ts around lines 92 to 107, wrap the axios.post call
in a try-catch and validate the response before returning: catch any
axios/network errors and rethrow (or throw a new Error) with the
status/response/error details, check that status === 200 and that data &&
data.paymentId is a non-empty string (otherwise throw an informative Error
including the response body), and ensure the function consistently throws on
failures instead of returning undefined so callers always get a resolved
paymentId or a clear exception.

Minor: Input constraint mismatch with validation logic.
The min: 1 constraint on the donation rate input (line 1244) differs from the validation logic at lines 268-271, which allows 0. Users can disable donation by toggling the heart icon (setting rate to 0), but if they type "0" directly, they may encounter browser validation messages.
This is a minor UX inconsistency rather than a bug—the clampDonationRate function correctly handles 0.
Consider either:
- Setting
min: 0to match validation, or - Hiding the input entirely when
donationEnabledis false (already shows/hides based on toggle)
The current behavior is acceptable since the toggle is the primary UI, but consistent constraints improve clarity.

In react/lib/components/Widget/Widget.tsx around lines 1243-1244, the donation
rate input sets inputProps.min = 1 which contradicts validation
(clampDonationRate permits 0); update the component to make constraints
consistent by changing the input min to 0 to allow typing 0, or alternatively
conditionally hide/remove the numeric input when donationEnabled is false so
users can only use the toggle to disable donations—pick one approach and apply
it consistently so browser validation and internal validation align.

495-501: Editable amount UX viaNumericFormatanddraftAmountlooks solidThe new draft‑amount flow is well‑structured:
draftAmountis derived fromthisCurrencyObject.stringviastripFormatting, so the input always reflects the formatted value.NumericFormatkeeps user input normalized and adds thousand separators without polluting underlying state.applyDraftAmountvalidates, converts to a numeric value, then callsupdateAmountto drive the same pipeline as programmatic changes.- The ✓ button is disabled when the draft is invalid or equal to the current amount (
isDraftValid/isSameAmount), which avoids redundant work.Overall this is a nice improvement for editable mode; I don’t see correctness issues here.

921-943: Donation URL query string uses twoamountparams – confirm receiver behaviorIn
resolveUrl, when applying a donation you now build:thisUrl += `?amount=${amount}` thisUrl += `&addr=${donationAddress}&amount=${thisDonationAmount.toFixed(decimals)}`So the final URI contains two
amountquery params (amount=<base>&addr=...&amount=<donation>). Depending on how wallets / your backend parse this, either:
- Only the last
amountis honored, or- A non‑standard interpretation is used (e.g., multi‑output semantics).
If this dual‑
amountformat is an intentional, existing convention for PayButton/Cashtab, then this change is fine (the only new behavior is decimal rounding). If not, this could accidentally override the main payment amount or ignore the donation.I’d recommend:
- Verifying with the target wallet(s) exactly how multiple
amountparams are handled.- If needed, switching the donation to distinct keys (e.g.,
&donation_addr=...&donation_amount=...) and adjusting the consumer accordingly.

Conversion effect missing key dependencies and uses price without being in deps
The useEffect that recomputes thisCurrencyObject and convertedCurrencyObj after amount edits:
useEffect(() => {
// ...
if (userEditedAmount !== undefined && thisAmount && thisAddressType) {
const obj = getCurrencyObject(+thisAmount, currency, false);
// ...
const convertedAmount = obj.float / price
const convertedObj = price
? getCurrencyObject(convertedAmount, thisAddressType, randomSatoshis)
: null;
updateConvertedCurrencyObj(convertedObj)
} else if (thisAmount && thisAddressType) {
const obj = getCurrencyObject(cleanAmount, currency, randomSatoshis);
setThisCurrencyObject(obj);
if(!isFiat(currency)) {
updateConvertedCurrencyObj(obj);
}
// ...
}
}, [thisAmount, currency, userEditedAmount])But inside it you also depend on price, thisAddressType, randomSatoshis, updateConvertedCurrencyObj, and props.setCurrencyObject. With the current dependency array, changes to any of those will not recompute conversions, which can leave convertedCurrencyObj and downstream paymentId logic stale.
Recommend expanding the deps and avoiding the divide‑by‑zero when price is falsy:
- useEffect(() => {
+ useEffect(() => {
// ...
- if (userEditedAmount !== undefined && thisAmount && thisAddressType) {
+ if (userEditedAmount !== undefined && thisAmount && thisAddressType) {
const obj = getCurrencyObject(+thisAmount, currency, false);
setThisCurrencyObject(obj);
if (props.setCurrencyObject) {
props.setCurrencyObject(obj);
}
- const convertedAmount = obj.float / price
- const convertedObj = price
- ? getCurrencyObject(
- convertedAmount,
- thisAddressType,
- randomSatoshis,
- )
- : null;
+ let convertedObj: CurrencyObject | null = null;
+ if (price) {
+ const convertedAmount = obj.float / price;
+ convertedObj = getCurrencyObject(
+ convertedAmount,
+ thisAddressType,
+ randomSatoshis,
+ );
+ }
updateConvertedCurrencyObj(convertedObj)
} else if (thisAmount && thisAddressType) {
// ...
}
- }, [thisAmount, currency, userEditedAmount])
+ }, [thisAmount, currency, userEditedAmount, price, thisAddressType, randomSatoshis, updateConvertedCurrencyObj, props.setCurrencyObject]);This keeps conversions and convertedCurrencyObj aligned with all inputs.

Key type mismatch in CURRENCY_TYPES_MAP
CRYPTO_CURRENCIES is ['BCH', 'XEC'], but CURRENCY_TYPES_MAP uses keys bitcoincash and ecash while being typed as Record<typeof CRYPTO_CURRENCIES[number], string>. This is inconsistent with the declared key type and will confuse TypeScript (and tools) even if it happens to work at runtime.
Since createPayment indexes this map with the BIP21-style prefix from getAddressPrefix(address), it’s clearer and safer to type this map explicitly to those prefixes and to known decimal keys:
-export const CURRENCY_TYPES_MAP: Record<typeof CRYPTO_CURRENCIES[number], string> = {
- bitcoincash: 'BCH',
- ecash: 'XEC'
-};
+export const CURRENCY_TYPES_MAP: Record<'bitcoincash' | 'ecash', keyof typeof DECIMALS> = {
+ bitcoincash: 'BCH',
+ ecash: 'XEC',
+};This keeps the runtime behavior the same while aligning the type with actual keys and DECIMALS usage.

convertedCurrencyObjis not in the dependency array, so if a parent or another effect updatesconvertedCurrencyObjwithout changingthisCurrencyObjectorprice, the visible text and QR URL won’t update.Recommend adding it:

113-114: Amount-basedpaymentIdregeneration logic is aligned with PR goal; consider small hardening against stale async results.The new

ThelastPaymentAmountref is a good guard against redundant calls for the same amount.One improvement to avoid a rare race where a slower

Guard widget-side createPayment when parent controls paymentId to avoid redundant server calls.
This effect now calls createPayment whenever effectiveAmount changes, regardless of whether a parent has already provided a paymentId via props. In the common PaymentDialog → WidgetContainer → Widget flow, PayButton is already generating a paymentId and passing it down, so this effect will still POST to /api/payments/paymentId for each amount change but then write the result only into the internal state that’s ignored when paymentId prop is non‑undefined. That means:
- Extra, unused payment IDs are created on the server for the same address/amount.
- Network/API usage is higher than necessary without UI benefit.
You can keep this effect as the fallback for “standalone widget” usage by short‑circuiting when paymentId is already defined:
useEffect(() => {
if (
isChild ||
disablePaymentId ||
+ paymentId !== undefined ||
setPaymentId === undefined ||
to === ''
) {
return;
}
@@
- void initializePaymentId();
+ void initializePaymentId();
}, [
isChild,
disablePaymentId,
+ paymentId,
to,
currency,
convertedCryptoAmount,
convertedCurrencyObj,
thisAmount,
apiBaseUrl,
setPaymentId,
- lastEffectiveAmountRef,
]);lastEffectiveAmountRef doesn’t need to be in the dependency array since useRef values are stable.
🤖 Prompt for AI Agents
In react/lib/components/Widget/Widget.tsx around lines 585 to 651, the effect
unconditionally calls createPayment when effectiveAmount changes even if a
parent supplied paymentId, causing redundant server calls; modify the effect to
return early when the paymentId prop is defined (i.e., guard the effect with if
(paymentId !== undefined) return) so the widget only creates a paymentId as a
fallback, and remove lastEffectiveAmountRef from the dependency array since refs
are stable.

352-375: Conversion guards prevent recalculation when amount or price changes.Lines 354 and 364 use

173-210: UnusedpaymentIdin dependency array causes unnecessary effect runs.Line 210 includes

585-650: Payment ID effect is missing guard for already-setpaymentIdprop.When a parent component passes
paymentIdas a prop (e.g., PayButton → PaymentDialog → WidgetContainer → Widget), this effect will still callcreatePaymentbecause there's no check forpaymentId !== undefined. This creates redundant server-side payment IDs.The

1-50: Test scaffolding and mocks look correct.The mock for
PaymentDialogprovides simulated controls for amount changes and conversion object updates. ThecreatePaymentmock returns a consistent ID. ThebeforeEachwithjest.clearAllMocks()ensures test isolation.
52-91: LGTM on basic click handlers tests.These tests correctly verify the
onOpencallback behavior for both crypto (XEC) and fiat (USD) paths, with appropriate async handling for the price fetching flow.
117-146: Verify fiat path timing: clickingmock-set-convertedbeforedonatemay not match real user flow.The test clicks
mock-set-convertedbefore opening the dialog (line 129-131, then line 133). In the real flow, the dialog opens first and then conversion happens inside. This sequencing might not accurately represent production behavior.Consider whether setting
convertedCurrencyObjbefore the dialog opens reflects actual usage, or if the test should open the dialog first and then simulate conversion.
184-216: Amount change flow test is well-structured.The test correctly verifies that changing the amount via
mock-change-amounttriggers a secondcreatePaymentcall with the incremented value.
256-291: Fiat preference test may have fragile timing.The test at lines 282-290 asserts that changing the base amount while
convertedCurrencyObjis set does NOT trigger additionalcreatePaymentcalls. However, the mock'ssetAmountcallback at lines 20-22 only updates a numericprevvalue; it doesn't clear or updateconvertedCurrencyObj. Verify this matches the actual component's behavior where base amount changes are ignored whenconvertedCurrencyObjis present.react/lib/components/PayButton/PayButton.tsx (3)
113-125: State additions for payment flow look correct.The new
convertedCurrencyObjandpaymentIdstate variables are properly initialized and align with the PR objective to track converted amounts and regenerate payment IDs.
145-170:getPaymentIdcorrectly computes the amount to use for fiat/crypto paths.The logic at lines 155-158 properly prefers
convertedCurrencyObj.floatfor fiat currencies or whenrandomSatoshisis enabled, falling back to the raw amount otherwise.
451-453: Props correctly forwarded toPaymentDialog.The new
convertedCurrencyObjandsetConvertedCurrencyObjprops are properly passed, enabling the dialog to participate in the conversion flow.react/lib/components/Widget/Widget.tsx (6)
15-15: NumericFormat import aligns with draft amount workflow.The
react-number-formatlibrary provides formatted number input with thousand separators and decimal control, appropriate for the editable amount field.
54-55:createPaymentimport enables standalone Widget to generate payment IDs.This allows the Widget to function independently when not used as a child of PayButton/PaymentDialog.
99-117: New props expand Widget's public API surface appropriately.The addition of
convertedCurrencyObj,setConvertedCurrencyObj, andsetPaymentIdenables proper coordination with parent components for payment ID regeneration when amounts change.
179-188: Draft amount state and loading flags are well-designed.The
draftAmountstate separates user input from committed values, preventing partial edits from triggering API calls. TheisWaitingForPaymentIdflag correctly blocks QR display until payment ID is ready for child widgets.
988-1016: Draft amount helpers are concise and correct.
stripFormattingproperly removes thousand separators and trailing zeros.applyDraftAmountvalidates before committing.isDraftValidandisSameAmountprovide clean conditional checks.
1188-1231: NumericFormat integration is well-implemented.The component correctly:
- Uses
onValueChangeto get the unformatted value- Handles Enter key to apply changes
- Shows/hides the Confirm button based on validation state
- Limits decimal places to 8 (matching crypto precision)

1-62: Well-structured test setup with comprehensive mocks.The mock configuration for the
utilmodule andapi-clientproperly isolates the Widget component for testing. The approach of importing the mocked modules afterjest.mock()calls is correct for Jest's hoisting behavior.
64-245: Good coverage for paymentId lifecycle.Tests properly verify:
- Initial creation on standalone render
- Guards for
isChildanddisablePaymentId- Regeneration on amount changes
- Deduplication for same effective values
This aligns well with the PR objective to "regenerate paymentId when amount is updated."

14-45: Effective mock strategy for PaymentDialog.The mock dialog with
mock-change-amountandmock-set-convertedbuttons provides a clean way to simulate dialog-driven state changes without testing the actual dialog implementation. This keeps the tests focused on PayButton's payment ID logic.
184-216: LGTM!This test directly validates the PR objective—when the amount changes while the dialog is open, a new payment ID is created with the updated amount.
218-254: LGTM!The test validates that each distinct amount triggers exactly one
createPaymentcall, ensuring no redundant API calls and proper deduplication.
256-291: LGTM!This test confirms that for fiat currencies, the
convertedCurrencyObjamount takes precedence over base amount changes, preventing unnecessary payment ID regeneration when only the display amount changes.

</function_calls>Based on my attempts to examine the file, let me now provide a final analysis based on what I've been able to verify. Let me make one more focused attempt at understanding the core issue:
<function_calls>
#!/bin/bashLook for Dialog mock - how it handles isOpen

</function_calls><function_calls>
#!/bin/bashTry simpler rg queries

</function_calls><function_calls>
#!/bin/bashCheck what we have in the test more directly
rg "mock-set-converted|donate" react/lib/tests/components/PayButton.test.tsx -n -C 3
</function_calls>Let me now synthesize what I know and provide the final analysis. Based on the review comment and my investigation:
Key Facts Established:
- The test file exists at:
react/lib/tests/components/PayButton.test.tsx- The test at lines 117-146 tests fiat currency conversion
- The test sequence is: click mock-set-converted → click donate → verify payment
The Core Concern:
The review suggests that in a real user flow, the conversion would happen AFTER the dialog opens (when currency conversion data becomes available), but the test appears to set it BEFORE clicking donate.Verification Challenge:
I cannot access the PayButton component implementation directly, and the test uses mocks for Dialog and CurrencyConverter components. This means:
- The mock may render children unconditionally (not respecting isOpen)
- OR the test may not accurately reflect the real flow
- OR the test structure is intentionally simplified for testing
Since I cannot definitively verify the actual PayButton implementation behavior, I should provide a review comment that acknowledges this uncertainty while still capturing the original concern.
Verify whether the dialog actually renders all children unconditionally in the mocks, or if the test sequence incorrectly assumes the converted amount is available before the dialog opens.
The test clicks
mock-set-converted(lines 129-131) before clicking the donate button (line 133). This suggests the mock Dialog is rendering its children regardless of theisOpenstate. Verify in the Dialog mock whether children render conditionally or unconditionally, and whether this matches the actual component behavior where conversion data would only be available after the dialog opens.react/lib/components/Widget/Widget.tsx (3)
988-1024: LGTM!The draft amount workflow is well-structured with proper validation (
isDraftValid) and duplicate prevention (isSameAmount). ThestripFormattingfunction correctly removes thousand separators and trailing zeros.
1186-1233: Good integration of NumericFormat with MUI TextField.The implementation correctly:
- Uses
onValueChangeto get the raw numeric value- Limits decimal precision to 8 places
- Supports both Enter key and button confirmation
- Shows the Confirm button only when the draft is valid and different
183-188: LGTM!The
isWaitingForPaymentIdflag correctly blocks QR display for child widgets until the parent provides a payment ID. TheqrLoadingcomposition elegantly combines both loading states.

Effect dependencies incomplete—conversions may use stale values.
This effect references price, thisAddressType, randomSatoshis, updateConvertedCurrencyObj, and props.setCurrencyObject but only includes [thisAmount, currency, userEditedAmount] in dependencies. When price or address type changes without amount changing, the converted values will be stale.

In react/lib/components/Widget/Widget.tsx around lines 698 to 725, the effect
lists only [thisAmount, currency, userEditedAmount] but reads price,
thisAddressType, randomSatoshis, updateConvertedCurrencyObj and
props.setCurrencyObject so conversions can become stale; add price,
thisAddressType, randomSatoshis, updateConvertedCurrencyObj, and
props.setCurrencyObject to the dependency array and, inside the branch that
computes convertedAmount, guard the division by zero by checking price
truthiness before dividing (return or set convertedObj to null when price is
falsy) so you never divide by zero and converted state updates when any input
changes.
