🟢 green_dot

A powerful TypeScript nodeJs framework for building DX friendly, secure and front-end / back-end type-safe backend services with MongoDB integration (other DBs coming soon) and SDK generation

Official Documentation QuickStart Guide

Features

🧭 Back/Front Type-safe API route declarations, shared models
📐 Secure model definitions with validation and routes exposed automatically via configuration
🪪 Built-in DX friendly unified security and access control
🔌 Powerful plugin system with Managed Login, ApiKey Login, and Secure Authentication (2FA, biometric authentication and pinCode) (BETA) 🪄 File generation from templates to generate project, database, app, model...so you get up and running in no time 🗃️ MongoDB integration with type safety (others database drivers to come)
👨‍💻 DX and intellisense friendly
🏗️ Generate it's own SDK to use in frontend, get your backend data without await or useEffect: (Eg: const result = $.useQuery.myApiRoute())
⚡ Fully cached in frontend via TanStack Query
📦 VSCode / Cursor Plugin

Quick Start

1. Generate a project with npx green_dot generate in a blank folder
2. Generate your first model with npx green_dot generate => and choose 'Model'
3. Configure model security in the .dao.ts generated file
4. Generate your first service (api route) with npx green_dot generate => and choose 'Service'

IDE Integration

1. Hover any green_dot props or function to see the documentation in your IDE
2. Type gd_ in any ts file to see all green_dot snippets to use to improve productivity
3. Install VSCode / Cursor extension from the IDE extension tab or by downloading it here

Note: you can create mutiple app and dbs with the npx green_dot generate command

Helpers

• getMainConfig() => get your main config where yuo set allRoles, allPermissions
• getActiveAppConfig(), getActiveDbConfig() => get respective actual db/app config

API Service example

• run npx green_dot generate and select > Api Service

export const checkUserExists = svc({
    // Access level
    for: ['customRole', { role; 'user', hasValidatedEmail: true }],
    // Type-safe input validation
    input: {
        email: _.email().required(),
        user: _.model('myDbName', 'user'), // ref to app models
    },
    // Type-safe output
    output: _.boolean(),
    // optional security features
    rateLimiter: '10/min',
    ...
    async main(ctx, { email }) {
        const nbUsers = await db.user.count(ctx.GM, { email })
        return !!nbUsers
    },
})

Api Service Features

• Everything is typed / Autocomplete friendly
• Nothing else to do, route is declared automatically based on the name of the exported constant
• Fine tuning on security features (roles, permissions...)
• Route will be available in frontend via the generated SDK (const userExists = $.checkUserExists() // type boolean)
• A Swagger documentation will be generated for the route

See documentation (will come soon) for more details.

Model and DB Security

To create an api service:

• run npx green_dot generate and select > Database Model
• this will generate ./myModel.model.ts and ./myModel.dao.ts files for declaring model and DAO (data access object, a security configuration for your model)

Models

const model = _.mongoModel(
  // Automatic timestamp fields
  ['creationDate', 'updateDate'], 
  {
      name: _.string().required(),
      admin: _.ref('user').required(),
      companyIdenfier: _.string().required().unique(),
      address: {
          street: _.string().required(),
          zipCode: _.string().required(),
          city: _.string().required(),
          country: _.string().required(),
      },
})

DAO (Data Access Object)

Configure data access with security and type safety:

// user.dao.ts
const dao = {
    type: 'mongo',
    // The expose config will automatically create routes for given
    // permissions and config
    expose: [{
        // Here user and admin both can update or getOne for your model
        for: ['user', 'admin'],
        expose: ['getOne', 'update'],
    }, {
        // Here only admin can getAll
        for: ['admin'],
        expose: ['getAll'],
    }],
    // Filter is another powerful security feature, it allow to add filter
    // depending on the connected user
    filter: [{
        on: ['read', 'write'], // for all methods
        for: 'ALL', // for all perms
        filter: (ctx, filter) => {
            if (ctx.role === 'admin') return
            // if !admin we constrain the filter to be the userId
            // so we make sure the user can only acess his own user!
            else filter._id = ctx._id
        }
    }],
    // Mask allow to mask fields of a model depending on user permissions 
    // and methods (read, update, create...)
    mask: [{
        on: ['read'],
        // for everyone, we mask password field on read
        mask: () => ({
            password: true,
        }),
    }, {
        // only admin can see user.stats
        on: ['read'],
        notFor: 'admin',
        mask: () => ({
            stats: true
        }),
    }],
    populate: [
        // we can always populate a field if needed
        'company',
    ],
}
