…dom`](https://github.com/WebReflection/linkedom) (SSR). - [`linkedom`](https://github.com/WebReflection/linkedom) is being used https://github.com/matrix-org/matrix-public-archive to server-side render (SSR) Hydrogen (`hydrogen-view-sdk`) - This is being fixed by using a explicit HTML wrapper boilerplate with `DOMParser` to get a matching result in the browser and `linkedom`. Currently `parseHTML` is only used for HTML content bodies in events. Events with replies have content bodies that look like `<mx-reply>Hello</mx-reply> What's up` so they're parsed as HTML to strip out the `<mx-reply>` part. Before | After --- | ---  |  Before: ```js // Browser (Chrome, Firefox) new DOMParser().parseFromString(`<div>foo</div>`, "text/html").body.outerHTML; // '<body><div>foo</div></body>' // `linkedom` ❌ new DOMParser().parseFromString(`<div>foo</div>`, "text/html").body.outerHTML; // '<body></body>' ``` After (consistent matching output): ```js // Browser (Chrome, Firefox) new DOMParser().parseFromString(`<!DOCTYPE html><html><body><div>foo</div></body></html>`, "text/html").body.outerHTML; // '<body><div>foo</div></body>' // `linkedom` new DOMParser().parseFromString(`<!DOCTYPE html><html><body><div>foo</div></body></html>`, "text/html").body.outerHTML; // '<body><div>foo</div></body>' ``` `linkedom` goal is to be close to the current DOM standard, but [not too close](https://github.com/WebReflection/linkedom#faq). Focused on the streamlined cases for server-side rendering (SSR). Here is some context around getting `DOMParser` to interpret things better. The conclusion was to only support the explicit standard cases with a `<html><body></body></html>` specified instead of adding the magic HTML document creation and massaging that the browser does. - WebReflection/linkedom#106 - WebReflection/linkedom#108 --- Part of #653 to support server-side rendering Hydrogen for the [`matrix-public-archive`](https://github.com/matrix-org/matrix-public-archive) project.
