This Gist works for CRA 3. For CRA 4, you can try community maintained craco plugin for converting to a single-spa application at https://github.com/hasanayan/craco-plugin-single-spa-application (thanks @hasanayan):

1. Install react-app-rewired, as explained in https://github.com/timarney/react-app-rewired.
2. Create a file in src called single-spa-entry.js (or tsx for typescript)
3. Modify config-overrides.js, as shown in the config-overrides.js file provided in this gist.
4. (Optional) remove src/main.js, since single-spa-entry is the new entry
5. (Optional) remove public/index.html, since single-spa applications share a single html file, instead of one html file per project.

// TextEncoder/TextDecoder polyfills for utf-8 - an implementation of TextEncoder/TextDecoder APIs

// Some important notes about the polyfill below:
// Native TextEncoder/TextDecoder implementation is overwritten
// String.prototype.codePointAt polyfill not included, as well as String.fromCodePoint
// TextEncoder.prototype.encode returns a regular array instead of Uint8Array
// No options (fatal of the TextDecoder constructor and stream of the TextDecoder.prototype.decode method) are supported.
