💽 remix-esbuild-override

⚠️ While I believe you will most likely get a lot of benefit from using this library, it can sometimes destroy your product. Please be sure to verify it and make sure it is safe before releasing it to production.

What is this?

This is a library that makes it possible to change the configuration values of the Remix compiler (esbuild).

For example, Next.js allows you to control webpack option values from a configuration file (next.config.js). Remix does not have that functionality. A member of the development team says in a PR comment that this is because exposing the configuration values would lock in the compiler's choices and also risk breaking the application. I support that argument, but in actual use cases, I often want to change the settings. So I decided to provide that functionality outside of Remix (in this 3rd-party library).

Install

# npm
npm install -D remix-esbuild-override

# yarn
yarn add -D remix-esbuild-override

2. Add remix-esbuild-override to scripts.postinstall in package.json.

"scripts": {
  "postinstall": "remix-esbuild-override"
}

3. Run npm install or yarn install again to run postinstall

How to use

You can define function properties in remix.config.js that can override esbuild configuration values.

// remix.config.js
const { withEsbuildOverride } = require("remix-esbuild-override");

/**
 * Define callbacks for the arguments of withEsbuildOverride.
 * @param option - Default configuration values defined by the remix compiler
 * @param isServer - True for server compilation, false for browser compilation
 * @param isDev - True during development.
 * @return {EsbuildOption} - You must return the updated option
 */
withEsbuildOverride((option, { isServer, isDev }) => {
  // update the option
  option.plugins = [someEsbuildPlugin, ...option.plugins];

  return option;
});

/**
 * @type {import('@remix-run/dev').AppConfig}
 */
module.exports = {
  // ...
};

📝 NOTE: Compilation is executed twice, once for the server and once for the browser.
