Use this plugin to specify aliases for single or multiple files and optionally define alias extractors for specific files (e.g. paths in tsconfig.json, or moduleAliases in package.json)
Webpack cannot create aliases for specific file.
For example, imagine you have 2 entry points, A and B in your webpack config which are basically separate projects. They do not import anything from each other, but they share some files in common folder (standard real-life monorepo structure).
If you use aliases you might find it natural to use @ symbol to reference the root of your project. But you can't specify @ to mean project A root and project B root at the same time depending on where it is referenced from in a single config file.
This plugin solves this issue by introducing file-relative aliases.
npm i @heniker/file-alias-webpack-plugin
A use-case I had in mind for this plugin is extracting aliases from multiple tsconfig.json files.
If that's what you're looking for, you don't need to configure anything in order for it to work:
const FileAliasPlugin = require('file-alias-webpack-plugin')
const plugin = new FileAliasPlugin()
module.exports = {
resolve: {
// Place it in resolve.plugins, not in regular plugins
plugins: [
plugin,
],
},
}See example/2 for 'real-world' example.
You should have typescript typings avaliable once you install this plugin.
Right now project uses webpack for compatibility reasons (esm support is weird). The project is small, so that's not a big deal. But there is no good enough reason to use webpack to bundle a library.
For more complex use-cases you might have to set transpileOnly: true for ts-loader. ts-loader uses it's own path-resolver in order to type-check typescript code. This needs to be solved, possibly by using resolveModuleName.
