Share node_modules in monorepos. Best friend for pnpm's module isolation and module singletons sharing.
Use it as simple as:
// vite.config.ts
import { defineConfig } from 'vite';
import sharedModulesPlugin from 'vite-plugin-shared-modules'
import tsconfigPaths from 'rollup-plugin-tsconfig-paths';
export default defineConfig({
plugins: [
sharedModulesPlugin({
packageName: '@monorepo/shared',
}),
// necessary for resolving modules in `node_modules`
tsconfigPaths({
// specify the project's tsconfig.json, which configured paths mapping.
tsConfigPath: join(__dirname, '../../tsconfig.json')
}),
]
});then you can import singletons by this way:
import foo from '@monorepo/shared/foo'
import bar from '@monorepo/shared/bar'is equivalent to
import foo from '@monorepo/shared/node_modules/foo'
import bar from '@monorepo/shared/node_modules/bar'moreover for getting type-safe, add tsconfig paths mapping:
// tsconfig.json
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@monorepo/shared/*": ["./packages/shared/node_modules/*", "./packages/shared/node_modules/@types/*"]
}
}
}the example above we assume the package @monorepo/shared is located under ./packages/shared.
The plugin options signatures:
export type SharedModulesPluginOption = {
packageName: string,
subpath?: string,
nodeModules?: string,
sourceMap?: boolean,
}The default options:
export const defaultSharedModules = {
subpath: '',
nodeModules: 'node_modules',
sourceMap: true,
}
