vite-plugin-custom-tsconfig

library1.0.4jsnpmunverified

A Vite plugin (v1.0.4, latest) that lets you use custom tsconfig filenames like tsconfig.build.json or tsconfig.app.json with Vite. It works by copying your chosen tsconfig.*.json to tsconfig.json before Vite starts and removing it after the build finishes. This is a simple solution for monorepos or projects needing different TypeScript configurations for different environments. The plugin is lightweight, has no dependencies, and supports both ESM and CJS imports. Unlike alternatives like tsconfig-paths-webpack-plugin for Webpack, this plugin is Vite-specific and focuses solely on swapping tsconfig.json files.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import customTsConfig from 'vite-plugin-custom-tsconfig'

✗ const customTsConfig = require('vite-plugin-custom-tsconfig')

Uses default export, but named export also available. Since v1.0.3, both work.

customTsConfig

✓ import { customTsConfig } from 'vite-plugin-custom-tsconfig'

✗ import customTsConfig from 'vite-plugin-custom-tsconfig'

Named export added in v1.0.3. Prefer default import for simplicity.

Plugin

✓ import type { Plugin } from 'vite'

✗ import { Plugin } from 'vite-plugin-custom-tsconfig'

Plugin type is from Vite, not this package.

Shows how to use the plugin to set a custom tsconfig filename (tsconfig.app.json) in your Vite configuration.

// vite.config.ts import customTsConfig from 'vite-plugin-custom-tsconfig'; import { defineConfig } from 'vite'; export default defineConfig({ plugins: [ customTsConfig({ filename: 'tsconfig.app.json', }), ], });

Debug

Known issues

gotchaThe plugin copies and deletes tsconfig.json. Ensure no other tool relies on tsconfig.json being present at the same time.

fix

Run Vite builds sequentially or ensure other tools are not watching for tsconfig.json changes.

affects: >=1.0.0

gotchaThe plugin does not resolve paths or merge configs; it simply overwrites tsconfig.json with the specified file. If your custom tsconfig references other configs via extends, those must be correctly relative.

fix

Ensure your custom tsconfig extends relative paths correctly.

affects: >=1.0.0

gotchaThe plugin may cause issues with editors (VS Code) that watch for tsconfig.json changes, as the file is temporarily replaced.

fix

Copy the custom tsconfig manually or use a symlink during development.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'vite-plugin-custom-tsconfig'

Package not installed or not in devDependencies.

fix

Run `npm install --save-dev vite-plugin-custom-tsconfig`

TypeError: customTsConfig is not a function

Using named import when package uses default export (or vice versa).

fix

Use `import customTsConfig from 'vite-plugin-custom-tsconfig'` or `import { customTsConfig } from 'vite-plugin-custom-tsconfig'` consistently.

ENOENT: no such file or directory, open 'tsconfig.build.json'

The specified filename does not exist in the project root.

fix

Create the file or adjust the `filename` option in the plugin config.
