Vite plugin for sending sourcemaps to Flare

The Flare Vite plugin helps you send sourcemaps of your compiled JavaScript code to Flare. This way, reports sent using the @flareapp/flare-client will be formatted correctly.

Additionally, it automatically passes the Flare API key to @flareapp/flare-client. This way, flare.light() works without any additional configuration.

Check the JavaScript error tracking section in the Flare documentation for more information.

Looking for the Flare client? Go to the @flareapp/flare-client repo.


Install the plugin using NPM or Yarn:

yarn add @flareapp/vite-plugin-sourcemap-uploader
# or
npm install @flareapp/vite-plugin-sourcemap-uploader

Next, add the plugin to your vite.config.js file:

import { defineConfig } from 'vite';
import flareSourcemapUploader from '@flareapp/vite-plugin-sourcemap-uploader';

export default defineConfig({
    plugins: [
            key: 'YOUR API KEY HERE'

Run the vite build command to make sure the sourcemaps are generated. You should see the following lines in the output:

@flareapp/flare-vite-plugin-sourcemaps: Uploading 12 sourcemap files to Flare.
@flareapp/flare-vite-plugin-sourcemaps: Successfully uploaded sourcemaps to Flare.


  • key: string (required): the Flare API key
  • base: string: the base path of built output (defaults to Vite's base path)
  • runInDevelopment: boolean: whether to upload sourcemaps when NODE_ENV=development or when running the dev server (defaults to false)
  • version: string: the sourcemap version (defaults to a fresh uuid per build)
  • removeSourcemaps: boolean: whether to remove the sourcemaps after uploading them (defaults to false). Comes in handy when you want to upload sourcemaps to Flare but don't want them published in your build.
