Rollup Quick Start

Quick start guide for Codecov Bundle Analysis and Rollup.

Step 1: Install the Codecov Rollup Plugin

Install the @codecov/rollup-plugin to your project.

npm install @codecov/rollup-plugin --save-dev
yarn add @codecov/rollup-plugin --dev
pnpm add @codecov/rollup-plugin --save-dev

Step 2: Configure the bundler plugin

Import the bundler plugin, and add it to the end of your plugin array found inside your rollup.config.js file.

Note: You can find your global upload inside your org settings on Codecov

// rollup.config.js
import { defineConfig } from "rollup";
import { codecovRollupPlugin } from "@codecov/rollup-plugin";

export default defineConfig({
  plugins: [
    // Put the Codecov Rollup plugin after all other plugins
      enableBundleAnalysis: process.env.CODECOV_TOKEN !== undefined,
      bundleName: "<bundle project name>",
      uploadToken: process.env.CODECOV_TOKEN,

Step 3: Commit and push your latest changes

The plugin requires at least one commit to be made to properly upload bundle analysis information up to Codecov.

git add -A && git commit -m "Add Codecov bundler plugin" && git push

Step 4: Build the application

When building your application the plugin will automatically upload the stats information to Codecov.

npm run build
yarn run build
pnpm run build
