Rollup Quick Start

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.

YYou can find a Codecov upload token on the Configuration page for your repository, under General, or your organization settings page in the Codecov UI. For more information, see the documentation.

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

export default defineConfig({
  plugins: [
    // Put the Codecov Rollup plugin after all other plugins
    codecovRollupPlugin({
      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 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
