webpack-teamcity-bundle-size-plugin

A webpack plugin that reports individual bundle sizes to TeamCity using buildStatisticValue service messages.

To Install

In your project run a npm install command:

npm install webpack-teamcity-bundle-size-plugin --save-dev

Usage

Import the plugin at the top of your webpack.config.js file:

const WebpackTeamcityBundleSizePlugin = require('webpack-teamcity-bundle-size-plugin')

In the plugins section of your config, add a new instance of this plugin:

{
    ...
    plugins: [
        new WebpackTeamcityBundleSizePlugin()
    ]
    ...
}

Plugin Output

The plugin will only output messages if TEAMCITY_VERSION is present. You can test the reporter by temporarily setting the environment variable:

export TEAMCITY_VERSION="your_version"

If you have this environment variable set locally, running your webpack build will output TeamCity service messages:

##teamcity[buildStatisticValue key='app.js' value='40241']
##teamcity[buildStatisticValue key='app.css' value='1762']

The key is set to the bundle file name, the value is the bundle file size in bytes.
