@funboxteam/rebuild-in-progress-webpack-plugin

Webpack plugin that creates the file indicator at the beginning of the build and deletes it at the end.

Rationale

Sometimes external programs have to know the project building state. E.g. it's important to have this knowledge for tests running (especially E2E), because testing should be started when the project is completely built.

To solve this problem RebuildInProgress plugin was created. It creates the file node_modules/.rebuildInProgress when webpack starts to build the project and removes it at the end.

Usage

Add the plugin in plugins array as usual:

const RebuildInProgressPlugin = require('@funboxteam/rebuild-in-progress-webpack-plugin');

module.exports = {
  plugins: [
    new RebuildInProgressPlugin()
  ]
}

Set the path to the file if the default one isn't suitable:

const RebuildInProgressPlugin = require('@funboxteam/rebuild-in-progress-webpack-plugin');
const rebuildInProgressPath = 'node_modules/.alternativeName';

module.exports = {
  plugins: [
    new RebuildInProgressPlugin(rebuildInProgressPath)
  ]
}

Build state watching

Here's an example of watching for build state using fs:

const fs = require('fs');
const rebuildInProgressPath = 'node_modules/.rebuildInProgress';

fs.watch(path.dirname(rebuildInProgressPath), (eventType, filename) => {
  if (eventType === 'rename' && filename === path.basename(rebuildInProgressPath)) {
    if (fs.existsSync(rebuildInProgressPath)) {
      // Build has been started
    } else {
      // Build has been completed
    }
  }
});
