webpack自定义插件

感受下webpack的插件能力，在打包后创建一个json文件

const fs = require("fs");
const PLUGIN_NAME = 'CreateJsonPlugin'

class CreateJsonPlugin {
  apply(compiler) {
    compiler.hooks.afterEmit.tapAsync(PLUGIN_NAME, async (compilation, cb) => {
      const logger = compilation.getLogger(PLUGIN_NAME)
      // const logger = compiler.getInfrastructureLogger(PLUGIN_NAME)
      logger.info('create version.jon')
      const path = './dist/version.json'
      const content = `123456789`
      await fs.writeFileSync(path, content)
      cb()
    })
  }
}

module.exports = CreateJsonPlugin
