javascript - webpack 通过 yarn : stop process and exit code 1 on warning

Question

使用 Webpack 运行构建过程时，我收到了一些警告。我考虑了一些警告错误，IMO，它应该停止构建过程。

> yarn build:staging
yarn run v1.10.1
$ webpack --env.staging --env.NODE_ENV=staging
Version: webpack 4.23.1

[...]

[795] ./src/index.css 1.05 KiB {0} [built]
    + 793 hidden modules

WARNING in ./src/assets/banner/3.jpg
Module build failed (from ./node_modules/image-webpack-loader/index.js):

Done in 26.03s.

这个“警告”应该停止整个过程并退出。 有没有办法告诉以 yarn 作为驱动程序的 webpack 在出现某种警告时停止(并返回错误代码)？ 我的 CI 流程认为一切正常，这不是我预期的行为.

您可以从 Webpack 实例的 stats 对象访问 errors 和 warnings，然后选择拒绝/退出进程:https://github.com/webpack/docs/wiki/node.js-api

例如:

if(stats.errors.length > 0 || process.warning.length > 0) {
  process.exit()
