Changelog

  • 2021-06-01

    Ignore dynamic module. Beacuse the dynamic module(Their name is null) will import by entry, it is not necessary to store.

  • 2018-04-16

    Use webpack@v4 event hooks.

起源

最近在给项目的生成文件需要添加形如 [hash:8] 版本号并把该版本号同步记录到某配置文件内,想到每次更改生成新的打包文件,都要去版本配置的文件里更改版本号,程序员最不喜欢做这种重复性的劳动了,就想着有没有 webpack 插件能做类似的功能,能把我的版本号写到配置文件里去,找了一圈只找到 webpack-version-hash-plugin ,而且只能输出在固定的位置和固定的格式 (╯‵□′)╯︵┻━┻ ,无奈,我当时直接用了时间戳作为构建的版本号,后来就做了现在的这个插件,我可以在插件的 cb 函数中把获取到的版本号写到我单独的 json 文件中,当然,这里获取到的是完整的hash 值,可以按需截取。
