我需要知道构建的哈希,所以我试图在回调函数中捕获它:
const compiler = webpack(webpackConfig, function (err, stats) {
debug("Hash", stats.hash)
})
但当我这样做的时候,会发生一些奇怪的事情:我得到了2个构建,只能捕获1个哈希——显然我需要另一个,而不是回调中的那个。
回调时的输出:

好的,我发现了。。。在Webpack的源代码中,如果有回调给webpack(options, callback)
,那么它会自动运行自己:
function webpack(options, callback) {
...
if(callback) {
...
compiler.run(callback);
}
return compiler;
}
如果有人想添加回调,请按如下方式添加plugin
:
compiler.plugin("done", stats => {
debug(hash)
})
