`build:compile` Nuxt hook seems to not being triggered correctly

[kevinmarrec]

Version

v2.3.4

Reproduction link

https://github.com/kevinmarrec/nuxt-build-compile-hook-issue

Steps to reproduce

Clone the reproduction link repository Install deps : yarn or npm install Run in dev mode : yarn dev or npm run dev

Look at the ~/modules/test module, it's gonna output a compile on the therminal when the build:compile hook is triggered.

Change one or multiple times the ~pages/index.vue to trigger a new Webpack compilation through the Hot Reload Module.

What is expected ?

build:compile hook should be triggered at every Webpack compilation

What is actually happening?

build:compile hook is triggered only once (in fact twice but one for server, one for client) at the first compilation, and never for further Webpack compilations.

Additional comments?

See : https://github.com/nuxt/nuxt.js/blob/dev/packages/webpack/src/builder.js#L129

I suggest replacing this line by something similar done for the build:compiled hook, e.g. using the Webpack Compiler hook callback itself. See : https://webpack.js.org/api/compiler-hooks/#compile

So it could be something like

compiler.hooks.compile.tap('???', async () => {
  await nuxt.callHook('build:compile', { name, compiler }
})
