电子锻造：如何指定钩子？

Question

Goal

I want to get rid of some folders before the electron-forge's packaging step, because the option ignore.roge.config in package.json does not get rid of all the intermediate folders that I specify to ignore for some packages. Those intermediate folders are usually generated during a native build process during packaging.

Problem

But adding hooks field with the documented events don't seem to work, eg,

having a package.json field like this seems to add nothing to the equation, ie, I don't see the expected console log.

  "config": {
    "forge": {
      "packagerConfig": {
        "icon": "src/images/myapp",
        "ignore": [
          "/.gitignore",
          "/.vscode",
          "/yarn.lock",
          "/node_modules/mydep/build/",
          "/node_modules/mydep/prebuilds/linux*"
        ]
      },
      "hooks": {
          "prePackage": "async () => {\"console.log("this is prepackage step.");\"} "
      },
      "makers": [
        {
          "name": "@electron-forge/maker-zip",
          "platforms": [
            "darwin",
            "win32"
          ]
        }
      ]
    }
  },

Referring to a related elctron-forge github issue , I've also tried to feed a JS source file to hooks

"hooks": "require:./hooks.js",

where the hooks script looks like

{
    prePackage: async () => {
        console.log('this is prepackage step.');
    }
}

This didn't work either.

Worse, I can't even specify multiple hooks this way:

{
    generateAssets: async () => {
        console.log('We should generate some assets here');
    },
    prePackage: async (forgeConfig, options) => {
        console.error('lbn: prePackage');
    }
}

The above code gives me the following error when running yarn make :

An unhandled error has occurred inside Forge:
Unexpected token ':'
/path/to/myapp/hooks.js:5
    prePackage: async (forgeConfig, options) => {
              ^

Question

What is the right way to specify hooks?

Answer 1

Solved it myself.

We should place the hooks as a normal global module

// ./hooks.js

const fs = require('fs');
const path = require('path');

module.exports = {

postPackage: async (forgeConfig, options) => {
    console.warn('\n\npostPackage: exclude files ...\n\n');
}

}; // module.exports = {

Then refer to it in package.json

"hooks": "require:./hooks.js",
