我已将babel-plugin-rewire
的问题与这几个文件分开了。我想弄清楚为什么console.log(dep)
仍然将fetch记录为函数而不是true
,因为它应该被替换。
.babelrc
{
"presets": [
"babel-preset-stage-3",
[
"babel-preset-env",
{
"targets": {
"node": "4.0.0"
}
}
]
],
"plugins": [
"babel-plugin-rewire"
]
}
dep.js
const fetch = require('isomorphic-fetch')
module.exports = {fetch}
use.js
const dep = require('./dep')
dep.__Rewire__('fetch', true)
console.log(dep)
的package.json
{
"scripts": {
"start": "babel-node ./use.js"
},
"devDependencies": {
"babel-cli": "^6.26.0",
"babel-core": "^6.26.0",
"babel-plugin-rewire": "^1.1.0",
"babel-preset-env": "^1.6.1",
"babel-preset-stage-3": "^6.24.1"
},
"dependencies": {
"isomorphic-fetch": "^2.2.1"
}
}

好的,刚刚学会了rewire
没有改变模块范围(duh)的艰难方法。
dep.js
var Path = require('path');
var env = 'production';
console.log(env)
module.exports = function(name) {
console.log(env)
return Path.normalize(name)
}
use.js
var normalizer = require('./dep.js');
normalizer.__Rewire__('Path', {
normalize: (name) => name
});
console.log(normalizer('/foo/bar//baz/asdf/quux/..'))
normalizer.__Rewire__('env', 'testing');
console.log(normalizer('/foo/bar//baz/asdf/quux/..'))
normalizer.__ResetDependency__('Path');
console.log(normalizer('/foo/bar//baz/asdf/quux/..'))
日志:
