有没有办法从 .js 文件解析environment.ts 文件?
export const environment = {
...,
production: false,
...
};

就像是
beforePrepare.js
module.exports = function (ctx) {
let environmet = TOOL.parse(src/environments/environment.ts);
console.log(environment); --> PRINT {..., production: false, ...}
}

正则表达式也能完成这项工作吗?
我需要这个来实现科尔多瓦钩子
正则表达式可以用作快速但肮脏的解决方案:
const s = `
// Some comment
export const environment = {
production: false,
apiUrl: 'http://my-api-url',
testUser: {
name: 'John Doe',
age: 25
}
};
export const otherStuff = {
answer: 42
};
`;
const regex = /export const environment = (\{[^;]*\});/m;
const match = regex.exec(s);
const environment = eval(`(${match[1]})`);
console.log(environment);Run Code Online (Sandbox Code Playgroud)
对于更复杂的情况,您需要 TypeScript 解析器。
