在我的Electron应用程序中,我有一个大文件constants.js
,它可以在Render Process(Web,ESM Modules)中导出和使用。我还想在应用程序的主进程(节点,CJS模块)中导入此文件。
即使使用最新版本的Electron / Node中提供的新实验模块,也需要将我的文件扩展名从constants.js
更改为constants.mjs
。由于此文件在整个应用程序中都是大量引用,因此无法更改文件扩展名。
是否可以在渲染和主要进程之间共享我的constants.js
文件?

constants.js
export {
Location,
People,
};
const Location = {
COUNTRY: "Canada",
CITY: "Montreal"
};
const People = {
OWNER: "Mr. Owner",
MANAGER: "Mrs. Manager",
DEVELOPER: "Mr. Developer",
};
index.js(渲染过程,Web ESM)
import * as C from "../support/constants.js";
console.log(`${C.People.DEVELOPER} lives in ${C.Location.CITY}`);
mainElectron.js(主要流程,节点CJS)
const electron = require("electron");
const app = electron.app;
app.on("ready", () => {
//How to access constants.js file here?
});
对于今后可能会遇到同样问题的任何人,我通过使用以下方法解决了这个问题:
ESM: Tomorrow's ECMAScript modules today!。
此外,我重新构建了我的代码,以便我在Main Process和Renderer Process之间共享的常量文件现在位于带有Main Process文件的./build
文件夹中。
