Important Parameters in Electron application

• 1. Consistent moduleResolution:

• Crucial: The moduleResolution setting MUST be identical in your tsconfig.json, tsconfig.app.json (for the Angular part), and tsconfig.electron.json (for the Electron main process). In most cases, this should be "node". Inconsistent settings are the most frequent cause of module resolution errors in Electron/Angular projects. Your tsconfig.json correctly sets this to "node". Ensure tsconfig.app.json and tsconfig.electron.json also have "moduleResolution": "node".



• 2. target for Main Process:

• Electron Main Process (tsconfig.electron.json): The target option in your Electron main process's tsconfig.json should be set to a Node.js compatible version (e.g., "ES2020" or "ESNext"). This allows for utilizing newer JavaScript features supported in Node.js. Your existing configuration does not give the option for the electron main process. You should create this file and set the correct settings.



• 3. module for Main Process:

• Electron Main Process (tsconfig.electron.json): For the Electron main process, "module": "commonjs" is frequently the most appropriate option, as it aligns with the standard module system of Node.js. However, "ESNext" is also an option. This option should also be added to your tsconfig.electron.json configuration file.



• 4. target and module for Renderer Process (Angular):

* **Angular (Renderer Process):** The `target` and `module` settings within your Angular project's `tsconfig.app.json` are less critical because the Angular CLI (and its bundler, Webpack) handles the transpilation and module bundling. A modern target like `"ES2022"` or `"ESNext"` is usually fine. The Angular CLI handles converting this to browser-compatible JavaScript. Therefore, the main concern here remains *consistency* with the `moduleResolution` setting.



• 5. Other Important Considerations (both processes):

• esModuleInterop: Setting "esModuleInterop": true is generally a good practice for both processes because it enhances compatibility between ES modules and CommonJS modules, a scenario you will likely encounter in an Electron application.

• strict Mode: Using strict type checking ("strict": true) is generally recommended in both parts of your Electron app to improve code quality and reduce runtime errors.

In short: The most important aspect of your TypeScript configuration for Electron is ensuring that the moduleResolution setting is consistent between your main and renderer processes, and that the build process configured by the Angular CLI is correctly set up. Make sure all your tsconfig.json files are harmonized. After these steps are done, focus on making sure that your angular and electron configurations are working together, which may include looking into other aspects of your build process (such as package.json configurations). Pay close attention to error messages to identify which configuration file and which files within the project aren't working together.
