A guide on refreshing the dependencies list within Angular's node modules and package.json files

A close friend sent me the angular src folder, which I used to create a new Angular project. However, when I replaced my newly created src folder with my friend's and tried running the application using npm start, I encountered errors related to missing dependencies in the node_modules directory. How can I resolve this issue?

I have tried various solutions like running "npm start", deleting and reinstalling node modules, but the problem persists. Any help in solving this error would be greatly appreciated. Thank you.

To resolve the issue effortlessly, grab the package.json file from your friend's project and place it at the same level as the src folder. Execute npm install to automatically install all the necessary dependencies, which will generate the node_modules folder.

If you encounter difficulties, create an empty file named package.json in the same directory as the src folder. Then, manually install each dependency using the command npm install <package_name>. This way, each package will be added to your package.json file and the node_modules folder will be created.

  • npm install jsencrypt
  • npm install @microsoft/microsoft-graph-client
  • etc.

Keep in mind that by installing packages individually, you may end up with different versions compared to those in your friend's project. This mismatch could lead to compatibility issues.

Additionally, there appears to be a configuration file located in the assets folder at assets/config/config.json containing information about the ApiServerUrl. It is advisable to obtain this crucial file from your friend's project as well.

For more insights on the package.json file, refer to the Documentation.
