Is there a choice for development configuration in gruntjs and angularjs?

In our JavaScript web application, we utilize a config.js file to store global configuration information, such as base API URLs. These values often differ between local development and production environments.

I have explored solutions like creating a development mode for AngularJS using GruntJS, as well as using grunt-replace to generate an on-the-fly configuration file.

However, the challenge lies in the fact that each developer's "development" environment may require different API setups, resulting in varying base API URLs. I am seeking a way for developers to override specific variables in the config without having to commit this information to the Git repository. While I understand that this goes against best practices of having everything in the repository, given that it only pertains to one or two variables in this project, I am willing to make an exception.

Does anyone have any suggestions on how to achieve this type of setup?

Answer №1

If you're looking for a way to streamline your development process, consider utilizing grunt-preprocess. One technique is to store your production and development values in a file like env.json. To enhance this setup, you can employ Grunt to search for an additional file, such as overrides.json or developer.json, which can supplement or overwrite the values from env.json.

var envFile = require('./env.json');

By creating command line options in Grunt using grunt.option – for instance,

var env = grunt.option('env') || undefined;
– you can have the flexibility to disable overriding if necessary.

To access data from an optional file, you can utilize fs.existsSync:

var fs = require('fs');
var developerFile;
if (fs.existsSync('./developer.json')) {
  developerFile = require('./developer.json');
}

A straightforward approach to defining the grunt-preprocess context would involve using the developer.json file if it exists, otherwise defaulting to the env.json file:

context: developerFile ? developerFile : envFile;

This method assumes that the developer file is comprehensive. Another option is to merge the options from the developerFile with those from envFile if the developerFile is present.

Our project utilizes various configuration files, each containing a JavaScript object. Each developer has their own app/configs/developer/config.js file specific to their setup, which is not stored in the source control. By default, the project references the app/scripts/config.js file, which is actually just a symbolic link to the individual developer's config file. Additionally, there are separate app/configs/staging/config.js and app/configs/production/config.js files that are swapped in during the project build process using gruntjj. These configuration files are directly copied into the built solution instead of symbolically linked.

Hopefully, this explanation clarifies the setup we have in place.
