What steps are required to start running Karma once it has been installed?

I'm experimenting with using karma for various watch processes.

To start, I globally installed karma by running:

npm i -g karma

After that, I executed karma start karma.conf.js and it ran successfully.

Now I want to install karma locally within the project by running 

npm install karma

The installation seems to have completed without issues as I can see the karma folder in node_modules, but it looks like node_modules/karma/bin/karma is not an executable file.

What would be the correct way to run karma after installing it locally?

Answer №1

If you're working on a Windows machine (I'm using Windows 10), my suggestion is to include the following code snippet in your package.json file.

 "scripts": {
    "test": "cd ./node_modules/karma/bin/ && karma start"
  },

Once you've added this, you can run the command npm run test from your terminal.

I find it convenient to avoid installing global CLIs for these tools and instead opt to run them locally within my project using a script. This way, I can easily manage versions in dev dependencies without worrying about conflicts between global and local installations.

"devDependencies": {
    "karma": "^1.4.0"
 }

Answer №2

If you've just installed Karma locally and need to run it, follow these steps:

# To Run Karma:
$ ./node_modules/karma/bin/karma start

Running 

./node_modules/karma/bin/karma start
every time can be tedious, so it's recommended to install karma-cli globally. This is especially useful for running Karma on Windows using the command line.

$ npm install -g karma-cli

After installing karma-cli, you can easily run Karma by simply typing 'karma' from anywhere, ensuring that it always runs the local version.
