On rare occasions I find myself having to clean my development environment (i.e. delete the following folders - node_modules, build, coverage, etc). As this could include multiple folders, I decided the best approach was to create a script. I also hate typing the same commands over and over again, save those fingers!ποΈ
I wanted a cross platform approach (works on both Linux and Windows), rimraf
is the ideal candidate as it's an npm package that deletes folders recursively and works cross platform.
Why make the solution cross platform? So all developers that collaborate on the code base can benefit.
Now we could install rimraf globally, but we can't guarantee that another developer has this installed, which will result in the script failing when executed.
A cleaner approach is to have the dependency installed as a dev dependency. However, this will cause issues as rimraf
will try to delete the node_modules folder where rimraf
is currently executing from. Hence it would try and delete itself and fail.
So to resolve this issue, we can execute rimraf
when we need to run it (one-off invocation without local installation) via the npx
command. The npx
command was introduced with npm 5.2.0 and later.
The Destroy Script π₯
Below is an example of the destroy script, this will delete the node_modules, build and coverage folders and all their contents.
{
"scripts": {
"destroy": "npx rimraf node_modules build coverage",
}
}
Execute Destroy Script
The destroy script can be executed either by using npm or yarn.
npm run destroy
Or
yarn destroy

Instead of "destroy" you should use "clean" like in "make clean" ;) Destroy sounds too harshful imho!
I usually have a "clean" script that deletes just the build artifacts. Hence the reasoning behind the name "destroy", as hopefully devs will know it applies to destroying all artifacts and dependencies.
then go with "cleanall", as destroy implies removing something that cannot be recuperated easily. My 2 cents ;)
Nice one! I was using a bash file for it but this looks better, thanks. :)
No worries, better to have it as a script in the package.json, then it's not dependant on the OS and it's also version controlled.
Except the script doesn't work on Windows.
it does. ive tested it
Yeah that's what I meant, bash is not working with win cli. I also updated:) Cheers
Nice one π
No worries, glad you liked it.
I like that! π₯
Thanks for sharing! I like this idea.
No worries, glad you found it useful.
I thought that in package.json, you don't need to put in npx.
This would only work if you had rimraf as a dependency or rimraf was installed globally.
