I’m working on an npm package and I’m trying to figure out the best way to handle test-related stuff. I know we’re supposed to put test dependencies in the devDependencies section of package.json. This makes sense because regular users don’t need those extra packages.
But I’m wondering about the actual test code itself. Should I add my test folder to the .npmignore file? This way, when someone installs my package, they won’t get all the test files too.
Is this a good practice? Or am I missing something important here? I want to keep my package lean and only include what’s necessary for users.
Here’s a simple example of what I’m thinking:
// .npmignore
test/
coverage/
.eslintrc.js
Does this look right? Any advice would be really helpful!
Hey there! I’ve dealt with this exact issue before, and you’re definitely on the right track. Adding your test folder to .npmignore is a solid practice. It keeps your package lean and focused, which users appreciate.
One thing I learned the hard way: make sure you’re not accidentally ignoring files that are actually needed for your package to function. I once excluded a crucial config file and spent hours debugging why my package wasn’t working for others.
Another tip: consider using a .npmignore file in conjunction with the “files” field in your package.json. This gives you more fine-grained control over what gets included. It’s like a whitelist approach, which can be safer.
Lastly, don’t forget about your documentation. Make sure your README mentions how to run tests if someone clones your repo, even if the tests aren’t in the npm package. It’s a small thing, but it helps contributors a lot.
Hope this helps! Let me know if you have any other questions.
Your approach is spot-on. Adding test directories to .npmignore is indeed best practice. It keeps your package slim and focused on what users actually need.
I’d suggest taking it a step further. Consider using the ‘files’ field in package.json instead. It’s a whitelist approach, giving you more precise control over what’s included. Something like:
"files": ["lib", "dist", "README.md"]
This way, you explicitly state what should be in the package, reducing the risk of accidentally including unnecessary files.
Remember to keep your .gitignore and .npmignore in sync. It’s easy to forget and can lead to confusion down the line.
Lastly, if you’re using TypeScript, don’t forget to exclude your test files in your tsconfig.json as well. It’s a small detail that can save you headaches later.
yo, ur on point! .npmignore is great 4 keepin tests out. but heres a pro tip: use the ‘files’ field in package.json instead. its like a VIP list for ur package.
example:
“files”: [“src”, “dist”]
this way u know exactly whats goin in. less chance of oopsies. trust me, itll save u headaches later!
