When working with npm packages you often want to test your package without having to publish it to npm. This enables you to have a quicker feedback...

Great article! Just adding some more points which might be helpful.
You don't need to pack your library to test it.
Just point the package.json dependency to actual library folder instead of the packed version and do npm i once.
npm creates a link to actual folder inside node_modules
Saves you additional steps of packaging and installing it after every change in your test project
Thanks for highlighting this use case. I have done this in the past but seemed to run into issues with the linking. Maybe I should give it another go though as does save a few steps.
However, I still like the additional confidence of working off the same item that will actually end up in npm.
I didn't know about this method, I always use
npm link.For developing this is very handy as it is also possible to get autorefresh/hmr
For testing a package before publishing using
npm packseems like a much better alternative becausenpm linkdoes not care about the files property. All files in the project are included as it is just a symlink.And I just found out that this should work as well:
Thanks for sharing!
npm linkuses symbolic links to link to raw source files as opposed to what the end-users will see, which is usually the build artifacts and maybe a subset of the source files copied over. Usingnpm linkdoes not ensure you've packaged your package correctly.How to do this. Can you explain with code. Please.
The official docs have some examples of this with an explanation of what it does.

great article man
Thanks! I have come back to the draft a few times to remind myself so how to do it so thought I should share it.
absolutely
With PHP Composer I can keep my code and dependance linked to Packagist and just replace the folder with a SimLink locally while I develop my code.
With NPM this won't work. I have to use "file:../_packages/my-package-name" as you mentioned but now my CI build is broken...
I must be doing something wrong or this seems like a really big inconvenience.
God bless u!
I should delete my
node_moduleandpackage_lock.jsonto see the changes!when I test it again
Also Do you have any idea about this question?
Thanks in advance
@scooperdev Thanks for the blog...
Btw, do we need to provide a relative path here?
What if the calling application is a different project altogether? How too reference this file?
May be copying it to the project and keep it at the package.json level and call?
