Use npm package fork

Any JS developer here?

I want to use this library but it has a bug. It seems it’s fixed in this fork GitHub - paolo-ciucci/ngx-daterangepicker-material: Pure Angular 2+ date range picker with material design theme, a demo here:

I usually do npm i <the-package>, is it possible to use the fork instead? Doing npm i doesn’t work because the folder in node_modules doesn’t include the dist files.

Use yarn

yarn add
yarn add v1.22.10

Often the approach is to publish the package to npm with a different name (for example, under your own user scope or a company scope, eg. @imok/ngx-daterangepicker-material) and use that until the upstream version is fixed.

You can also use npm link (or yarn link) to use a local package version (from some folder on your computer) rather than a version from npm, but that’s frustrating to deal with if there’s multiple developers working on the project or if you want to push it anywhere.

@nem If files are missing from the repo, Yarn may not work 100% either.

Basically what Daniel said, publishing yourself under different name is the best option for long-term because usually you need to build before release to NPM.

However, one solution I like a lot is using patch-package. Not the best solution and not maintainable at all but for a very small fix (in this case 2 lines) it should work very well. We use this in production for minor bug that upstream haven’t fixed yet / pending merge / release.

How it works is you install your package, then modify the code in node_modules, then run patch-package to allow it to look for changes and save the diff somewhere. During installation (more specifically postinstall), it will then apply that diff patch.

Thank you all.

I published it under a different name but Angular did not recognize the module. I haven’t tried using something like @imok but it seems interesting.

I spent too many hours trying to fix that without success, so I’ll leave it as it is and removing some user functionality.

Also today I received the notice we are going to refactor the project (which started some weeks ago) because planning is meh. I’m going to look for a more complete framework than Ionic now that I have the chance.
