Rather, it’s the thing that allows frameworks and libraries to run.įor frontend applications, you can run a JavaScript application without a server by just opening the browser, in addition to a lot of manual configuration. Despite popular belief, node.js itself is not a framework. Node.js is a server runtime environment that runs JavaScript outside of a browser. What are node modules and how do you use them? However they are used and implemented, a module is essentially one of the many lego-like bricks that make up the pre-built functionalities of your application. Modules can be used in various parts of an application, bundled into or excluded in builds. Sometimes it comes bundled with the framework you’re using. Sometimes it comes along in the form of 3rd party libraries.
But if you go deeper, you’ll find that the code is often constructed in a way that results in a module.Ī module is a functionality that can be imported or exported.
This is automatically added to auto-generated client packages created by the angular-typescript code generator for OpenAPI 3.0.Īs a result the project that I'm referencing has a "scripts" section within package.There are two main methods of arranging JavaScript code – via a library structure or through a framework. This works by doing three things.įor your dependent package, use the npm library "ng-packagr".
If your dependent package changes frequently, this whole scheme breaks because npm will cache your last version of the project and then blow up when the SHA hash doesn't match anymore with what was saved in your package-lock.json file, among other issues.Īs a result, I recommend using the *.tgz approach with a version update for each change. There are additional errors with a regular development flow with the above solution, as npm's versioning scheme with local files is absolutely terrible. This was all based off of a generated client from an openapi spec that we wanted to keep in a separate location (rather than using copy-pasta for individual files) Npm install (file path) also sort of works. I hope this is clear, and helps someone out. Avoids issues where referencing a tar.gz file locally may be cached by npm and not updated in the main project without lots of cleaning/troubleshooting/re-building/re-installing.Adds a preinstall step to build the referenced npm client package to make sure the dist folder of our dependent package is built.
some-npm-package-angular & npm install & npm run build" Main Project's Package.json File Snippet: "name": "main-project-name", It doesn't always pull in the new one from the referenced npm package when you update it, even if you blow away node_modules and re-do your npm-install for your main project. Pointing to the tar.gz result of (npm package) works for the dependent npm package folder, however this causes issues with the npm cache if you want to update the package.
I also need it to work on Windows AND Unix, so sym-links aren't ideal. I have a local package that I want to always reference (rather than npm link) because it won't be used outside of this project (for now) and also won't be uploaded to an npm repository for wide use as of yet. So I had a lot of problems with all of the solutions mentioned so far.
I haven't found a way to do either, unfortunately :( So, we either need a way to tell node to not resolve this symlink when looking for foo, or we need a way to tell npm to install a copy of mymodule when the file dependency syntax is used in package.json. Instead, we want node to look in /local/myproject/node_modules/, since that's where were running our project from, and where foo is installed. When node loads mymodule and it does require('foo'), node resolves the mymodule symlink, and then only looks in /local/mymodule/node_modules/ (and its ancestors) for foo, which it doen't find. In this scenario, npm sets up myproject's node_modules/ like this: /dev/myproject/node_modules/ Neither of these approaches ( npm link or package.json file dependency) work if the local module has peer dependencies that you only want to install in your project's scope.įor example: /local/mymodule/package.json:
