ActionHero VS nyc

ActionHero.js is one of the most well-known API frameworks. It will help you quickly develop scalable and reusable Node.js API servers for your projects. ActionHero acts as a toolkit that will allow you to build such API servers that will initially work together with existing applications and platforms. With tens of thousands of users, you can always find the right answers and ideas to ensure a daily efficient workflow with ActionHero.

Two of the major components of the @grouparoo/core application are a Node.js API server and a React frontend. We use Actionhero as the API server, and Next.JS for our React site generator. As we develop the Grouparoo application, we are constantly adding new API endpoints and changing existing ones.

At Grouparoo, we use Actionhero as our Node.js API server and Sequelize for our Object Relational Mapping (ORM) tool - making it easy to work with complex records from our database. Within our Actions and Tasks, we often want to treat the whole execution as a single database transaction - either all the modifications to the database will succeed or fail as a unit. This is really helpful when a single activity may create or modify many database rows.

Hard to say without knowing /what/ you want to accomplish in your CI process, so maybe some open source examples will help:

* A "complex" library (node-resque). In CI (CircleCI) we install deps, compile Typescript to JS, test on 3 versions of node, and build docs. 4 min w/ some parallelization https://app.circleci.com/pipelines/github/actionhero/node-re...

* A web server framework (actionhero): In CI(Github Actions) we install deps, compile Typescript to JS, test on 3 versions of node, and build docs. 7 min w/ some parallelization https://github.com/actionhero/actionhero/actions/runs/801273...

* A Monorepo (Grouparoo): In CI (CircleCI) we install deps, compile Typescript to JS, run migrations, check licenses, test UIs, CLI tools, Plugins, and try out a few different databases. 5 minutes with rather extreme parallelization https://app.circleci.com/pipelines/github/grouparoo/grouparo...

Websockets are the answer. Checkout https://www.actionherojs.com/ for a framework that works great as game server.

Native code coverage via v8 or istanbul.

Writing tests is essential, and knowing whether you test all the required cases for your logic is even more critical. The most common testing coverage tool is Istanbul, where you can see how well your tests exercise your code by lines, functions, and branches. Below is an example of how the test coverage report looks in your terminal:

Here is a quote from istanbul, one of the most used code coverage tool:

Unit testing framework was already implemented, using Vitest so I started hacking by setting up a coverage provider to explicitly identify the covered/uncovered lines and mentioned this to the maintainer in the comments. I used Istanbul 🇹🇷 for this purpose.

Your project probably has a coverage report. If you’re using Jest as your unit test runner, generating a coverage report is embedded in it. It is done with Istanbul under the hood, which generates a nice HTML page presenting the entire project unit test coverage.

> This is a rant written by someone with just enough understanding to be dangerous, but not quite enough wisdom to know why things are still the way they are. Most of the complaints raised are subtly inaccurate.

Author seems aware of CAP_NET_BIND_SERVICE: https://source.small-tech.org/site.js/app/-/issues/169 and https://github.com/istanbuljs/nyc/issues/1281 – the "side effects" are NodeJS explicitly checking for it, so that's a NodeJS thing and not a Linux thing.

Yet curiously it's completely unmentioned in this article, in spite that this is probably what started the author's dislike of privileged ports. I guess it was inconvenient as it got in the way of angrily ranting.

This approach will create two json coverage files, which will be merged together by NYC. Therefore the results will be purely local. If You don't mind using online tools like Codecov or Coveralls for merging data from different tests, then go ahead and use them. They will probably also be more accurate. But if You still want to learn how to get coverage from E2E, then please read through

https://istanbul.js.org/ measures how much of your code is covered by tests

Jest uses a package called Istanbul to provide test coverage metrics such as statement, branch, function, and line coverage so that you can understand and enforce the quality of your test suite, providing more confidence in releases.

So let’s see if nyc (the code coverage generator) can help with that. Hmm… this documentation seems interesting! So basically what I understand from it is that I need to collect all the reports from the different packages and then run the nyc report over it. The flow should be like this:
