npm version cheatsheet

npm uses Semantic Versioning

npm uses Semantic Versioning. Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes,
MINOR version when you add functionality in a backwards compatible manner, and
PATCH version when you make backwards compatible bug fixes.

Nx

Nx is a suite of powerful, extensible dev tools to help you architect, test, and build at any scale — integrating seamlessly with modern technologies and libraries while providing a robust CLI, caching, dependency management, and more.

It has first-class support for many frontend and backend technologies, so its documentation comes in multiple flavours.

Principles

Everything I Know About UI Routing

Definitions

Location - The location of the application. Usually just a URL, but the location can contain multiple pieces of information that can be used by an app
1. pathname - The "file/directory" portion of the URL, like invoices/123
2. search - The stuff after ? in a URL like /assignments?showGrades=1.
3. query - A parsed version of search, usually an object but not a standard browser feature.
4. hash - The # portion of the URL. This is not available to servers in request.url so its client only. By default it means which part of the page the user should be scrolled to, but developers use it for various things.
5. state - Object associated with a location. Think of it like a hidden URL query. It's state you want to keep with a specific location, but you don't want it to be visible in the URL.

How to run a redis server using Docker-for-Mac

This will work with other flavours of Docker as well.

Run the following command:

docker run --name my-redis -p 6379:6379 --restart always --detach redis

This will download and run redis, set to auto-restart when your machine starts and bound to port 6379 on your machine.

Windows 10 version 2004 - Installing Node.js on Windows Subsystem for Linux (WSL/WSL2)

UPDATE (Fall 2020): This gist is an updated version to the Windows 10 Fall Creators Update - Installing Node.js on Windows Subsystem for Linux (WSL) guide, I usually just keep here notes, configuration or short guides for personal use, it was nice to know it also helps other ppl, I hope this one too.

Windows updated windows subsystem for linux to version 2, as the F.A.Q stated you can still use WSL version 1 side by side with version 2. I'm not sure about existing WSL machines surviving the upgrade process, but as always backup and 🤞. NOTE: WSL version 1 is not replace/deprecated, and there ar

Modules are very useful, but beware of the following pitfalls:

do not redeclare a component, directive, etc. in more than one module

modules do not create their own DI context, so injectables are available also outside the module

unless the module is lazy loaded, in that case a separate DI context is created by the router to avoid accidental injectable overrides and prevent hard to troubleshoot bugs >- if you have a shared module that needs to be added to a lazy loaded module, make sure that it does not have providers, because that would create duplicate service instances (unless that is the intended behavior)
