I’m excited to announce the release of Observable Store 2.0 on npm! You can get started using it with the standard npm install command: The Github repository provides information about the specific steps to get started and how Observable Store can be used with various front-end projects. Why Observable Store? Before jumping in to what’s new in 2.0, let me give a quick overview of the Observable Store project in case you’re new to it. Several years ago I was working with a few large companies here in the United States who were building Angular and React apps. One in […]

RxJS Error: “Types of property ‘source’ are incompatible” and How to Fix It

This entry was posted in javascript TypeScript and tagged linking multiple versions packages rxjs on by

I’m working on an npm package that requires RxJS as a peerDependency which means that whatever app uses the package must also install RxJS. Since my npm package project needs RxJS to build, I add it as a devDependency which of course adds it into the node_modules folder of the project. To use my npm package locally in sample apps I have I do the following which is a nice trick to avoid having to publish the package to npm (which I don’t want to do when I’m still working on it): Run npm link [package-name] where package-name is name […]

About a year ago I was browsing the web and came across a site called Scrimba.com. It provided a unique way to learn about web technologies through a live code editor combined with audio that syncs with the code – something you have to actually try out to realize the full potential. Since I do a lot of training for companies the Scrimba tool really caught my eye. I was so impressed with the features Scrimba provided that I decided to contact the creators (Per Harald Borgen and Sindre Aarsaether) to let them know that I thought the tool they had […]
