One of the best productivity boosters I've ever seen! LOVE your channel and this series!

[Papapiishu]

I'd love to see something about writing tests for React components

[MichaelCampbell]

Thanks, this helped a lot with a new express/typescript/jest project. And never heard about Wallaby, so that's cool too.

Great video. I think the no BS TS series is essential viewing for Typescript developers. Just incredible content!

[francis_n]

My company has just bought us Wallaby licenses and once you go Wallaby there is no way you can go back to the terminal. Such a productivity boster!

[Bill-cwei]

Wallaby is a great time saver, thanks for letting us know!

[EnLaMitad]

I had to use jest/enzyme for a React project at school. Such a pain in the butt. :/ I'm looking forward to your video about testing React components!

I have worked in pretty big projects and wallaby just was not up to the task. It is an awesome tool and it works great on smaller projects but once you use in big ones it just hangs itself and everything gets laggy in vs code. I had to stop using unfortunately (that was a couple of years a go not sure how it is nowadays). I have tests running in watch mode in parallel while I code. I usually use watch typ ahead for jest so i filter the tests I want to be running (so I don't run all tests)

Wallaby seems to be a productivity enhancing tool. Can't wait to try it out.

I have no idea what you arte type in the terminal @1:40 to @3:10. What command are you entering to run ts-jest? By the way, , THANK YOU for putting all this together. Your hard work is MUCH appreciated!

@Jack Harrington, I like all your "No BS TS" videos. Thanks for spreading the knowledge.

Can you share how do you get the inline "Run | Debug" option to run the script right from the editor?

[denilsoncosta]

i'd like to see ts-jest with Next.js

[dinoscheidt]

Just came here randomly to look up wallaby. But i wonder if yarn is still necessary since npm has adopted lock etc as well. At least that is the reason why I used it way back. Any reason why you prefer yarn over npm nowadays? (Honest question) ❤️ from Berlin

[nayeembadhusha]

Can u make a video on different remoteType or library type with module federation
Like for example :
remoteType:"module" or library:{type:'module', name:Header'}

I dont want to expose my federated modules as globals or as an window object

[berkaygurcan]

I did not have the run and debug buttons, what can I do inside it?
