• Learned how to make a Chrome extension (did one actually)
• Learned that Chrome extensions will be deprecated in the near future

[Cole Walker]

Vue and CommonLISP. Both are cool!

[Nick Taylor]

Noice!

[Patrik Kiss]

Learned the basics of VueJS! I'm already making my first app

[Bugsy Sailor]

I learned a PHP class to generate PDF barcodes from the Square API to generate barcode labels for my retail shop.

[Jérémie Astor]

I made my first typescript github actions, and in another one, I use awk, which for some reasons I neglected before.

[Irem Kaya]

I learnt to incorporate different React Native libs with each other + with React Hooks!
Also learnt a bit of GraphQL for making a schema for a custom api :)

[Zaynaib (Ola) Giwa]

Finally learned how to lift up state in React. T_T I'm still a little bit confused about the subject but at least I got my app to work.

[Irem Kaya]

What are you confused about? Is there anything I can help you with? Been coding with React Native + React for a year now :)

[Asha Balasubramaniam]

Got some time to clean up my bash prompt by adding a random emoji to it. This was way more fun that I thought it would be.. (also there’s a bug here that’s fixed in a follow up commit 😅)

[Aman]

Developed an application on Springboot. Exposed rest end points. Created automated tests using Postman. It was a fun excercise.

[Eyituoyo Donald Okegbe]

Finally understood a lot on react and got my hands dirty with it. Hoping to learn more and go down further

[Nick Taylor]

Noice!

This week I learned more about the Net Core Request Pipeline.
Especially, that when using a controller with non default ActionResult return type, like for example BadRequest(), that these ActionResults will get wrapped in another ActionResult, which makes unit testing kind of tedious. E.g.:

        // controller method
        [Route("{id:int}")]
        [HttpGet]
        [ProducesResponseType(StatusCodes.Status200OK)]
        [ProducesResponseType(StatusCodes.Status404NotFound)]
        public async Task<ActionResult<Author>> GetOneById(int id)
        {
            Author result = await _authorService.GetById(id);

            if (result != null)
            {
                return result;
            }
            else
            {
                return NotFound();
            }
        }

        // tests
        [Fact(DisplayName = "Should return correct author by id")]
        public async Task Should_Return_Author_By_Id()
        {
            // arrange
            var expected = fixture.authorList.Where(author => author.Id == 1).FirstOrDefault();

            // act
            var result = await controller.GetOneById(1);

            // assert
            Assert.IsType<ActionResult<Author>>(result);
            Assert.Equal(expected, result.Value); // Using Value since ReturnType is ActionResult<Author>, so we need to access the value
        }

        [Fact(DisplayName = "Should return NotFound()")]
        public async Task Should_Return_Author_NotFound()
        {
            // act
            var result = await controller.GetOneById(999);

            // assert
            Assert.Null(result.Value);
            Assert.IsType<ActionResult<Author>>(result); // check method return type matches
            Assert.IsType<NotFoundResult>(result.Result); // check actual return is as expected
        }

Mario approves. He's just not sure which pipeline to jump into 😉

[Odilon Jonathan Kröger]

I've learned about writing example tests on Golang, to show the code on godoc.
I also learned how to deploy an application on GCP App Engine. :D

[Astrit]

Today I learned about twitter.com/visualizevalue hands down the best twitter account to follow 🤘🚀

[Adam Crockett 🌀]

That I am more versatile than I think I am.

[Dzhavat Ushev]

I learnt how to make a script to kill a port (to stop a localhost server) by calling an npm command that runs a js file that runs a PowerShell script. Works like magic.

It was my first time touching a PowerShell script so this gave me extra points :D
