Hey there friends. So yesterday I was just a fanboying I guess aboutPrisma. If you haven't heard of Prisma, it is a Oh what does that? It's ORN, I can't remember what what the word for that is but it interfaces between you and a backend database. So it supports post-grass and SQLite my sequel and a MongoDB support is coming. So yeah, just so you have a database and you tell it what database what kind of,Database you're hitting and how to connect to it or what the connection URL is. And then it

https://github.com/johnlindquist/kit/discussions/310 https://www.scriptkit.com/ Hello friends. So this morning, I finished something that I was working on a little bit yesterday. It's a script kit script to call Cloud Nary upload which allows me to very easily upload images to my cloud nary account. It uses the cloud nary API and yeah, I just need a couple of environment variables and and you can use this too. You get script kit, you can copy the same script. And yeah, you just need a couple

Avoid Hasty Abstractions: Hooks edition

3 Minutes with Kent ·

2021/06/07

Hello friends, so I wanted to talk today about whether or not you should make a custom hook for everything. So a few days ago, maybe last week there was this thing going around where people were recommending that you never ever use the react built-in hooks inside of a component, you always extract it to a custom hook. This is terrible advice. Don't do that at all. So the way that I think about hooks in React is the they're basically functions that have the,Only special distinction of being functions

https://stackoverflow.com/a/46780568/971592 Hello there friends. Sorry, it's been a little bit of a break but I was working on something and I wanted to measure how fast it was but yeah and so I'm gonna use the Chrome DevTools profiling performance tab to profile it. And it's always so frustrating to like try and find the part of the code that you're trying to profile in that flame graph. It's really kind of a confusing area. And I remembered that there's the performance mark API and so you have the

Hello there friends. Welcome to June I am thinking about Postgres and Prisma and that sort of thing a lot lately because I'm working on my website and doing that sort of thing and one tip that I have for you if you ever do database sort of things is try to make sorry to make your data as. As restrictive as possible. Early on as as you're trying to make things. So like make things if you're like, I don't know if there should be a required field or not make it required. If you're this is an enum but

https://kentcdodds.com/blog/fix-the-slow-render-before-you-fix-the-re-render https://kentcdodds.com/blog/colocation https://epicreact.dev/improve-the-performance-of-your-react-forms Hello there friends. So today somebody shared a lightbri with me and I assumed that it was just a library to help you track rerenders. But it turns out it's like a state management library and that helps you avoid rerenders but my initial reaction and thought about tracking re-renders is the tools like that. I think lead

Keep related utilities in a single file

3 Minutes with Kent ·

2021/05/28

Hello there friends, so I was thinking this morning about utilities and you know these little utility functions that we write and we put it in like a utils modular or something and sometimes when we're running these we want to split things out to make it just.Easier to manage or something and and it's just kind of a natural thing at least for me to want to split things out into individual files, so each utility is in its own file, you know, if it's just a single line or something. I typically just

Good morning or afternoon or evening friends, I wanted to talk today about a saying that my wife has I think when my kids grow up they're gonna remember my mom always used to say this and and so what she says is we'll cross that bridge when we come to it now, of course this isn't like an original saying but she just says it a lot and what she's saying is that she doesn't want to make these decisions right now or use up the mental energy to decide whether or not. She wants to let the kids do a

Hello there friends So this morning I was just thinking about this little tip that I share with you. It's pretty quick. In my global git ignore, which is located in my home directory dot get ignore underscore global. I have a couple of things in here that I wanted to shout out and specifically this morning. I was thinking about my ignored global good ignore. So I am I have a two rules that will ignore any files that or any directories that end in dot ignored in any files that include dot ignored dot

Hello friends so I mostly recording this one so that I can hopefully not forget it because I was working with doctor yesterday and I don't work with Docker a lot but I'm kind of thinking about in the next version of Epic React. I want to take the application that we build and make it even more real world. We're going to jump off of Create. React app and use Remix. Don't worry, they're probably going to have some sort of free tier or a trial version or something. So, I'm not going to force people to

2021/05/24

Hello there friends, so I've just been thinking about incentives and companies and and the yeah, like what what motivates people to have different opinions and stuff like that. And I want to use myself as an example here because I think it's a there's a lot of nuance with the way that we kind of automatically think that people are have ulterior motives. So, I created epic react to teach people how to learn react. And so my question is did did I create epic react?And then say hey everybody it's React

Hey there friends. Have you heard of progressive enhancement or progressive web apps? Well, I thought of a real world thing that kind of resembles what this actually means and what it doesn't. So, you know how like there's all these memes of like I got a smart thermostat and now it's broken because my internet went down or something like that and so now I'm like steaming hot like why did I do this and and we have the same sort of thing with my watch and so I have a smartwatch.

TypeScript is testing

2021/05/20

https://kcd.im/trophy https://kentcdodds.com/blog/eliminate-an-entire-category-of-bugs-with-a-few-simple-tools TypeScript is tests. Tests are type script. So type script is just a way to give yourself more confidence. Sure, it helps you in your workflow, it makes you a faster as you're developing because you have autocomplete and stuff like that. And testing does the same thing as well as you refactoring, you know that you didn't break anything you get a much faster feedback when you you're running

TypeScript: Why I prefer `Array` over `Type[]`

3 Minutes with Kent ·

2021/05/19

Good morning or afternoon or whatever it is for you friends, it's morning for me. I wanted to talk about how I type a raise in TypeScript, so there are two ways that I'm aware of that you can type an array and of course I guess there are a couple ways depending on what type of an array you want to make but just like a regular array you can either specify the type and then immediately thereafter with no space a open and closing bracket like the the syntax for an array and the alternative is there is

Don't bundle and minify your published npm packages

3 Minutes with Kent ·

2021/05/19

https://twitter.com/kentcdodds/status/1394420201542668289?s=20 So the other day I tweeted about how I really want people to stop minifying and bundling what they send to NPM. And just to clarify I it's fine if you want to minify and bundle as one of the things you distribute as part of your package, but it shouldn't be the only thing and there are a couple of reasons and what I do for my packages is I actually do have a UMD module that is bundled and I have a minified version of that as well. So we

Sharing server/client validation logic with @remix_run

2021/05/17

Hey friends, so I'm working on this little remix app and just something about remix that I just this so cool the fact that your server and client side code run is written in the same file if in case you didn't know that that's that's what you do and it's really cool for validation so you can start by validating just a hundred percent on the server and remix makes it quite nice to be able to do that and that's where your validation should absolutely. 100% go by default that's like if you're gonna do

Tests the tests by making them fail

https://kentcdodds.com/blog/make-your-test-fail Hello there friends. I'm just driving now. I was thinking about a blog post that I wrote a while ago. I think it was called break your tests or something like that, but the idea is that it's just really easy to write a test that passes and so you feel really good about it this this especially happens if you're testing after you've already implemented something if you're doing TDD this is maybe less of a problem, but it's really easy to write a test

I was working on something that I'm working on for the new website where you can submit a recording of a question and then I'll be able to answer it's gonna be really cool but it's all like in browser recording stuff and lots of what I was testing was like required me to have to record something and then to continue on through the the work.

Hello friends So today a friend of mine on the KCD Discord is named Rupert. I'm not sure. I'm pretty sure that's how you say their name. But I created their very first poll request for open source. I wasn't aware it's the first poll request but they did a great job. And it was for the KCD Discord bond. And so the discord has a lot of cool things you can do with it and one of them is they're a bunch of commands that you can give. One of those commands is the thanks command where you can give somebody

How to prepare for meetings that convince people

2021/05/12

So let's say that you want to convince your coworkers to try a new tech or something like a new library or whatever and you think it's a really good idea but people aren't convinced. So what typically happens is you want to prepare a couple of ideas and stuff and bring it to a meeting and say, okay, here's here's what I think and why I think this is a good idea. And then people will present their reasons why they they don't think it's a good idea. And people may come to the meeting kind of
