In this video, the author demonstrates how to use React and TypeScript to create a simple user interface. They test a failing test and then add a url parameter to the test, which passes. Next, they add a hello() function to the test and check that it works. In the second part of the video, the author demonstrates how to use React and TypeScript to create a simple web application. He first shows how to create a simple React component, and then how to use TypeScript to declare the types of the component's parameters and state. He then demonstrates how to use React and TypeScript to create a fallback component that handles cases where the main component fails. Finally, he shows how to use React and TypeScript to create a user interface that displays the fallback component and the user's avatar.

00:00:00 In this video, React and TypeScript developer Chris Luna discusses a basic avatar component he plans to create using React and TypeScript. The component will be inspired by GitHub, and will provide a hands-on introduction to React and TypeScript.
00:05:00 In this video, the creator discusses how to use React and TypeScript to build an avatar component. They explain that the component should take a url as an input and should be optional. If no url is provided, the default avatar photo should be shown.
00:10:00 In this video, Odasio discusses the pros and cons of using React and TypeScript for building web applications. He shows how to create a new project with either language and then discusses common issues developers run into. He also demonstrates how to use keyboard shortcuts in both languages.
00:15:00 In this video, React and TypeScript developer Darren Cool demonstrates how to use TypeScript to write tests for a React component. First, they create a new React component and write some tests for it. Then, they add a callback function to the component and write another set of tests. Finally, they use TypeScript's getByAltText() function to render the component with a fallback image if a URL is not provided.
00:20:00 In this video, the author shows how to use React and TypeScript to build a simple application. First, they create a test file and then they create a new file, Avatar.tsx, to contain their Avatar function. Next, they get the auto-import for Avatar and then they save the file. Finally, they run the tests and fix a typescript error.
00:25:00 In this video, the author discusses how to build a React component using TypeScript and how to use interfaces to declare the public API. They also mention using ts doc to document the component. When hovering over an avatar prop, the author found that this did not work as expected and found out that it was because ts dock had been removed from the React ecosystem.
00:30:00 In the second part of this video, the author shows how to use React and TypeScript to create a simple user avatar component. While the author initially seems to be successful, they later realize they have forgotten to add a quote sign to their keyboard layout and the component fails to render.
00:35:00 In this video, the author explains how to use React and TypeScript to build a simple user interface. They test a failing test and then add a url parameter to the test, which passes. Next, they add a hello() function to the test and check that it works.
00:40:00 In the second part of this video, the author demonstrates how to use React and TypeScript to create a simple web application. He first shows how to create a simple React component, and then how to use TypeScript to declare the types of the component's parameters and state. He then demonstrates how to use React and TypeScript to create a fallback component that handles cases where the main component fails. Finally, he shows how to use React and TypeScript to create a user interface that displays the fallback component and the user's avatar.
00:45:00 In this video, the presenter discusses how React and TypeScript can be used to create a basic website. He shows how to create a ref and use it to reference a remote image, and then how to handle the case where the remote image fails. He also shows how to add a background image to the avatar container with CSS.
00:50:00 In this video, React and TypeScript developer Sean Larkin demonstrates how to use a fetch call with a promise to set the fallback URL in case the requested image is not found.
00:55:00 In the first part of the video, the presenter shows how to create a basic React and TypeScript application. In the second part, they discuss how to handle errors and how to set the URL for an avatar.

01:00:00 - 01:40:00

In this video, the presenter demonstrates how to use React and TypeScript to build a simple web application. They discuss how to import React, use avatar URLs, and fetch resources. They then run into an error and discover that fetch is not defined in a browser context. They investigate and find that the error is caused by the fact that they are running the tests in a node environment instead of in a browser. They conclude that it may just be fetch that is missing from the code and that they should try to find a way to mock it.

01:05:00 In this video, the presenter discusses how to build web applications with React and TypeScript. They note that, in order to use TypeScript with React, you need to configure v-test to use jsdom. If you don't do this, then fetch won't be available and your application will not work. They then show an example of how to use TypeScript with React and Document. Finally, they discuss how to avoid errors in your application by restarting it if it fails.
01:10:00 In this second part of the video, the author discusses how to use React and TypeScript with a keyboard. He explains that he likes to use two keys to get to his code layer - one for enter and one for arrows - and that he is slower than he used to be. He also talks about how he uses a media layer to pause and increase the volume of music. Finally, he shows how he uses a different keyboard shortcut on the mac layer to zoom in and out.
01:15:00 In this video, the presenter shows how to use React and TypeScript to build a simple web application. They discuss how the React and TypeScript code works together, and how to check that the code is working correctly. They also discuss how to handle errors and how to retry a failed task.
01:20:00 In the second part of this tutorial, the author demonstrates how to build a basic React app using TypeScript and the React Router. If an image is not valid, the app sets the status code to 500 and returns the image. If the image is valid, the app sets the status code to 400 and renders the url.
01:25:00 In this video, the speaker demonstrates how to build a simple React app with TypeScript and React. They discuss how to create an async component and use query by alt text to test whether it works. They also show how to add css and a cat image to the app. However, when they try to use the fallback image, it fails. The speaker then explains that something about their logic is off, and they fix it by adding a code comment for the fallback image. This makes them feel relieved because before, they were unsure if React or a React testing library was necessary.
01:30:00 The author is testing a component that renders a fallback image if a URL is a 404. They are passing in a bad URL, and the component is expecting the source to be the fallback image. When they try to debug the rendered output, they realize that the order of get calls doesn't seem to matter.
01:35:00 In this video, the presenter demonstrates how to use the wait for React Testing Library API to wait for an element to appear on the screen. They also discuss how to use fine by source to wait until something changes.
01:40:00 In this video, the presenter shows how to build a simple React app using TypeScript and React. They first create a simple React component and then add it to a page. Next, they add a TypeScript file to the project and add some code to it. Finally, they add a React component to the TypeScript file and test it. They find that adding the Avatar component to the TypeScript file works, but they have to wait for it to load before they can test it. They then add a tests file to the project and test it.
