Learn Figma, Firebase and Jasmine

OpenGraph images are the images you see when you paste a link into a social platform and it "unfurls" into an image, title, and description. This happens on Twitter, Discord, Slack, and many other platforms. This collection goes over everything from designing OpenGraph images in Figma, to implementing them in CodeSandbox, to returning headless browser screenshots from Netlify Functions, and finally using Cloudinary as a write-through cache. 

You will come away from this collection with the ability to ship an API that you can use on any of your sites, and also on-demand, that can generate images for not only OpenGraph unfurls, but also for Instagram, GitHub, and more. Using headless browsers with playwright to generate our images means we get full access to all the responsive power of CSS and all the logical power of JS to handle layout, importing assets like pngs, choosing different fonts, and more.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Figma is a collaborative prototyping tool that allows you to responsively design your applications, with resolution presets for all of the most popular devices. In this course, we will explore the fundamentals of Figma’s toolset that you can use for various design functions. 

We will start from scratch, then walk through scenarios you may encounter when designing a website or application. We will cover building reusable designs — known as “components” in Figma — all the way up to prototyping your designs to show screen transitions and animations between state. 

By the end of the course, you will understand the basics of Figma so you can use it to your advantage when building your next app or website.

Design, prototype, and gather feedback all in one place with Figma.

The Beginner's Guide to Figma

Protect yourself from unexpected charges by learning how to use Firebase emulators. 

By using Firebase emulators you no longer have to create a second dev firebase project to avoid using production data. You also don't run the risk of having a cloud function crash and run up a huge bill.

In this course, you'll learn how to set up and use Firebase's authentication, function, and Firestore emulators. You will also learn how to safely set up Cloud Function emulation, import seed data into your emulators, and disable the emulators in production.  

By the end of this course, you'll be able to confidently set up a safe environment for testing in your own applications!

Local App Development with the Firebase Emulator Suite

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

In this lesson Trevor looks at testing AngularJS controllers with scope inheritance with Jasmine and test spies.

Testing Controllers With Dependencies

The Firebase Forge provides a convenient GUI for visualizing and manipulating your data in real-time. Be sure to check out [this lesson](https://egghead.io/lessons/angularjs-get-started-with-firebase-and-angularfire) for getting Firebase setup.

Custom Jasmine Matchers are a great way to keep your AngularJS Unit Tests clean and tidy. We want to make expectations **readable** and express the intent of the test. Custom matchers help to accomplish this.

Custom Jasmine 1.3 Matchers

When using Firebase collections in your AngularJS application, you have access to a handy set of events emitted by the collection when changes in your data occur. Be sure to check out the [first lesson](https://egghead.io/lessons/angularjs-get-started-with-firebase-and-angularfire) in this series for the project source code.

Firebase provides a real-time syncing backend for your AngularJS applications in very few lines of code. In this lesson, you'll learn how to get started integrating it into your app.

Get Started with Firebase and AngularFire

Data has relationships, and Firebase allows you to define those relationships in your AngularJS applications.

In this lesson John shows some tricks for speeding up your test suite. He digs into some handy features of WebStorm, including the *ddescriber* plugin, as well as some alternative methods for Jasmine for selectively running your tests.

Firebase has several ways to provide authentication for your AngularJS application. In this lesson, Lukas will look at the most basic email/password approach.

Firebase Basic Authentication Part 1

One of the beautiful things about dependency injection in your AngularJS apps is the ability to replace dependencies in your unit tests. In this lesson Trevor looks at how to configure Jasmine spies as injectable replacements for dependencies for testing.

Testing is a first class citizen in AngularJS. It is at its heart and soul. This lesson demonstrates using Karma to write a simple unit test for a Filter.

Unit Testing AngularJS

Unit testing a React component using Webpack and Jasmine, can involve slow and repetitive tasks when confirming that tests are passing when your code changes. For example, manually running commands instructing webpack to compile code plus refreshing the browser. This lesson demonstrates how to speed up your development time by automating these tasks using webpack-dev-server.

Reloading React component tests using webpack-dev-server

Using Jasmine, this lesson will look at testing an AngularJS service.

Testing a Service

Authenticating with Firebase creates a 24 hour session for the user. This allows you to fetch the current session for the user, as well as logout the user and destroy the session.

In this video, you will learn how to create frames (i.e. layouts) in Figma using the "frame" tool. This will allow you to get up and running quickly using pre-defined sizes.

Create a Mobile, Tablet and Desktop Frame in Figma

In this lesson, you will learn how to build a component in Figma, which is the equivalent to a "symbol" in Sketch. It's essentially a reusable piece of design. This will allow you to work more efficiently when designing your app.

Build Reusable Designs with Figma Components

In this lesson, you will learn how to use Figma's ellipse and pen tool to draw a simple clock icon. This will show you how to create vector-based graphics for your websites and apps.
