Npm i -save-dev chai mocha ts-mockito ts-node replace generated "scripts" section in package. npm i -save typescript discord.js inversify dotenv reflect-metadata Then, let’s install our dependencies and dev dependencies (those which are only needed for the tests). Strongly-typed function component props One of the best parts of using Typescript with React is the ability to use strongly-typed component props. You can safely just press Enter for all questions (or provide some information if you want). I will show you four of the best features offered by TypeScript, but keep in mind that there is a lot more it can do from React. This will open an interactive wizard, which will set up the package.json file. Note: You could also use yarn for that, but let’s stick to npm for brevity. Then, enter it and create a new Node.js project by running: npm init Bonus: Mongoose and MongoDB, in order to write an integration testįirst, let’s create a new directory called typescript-bot.Testing libraries: Mocha, Chai, and ts-mockito.
InversifyJS, a dependency injection framework.Discord.js, a wrapper for the Discord API.Instead, we will simply demonstrate TypeScript best practices as we walk through how to make a Discord bot from scratch, hook up tests and DI, and create a sample service. In this TypeScript tutorial, we won’t cover TypeScript basics directly, except for compilation. We can apply these two techniques to JavaScript development by leveraging TypeScript and the dependency injection (DI) design pattern, respectively. Types and testable code are two of the most effective ways of avoiding bugs, especially as code changes over time.
