## ember-cli-typescript

This guide is designed to help you get up and running with TypeScript in an Ember app.

{% hint style="warning" %}
**This is *****not***** an introduction to TypeScript *****or***** Ember. Throughout this guide, we’ll link back to** [**the TypeScript docs**](https://www.typescriptlang.org/docs/home.html) **and** [**the Ember Guides**](https://guides.emberjs.com/release/) **when there are specific concepts that we will not explain here but which are important for understanding what we’re covering!**

To get started, check out the instructions in [Getting Started: Installation](https://docs.ember-cli-typescript.com/installation)

* If you're totally new to using TypeScript with Ember, start with [TypeScript and Ember](https://docs.ember-cli-typescript.com/ts).
* Once you have a good handle on the basics, you can dive into the guides to working with the APIs specific to [Ember](https://docs.ember-cli-typescript.com/ember) and [Ember Data](https://docs.ember-cli-typescript.com/ember-data).
* If you're working with legacy (pre-Octane) Ember and TypeScript together, you should read [the Legacy Guide](https://docs.ember-cli-typescript.com/legacy).
* Looking for type-checking in Glimmer templates? Check out [Glint](https://typed-ember.gitbook.io/glint/).

### Why TypeScript?

What is TypeScript, and why should you adopt it?

> TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.\

TypeScript lets you build *ambitious web applications* with confidence—so it’s a perfect fit for Ember apps!

* Enjoy API docs… that are always up-to-date.
