# Opting into Angular Ivy
|
|
|
|
Ivy is the code name for Angular's [next-generation compilation and rendering pipeline](https://blog.angular.io/a-plan-for-version-8-0-and-ivy-b3318dfc19f7). Starting with Angular version 8, you can choose to opt in to start using Ivy now, and help in its continuing develpment and tuning.
|
|
|
|
|
|
## Using Ivy in a new project
|
|
|
|
To start a new project with Ivy enabled, use the `--enable-ivy` flag with the [`ng new`](cli/new) command:
|
|
|
|
```sh
|
|
ng new shiny-ivy-app --enable-ivy
|
|
```
|
|
|
|
The new project is automatically configured for Ivy. Specifically, the enableIvy option is set to `true` in the project's `tsconfig.app.json` file.
|
|
|
|
|
|
## Using Ivy in an existing project
|
|
|
|
To update an existing project to use Ivy, set the `enableIvy` option in the `angularCompilerOptions` in your project's `tsconfig.app.json`.
|
|
```json
|
|
{
|
|
"compilerOptions": { ... },
|
|
"angularCompilerOptions": {
|
|
"enableIvy": true
|
|
}
|
|
}
|
|
```
|
|
|
|
To stop using the Ivy compiler, set `enableIvy` to `false` in `tsconfig.app.json`, or remove it completely.
