What is Angular Ivy?

Angular Ivy is a new rendering engine for Angular. You can choose to opt in a preview version of Ivy from Angular version 8.

1. You can enable ivy in a new project by using the --enable-ivy flag with the ng new command

ng new ivy-demo-app --enable-ivy

2. You can add it to an existing project by adding enableIvy option in the angularCompilerOptions in your project's tsconfig.app.json.

{
"compilerOptions": { ... },
"angularCompilerOptions": {
"enableIvy": true
}
}
