Builder API

Text

The Builder API is the Angular Tooling system to develop and interact with Builders and external tools, which can perform common tasks: Linting, Building...

Create a builder

import { 
  BuilderOutput, 
  createBuilder 
} from '@angular-devkit/architect';

export default createBuilder((options, context) => {
  return new Promise<BuilderOutput>(resolve => {
    resolve({ success: true });
  });
});

Use the builder

{
  "projects": {
    "builder-test": {
      "architect": {
        "touch": {
          "builder": "@example/command-runner:command",
          "options": {
            "command": "touch",
            "args": [
              "src/main.ts"
            ]
          }
        },
      }
    }
  }

Angular Schematics

Text

You can Build Your Own!

Create your own Schematic
npm i -g @angular-devkit/schematics-cli
schematics schmatic --name=indore
Use your own Schematic
ng new gdg-indore && cd $_
npm link /path/to/indore

schematics <path>:<schematic> --<option>=<value>

# schematics .:indore --tests=false

Ivy : Angular's new Renderer

Smaller Size

Simpler Stack Traces

Faster Compilation

Non-Breaking Changes!!

36kb

2.7kb

Ivy minified

Ivy compressed

Today (compressed – no zone.js)

10kb

Initial target

@kokkisajee

Differential loading

Reduce the payload size for all modern browsers.

Still support legacy browser and google crawler.

On By default in version 8.

# ./src/browserslist

> 0.5%
last 2 versions
Firefox ESR
not dead
not IE 9-11
# ./tsconfig.json

{
  "compilerOptions": {
    "target": "es2015"
  }
}

@kokkisajee

Try Ivy Today

npm i -g @angular/cli@next

# OR

ng update @angular/cli @angular/core --next

# OR for Angular version 8
ng new gdg-indore --enable-ivy
