files + stage area
Modifies trees instead of the filesystem directly
Dry runs Reusability Extensibility That allows for
Creating schematics
npm i -g @angular-devkit/schematics-cli Install it
schematics blank --name=my-component Generate a blank schematic
Rules
z import { Rule, SchematicContext, Tree } from '@angular-devkit/schematics'; export
function myComponent(options: any): Rule { return (tree: Tree, _context: SchematicContext) => { return tree; }; }
z import { Rule, SchematicContext, Tree } from '@angular-devkit/schematics'; export
function myComponent(options: any): Rule { return (tree: Tree, _context: SchematicContext) => { return tree; }; }
z import { Rule, SchematicContext, Tree } from '@angular-devkit/schematics'; export
function myComponent(options: any): Rule { return (tree: Tree, _context: SchematicContext) => { tree.create(options.name || 'hello', 'world'); return tree; }; } Create and modify files
z import { Rule, SchematicContext, Tree, chain, externalSchematic } from
'@angular-devkit/schematics'; export function myComponent(options: any): Rule { return (tree: Tree, _context: SchematicContext) => { tree.create(options.name || 'hello', 'world'); return chain(tree, externalSchematic(...)); }; } Chain external schematics
Collections
z { "$schema": “.../@angular-devkit/schematics/ collection-schema.json", "schematics": { "my-component": { "description":
"A blank schematic.", "factory": "./my-component/index#myComponent" } } } Schematics collection collection.json
npm run build Build and test it schematics .:my-component --name=test
--dry-run=false
node --inspect-brk $(which schematics) .:myComponent --name=test Debug it
ng new myapp Use it with the CLI npm link
$PATH_TO_my-component ng g my-component:my-component someName
