learn-angular-aot

A minimum project to learn aot with Angular5ngc and rollup. Also demonstrate how to import 3rd lib such as jQuery.

feature

This project use ngc to generate compiled Angular code and write it to disk, and then bundle the js code from disk. This make you be able to observe the code generate by angular compiler, and even edit it to see the difference! I think it is really helpful to understand & play with the "low-level machine code" of Angular.

command explain:

1. npm run compile: use ngc to compile the "angular syntax" into js. You can observe the output in compile_output/.
2. npm run rollup: rollup the whole application(including application code, angular framework, 3rd lib, except lazy-loading modules) into one file: serve/rollup-output.js.
3. npm run serve: copy the necessary files into the serve/ directory, and serve this folder with lite-server.
4. npm run clean: clean compile_output/ and serve/.
5. npm run aot: "npm run clean && npm run compile && npm run rollup && npm run serve".

emit control

• skipMetadataEmit in src\tsconfig.app.json determine whether or not Angular Compiler emit .metadata.json files.
• skipTemplateCodegen in src\tsconfig.app.json determine whether or not Angular Compiler emit .ngfactory.js and .ngstyle.js files.
• declaration in tsconfig.json determine whether or not TypeScript Compiler emit .d.ts definition files.
• sourceMap in tsconfig.json determine whether or not TypeScript Compiler emit .js.map sourcemap files.
