Angular compiler components é um projeto para compilar componentes em angular. Baseado no angular-library-builder

What is Angular Library Builder (nglb)?

It's a CLI Tool to build Angular (2+) libraries ready to be published to npm.

What problem is Angular Library Builder (nglb) trying to solve?

At the moment there is no official documentation/guidelines on how to build and publish Angular (2+) components/libraries/services/modules to npm. Angular Library Builder (nglb) is trying to solve this in the easiest way possible.

How does Angular Library Builder (nglb) solve this?

• If it is a component, inlines html template file into the component as a string, replacing templateUrl with template
  • In the inlining process nglb also minifies html using html-minifier
• If it is a component, inlines scss/sass/css file(s) into the component as a string, replacing stylesUrls with styles. It uses:
  • node-sass to compile scss/sass file(s)
  • autoprefixer to improve browser compatibilty
  • csso to minimize/optimize your css
• Finally, it compiles your resulting typescript files with all your html and css inlined, using @angular/compiler-cli (ngc), creating *.d.ts, *.js, *.js.map, *.metadata.json files

Getting Started

Install the angular-compiler-components command

npm install --save-dev angular-compiler-components

How to use angular-compiler-components?

Add angular-compiler-components (nglb) script, main and types to package.json:

"main": "./lib-dist/your-main-file.js",
"types": "./lib-dist/your-main-file.d.ts",
"scripts": {
  "build:library": "nglb --rootDir src/lib --outDir lib-dist"
}

or

"main": "./lib-dist/your-main-file.js",
"types": "./lib-dist/your-main-file.d.ts",
"scripts": {
  "build:library": "angular-compiler-components --rootDir src/lib --outDir lib-dist"
}

Now, in your project root:

npm run build:library

Congratulations! Your library is available in lib-dist folder ready to be published to npm.

To publish your new library to npm, execute the following command in your project root:

npm publish

Options that angular-compiler-components supports

option (argument)	description
--rootDir	Specifies the root directory of input files. Example: nglb --rootDir src, [required]
--outDir	Redirect output structure to the directory. Example: nglb --outDir dist, [required]
--tsconfig	Possibility to extend/override properties in default tsconfig-ngc.json. Example: nglb --tsconfig path/to/your/override-tsconfig-ngc.json
--help (-h)	Print help message

How to change angular-compiler-components tsconfig-ngc.json default properties?

Sometimes the defaults aren't good enough for everybody.

Example

Let's imagine that you want to change slightly the build process:

• change the default "target" from "es5" to "es2015"
• add a new property, for example, "noImplicitAny": true,

To acomplish this create a file called, for example, override-tsconfig-ngc.json in your project root. Your override-tsconfig-ngc.json file can be something like:

{
  "compilerOptions": {
    "target": "es2015",
    "noImplicitAny": true
  }
}

Then, you invoke nglb like this:

nglb --rootDir path/to/your/source --outDir path/to/dist --tsconfig override-tsconfig-ngc.json
