Webpack configuration modifier for @angular/cli
This package provides an opportunity to modify @angular/cli project’s webpack configuration without “ejecting”.
For angular 6/7:
$ npx -p @angular/cli ng new my-project && cd my-project # create new Angular CLI project
$ npm i -D ngw # installing an improved cli-eject
$ ./node_modules/.bin/ngw --set-up # run via terminal in project root
Set up went successfully!
For angular 5 use npm i -D ngw@angular5
Last command installation (ngw —set-up) makes three things:
1) Changes scripts in package.json that starts from ng
to ngw
2) Creates file ngw.config.ts
in project root where you can redefine webpack.Configuration
used by @angular/cli
3) Sets compilerOptions.module = "commonjs"
property in tsconfig.json
So just make changes to the webpack config in appeared ngw.config.ts
You may like to do npm i -D @types/webpack
for better experience.
This little piece of code in your ngw.config removes unused selectors from your CSS:
const PurifyCSSPlugin = require('purifycss-webpack');
const path = require('path');
const glob = require('glob');
export default function(config) {
config.plugins.push(
new PurifyCSSPlugin({
paths: glob.sync(path.join(__dirname, '**/*.html'))
})
);
return config;
}
You may like to debug your configuration.
This can be done with ndb package.
1) Make sure that your development environment meets the requirements of ndb
2) npm i -g ndb
3) Add debugger
keyword in ngw.config.ts
4) ndb npm run start
const isProduction = process.argv.indexOf('--prod') !== -1;
export default function(config, options) {
//common config modification
...
config = isProduction
? productionModificationsMerged(config)
: devModificationsMerged(config);
}
...
}
