We want to use bootstrap 4 (4.0.0-alpha.2) in our app generated with angular-cli 1.0.0-beta.5 (w/ node v6.1.0).
After getting bootstrap and its dependencies with npm, our first approach consisted in adding them in angular-cli-build.js
:
'bootstrap/dist/**/*.min.+(js|css)',
'jquery/dist/jquery.min.+(js|map)',
'tether/dist/**/*.min.+(js|css)',
and import them in our index.html
<script src="vendor/jquery/dist/jquery.min.js"></script>
<script src="vendor/tether/dist/js/tether.min.js"></script>
<link rel="stylesheet" type="text/css" href="vendor/bootstrap/dist/css/bootstrap.min.css">
<script src="vendor/bootstrap/dist/js/bootstrap.min.js"></script>
This worked fine with ng serve
but as soon as we produced a build with -prod
flag all these dependencies disappeared from dist/vendor
(surprise !).
How we are intended to handle such scenario (i.e. loading bootstrap scripts) in a project generated with angular-cli ?
We had the following thoughts but we don't really know which way to go...
use a CDN ? but we would rather serve these files to guarantee that they will be available
copy dependencies to dist/vendor
after our ng build -prod
? But that seems like something angular-cli should provide since it 'takes care' of the build part ?
adding jquery, bootstrap and tether in src/system-config.ts
and somehow pull them into our bundle in main.ts
? But that seemed wrong considering that we are not going to explicitly use them in our application's code (unlike moment.js or something like lodash, for example).
IMPORTANT UPDATE: ng2-bootstrap is now replaced by ngx-bootstrap
ngx-bootstrap supports both Angular 3 and 4.
Update : 1.0.0-beta.11-webpack or above versions
First of all check your angular-cli version with the following command in the terminal:
ng -v
If your angular-cli version is greater than 1.0.0-beta.11-webpack, then you should follow these steps:
Install ngx-bootstrap and bootstrap:
npm install ngx-bootstrap bootstrap --save
This line installs Bootstrap 3 nowadays, but can install Bootstrap 4 in the future. Keep in mind ngx-bootstrap supports both versions.
Open src/app/app.module.ts and add:
import { AlertModule } from 'ngx-bootstrap';
...
@NgModule({
...
imports: [AlertModule.forRoot(), ... ],
...
})
Open angular-cli.json (for angular6 and later file name changed to angular.json ) and insert a new entry into the styles
array:
"styles": [
"styles.css",
"../node_modules/bootstrap/dist/css/bootstrap.min.css"
],
Open src/app/app.component.html and add:
<alert type="success">hello</alert>
1.0.0-beta.10 or below versions:
And, if your angular-cli version is 1.0.0-beta.10 or below, then you can use below steps.
First, go to the project directory and type:
npm install ngx-bootstrap --save
Then, open your angular-cli-build.js and add this line:
vendorNpmFiles: [
...
'ngx-bootstrap/**/*.js',
...
]
Now, open your src/system-config.ts then write:
const map:any = {
...
'ngx-bootstrap': 'vendor/ngx-bootstrap',
...
}
...and:
const packages: any = {
'ngx-bootstrap': {
format: 'cjs',
defaultExtension: 'js',
main: 'ngx-bootstrap.js'
}
};
