ngx-bootstrap

What is ngx-bootstrap?

ngx-bootstrap is a popular Angular library that provides Bootstrap components powered by Angular. It allows developers to use Bootstrap's UI components in their Angular applications with ease, offering a wide range of features and customization options.

What are ngx-bootstrap's main functionalities?

Alerts

The Alerts component allows you to display different types of alert messages such as success, info, warning, and danger. This is useful for providing feedback to users.

<alert type="success">Success Alert</alert>

Modals

The Modals component allows you to create and manage modal dialogs. This is useful for displaying additional information or forms without navigating away from the current page.

<button type="button" class="btn btn-primary" (click)="openModal()">Open Modal</button>
<ng-template #template>
  <div class="modal-body">
    <p>Modal content goes here.</p>
  </div>
</ng-template>

Datepicker

The Datepicker component provides a user-friendly way to select dates. It supports various configurations and customizations to fit different use cases.

<input type="text" class="form-control" bsDatepicker>

Tabs

The Tabs component allows you to create tabbed interfaces. This is useful for organizing content into separate sections that can be easily navigated by users.

<tabset>
  <tab heading="Tab 1">Content of Tab 1</tab>
  <tab heading="Tab 2">Content of Tab 2</tab>
</tabset>

Tooltips

The Tooltips component provides a way to display additional information when users hover over or focus on an element. This is useful for providing contextual help or explanations.

<button type="button" class="btn btn-secondary" tooltip="Tooltip text">Hover me</button>

Getting Started

ngx-bootstrap contains all core (and not only) Bootstrap components powered by Angular. So you don't need to include original JS components, but we are using markup and CSS provided by Bootstrap.

Supporting NGX-Bootstrap

ngx-bootstrap is an Open Source (MIT Licensed) project, it's an independent project with ongoing development made possible thanks to the support of our awesome backers. If you also would like to show support or simply give back to Open Source community, please consider becoming a backer sponsor of ngx-bootstrap on OpenCollective

All donated funds are managed transparently on OpenCollective and will be used solely for compensating work and expenses for contributors. Valor Software employees and contractors are not eligible to use these funds.

Installation instructions

Method 1

Install ngx-bootstrap from npm:

npm install ngx-bootstrap --save

Add needed package to NgModule imports:

import { TooltipModule } from 'ngx-bootstrap/tooltip';

@NgModule({
  ...
  imports: [TooltipModule.forRoot(),...]
  ...
})

Add component to your page:

<button type="button" class="btn btn-primary"
        tooltip="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Simple demo
</button>

You will need bootstrap styles:

• Bootstrap 3

<!-- index.html -->
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">

• Bootstrap 4

<!--- index.html -->
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet">

Method 2

Use the Angular CLI ng add command for updating your Angular project

ng add ngx-bootstrap

Or use ng add to add needed component (for example tooltip)

ng add ngx-bootstrap --component tooltip

Add component to your page:

<button type="button" class="btn btn-primary"
        tooltip="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Simple demo
</button>

Setting up the bootstrap version manually

Sometimes, your project might contain some library that could interfere with the bootstrap framework, or you might have a customized version of bootstrap. The consequence is that the process of determining bootstrap version might be failed, which can break the UI. In that case, we can still set the bootstrap version manually in the bootstrapping component (i.e. AppComponent):

import { setTheme } from 'ngx-bootstrap/utils';

@Component({...})
export class AppComponent {
  constructor() {
    setTheme('bs3'); // or 'bs4'
    ...
  }
}

• npm run build

To update your fork and prepare it for local usage:

• git pull upstream development
• rm -rf node_modules
• npm install
• npm run build

To run the demo:

• npm run demo.serve // to serve local demo. This is for testing only, without watchers.

For local development run:

• npm run build.watch // in first terminal
• ng serve // in second

If you want to run the demo with Angular Universal:

Compatibility

The only two dependencies are Angular and Bootstrap CSS. Here is the versions compatibility list:

ngx-bootstrap	Angular	Bootstrap CSS

4.x.x	6.x.x - 7.x.x	3.x.x or 4.x.x
3.x.x	6.x.x - 7.x.x	3.x.x or 4.x.x
2.x.x	2.x.x - 4.x.x	3.x.x or 4.x.x

Troubleshooting

So if you are in trouble, here's where you can look for help.

The best place to ask questions is on StackOverflow (under the ngx-bootstrap tag) You can also join our Slack channel and link your stackoverflow question there. But try to avoid asking generic help questions directly on Slack since they can easily get lost in the chat. You can also search among the existing GitHub issues.

If, and only if, none of the above helped, please open a new issue.

Contribution

All contributions very welcome! And remember, contribution is not only PRs and code, but any help with docs or helping other developers to solve issues are very appreciated! Thanks in advance!
