Installation and usage

Install package with npm i bootstrap-email -S

To compile a default template:

const BootstrapEmail = require('bootstrap-email');

const template = new BootstrapEmail('<absolute-path-to-template>.html');

// const template = new BootstrapEmail([
//     '<absolute-path-to-first-template>.html',
//     '<absolute-path-to-second-template>.html',
// ]);
//
// const template = new BootstrapEmail('<div class="container">...</div>'); 

template.compileAndSave('<absolute-path-to-output>.html');

Alternatively use the Gulp plugin to integrate Bootstrap Email into your templating workflow.

Options

• style string (optional) - Path to css or scss file, which should be inlined. Default is bootstrap-email.scss
• head string (optional) - Path to css or scss file, which should be injected to head. Default is head.scss
• templates array<string> - Array with paths to html files you want to compile.
• logLevel

Methods

new BootstrapEmail(templates, options)

compile(): string | [{path: string, document: string}]

Performs a full compile and returns compiled document(s).

If only one template is about to compile, returns the compiled template, otherwise an array containing objects with the path of the input-file and the compiled document.

const singleTemplate = new BootstrapEmail('<absolute-path-to-template>.html');

// returns string
singleTemplate.compile();


const multipleTemplates = new BootstrapEmail(['<absolute-path>', ...]);

// returns [{path:'<absolute-path-to-source>', document: '...'}, ...]
multipleTemplates.compile();

compileAndSave(path): void

Performs a full compile and saves compiled files into given path.

If only one template is given, pass a full path including filename and extension. Otherwise pass only a directory name. The filenames will be used from the source files.

const singleTemplate = new BootstrapEmail('<absolute-path-to-template>.html');
singleTemplate.compileAndSave('<absolute-out-compiled>.html');


const multipleTemplates = new BootstrapEmail(['<absolute-path>', ...]);
multipleTemplates.compileAndSave('<absolute-out>');
