Using Handlebars.js with Angular CLI versions 6 and above: A Step-by-Step Guide

Looking to create a customizable customer letter in either plain text or HTML format that can be edited further by the customer. Considering using Handlebars.js to render an HTML template with mustache tags, using a JSON object for business information.

This is what I have done so far:

import * as Handlebars from 'handlebars';

...
            const template = Handlebars.compile(this.exampleHtmlTemplate);
            this.note = template({ title: 'My title', body: 'My body' });

Encountered an error while compiling with Angular CLI:

chunk {vendor} vendor.js, vendor.js.map (vendor) 7.84 MB [initial] [rendered]

WARNING in ./node_modules/handlebars/lib/index.js 22:38-56
require.extensions is not supported by webpack. Use a loader instead.

WARNING in ./node_modules/handlebars/lib/index.js 23:2-20
require.extensions is not supported by webpack. Use a loader instead.

WARNING in ./node_modules/handlebars/lib/index.js 24:2-20
require.extensions is not supported by webpack. Use a loader instead.

ERROR in ./node_modules/handlebars/lib/index.js
Module not found: Error: Can't resolve 'fs' in 'C:\...\NGSource\node_modules\handlebars\lib'

Using Angular 7.2.6 and Angular CLI 7.3.3. How can Handlebars.js be integrated with Angular2+? Alternatively, are there low-level Angular APIs that can be used to render/compile a template with mustache tags and JSON data into standard HTML/text?

Answer №1

Why not experiment with an alternative import method:

import * as Mustache from 'mustache/dist/cjs/mustache';
