lodash.template

Template Compilation

Compiles templates into functions that can be used to interpolate values. The 'template' function takes a string and returns a compiled template function.

const _ = require('lodash.template');
const compiled = _.template('hello <%= user %>!');
console.log(compiled({ 'user': 'fred' }));
// => 'hello fred!'

HTML Escaping

Supports HTML escaping. The '<%-' sequence in the template string is used to escape values that are interpolated, preventing XSS attacks.

const _ = require('lodash.template');
const compiled = _.template('<b><%- value %></b>');
console.log(compiled({ 'value': '<script>' }));
// => '<b>&lt;script&gt;</b>'

Use of JavaScript Expressions

Allows the use of JavaScript expressions inside templates. This enables iteration and conditional logic within the template string.

const _ = require('lodash.template');
const compiled = _.template('<% _.forEach(users, function(user) { %><li><%- user %></li><% }); %>');
console.log(compiled({ 'users': ['fred', 'barney'] }));
// => '<li>fred</li><li>barney</li>'

Custom Delimiters

Supports custom delimiters. Users can define their own delimiters for interpolation, evaluation, and escaping.

const _ = require('lodash.template');
const compiled = _.template('hello ${ user }!', { 'interpolate': /\${([\s\S]+?)}/g });
console.log(compiled({ 'user': 'pebbles' }));
// => 'hello pebbles!'
