` package. Here is an example of how you can use it:

javascript

const express = require(‘express’);

const app = express();

const nunjucks = require(‘nunjucks’);

app.set(‘view engine’, ‘njk’);

app.get(‘/’, (req, res) => {

res.render(‘index.njk’);

});

app.listen(3000, () => {

console.log(‘Server started on port 3000’);

});

In this example, we’re setting the view engine to `njk`, which is the extension for Nunjucks templates. Then, when we render the `index` template, Nunjucks will look for a file named `index.njk` in the `views` directory.

Here’s an example of what the `index.njk` template might look like:

njk

In this example, the template is a simple HTML file with a title and a heading. You can use Nunjucks to render dynamic content by using variables and filters. For example:

njk

In this example, the template is using two variables: `title` and `name`. You can pass these variables to the template when you render it:

javascript

app.get(‘/’, (req, res) => {

const title = ‘My App’;

const name = ‘John Doe’;

res.render(‘index.njk’, { title, name });

});

When you render the template, Nunjucks will replace the variables with the values you passed in. This allows you to create dynamic templates that can be used to render different types of content.

/jest.config.js

module.exports = {

// Enable jest to work with nunjucks

moduleFileExtensions: [‘js’, ‘nunjucks’],

// Tell jest to use nunjucks as a template engine

templateEngine: ‘nunjucks’,

// Set the nunjucks template engine options

nunjucksOptions: {

// Set the nunjucks template engine options

autoescape: false,

};

Now, you can use nunjucks templates in your tests. For example, you can create a `__tests__/example.test.nunjucks` file with the following content:

{% extends “base.html” %}

This is a test paragraph.

And then, in your test file, you can use the `render` function to render the template:

// __tests__/example.test.js

import { render } from ‘@testing-library/jest’;

import { nunjucks } from ‘nunjucks’;

describe(‘Example Test’, () => {

it(‘renders the test template’, () => {

const template = nunjucks.render(‘example’, {});

expect(template).toContain(‘Test Template’);

expect(template).toContain(‘This is a test paragraph.’);

});

This is just a basic example, but you can use nunjucks templates in your tests to render complex templates with data.

I hope this helps! Let me know if you have any questions. 😊
