View integration

You can integrate PreviewLinks with any Node.js server side application. Here's an Express.js example serving a simple HTML template:

const express = require('express')
const { PreviewLinks } = require('@previewlinks/node-previewlinks')

const app = express()
const previewlinks = new PreviewLinks({ apiToken: '<YOUR_API_TOKEN>' })

app.get('/', (request, response) => {
    const image = previewlinks.signedImageUrl({
        templateId: 732,
        fields: {
            'previewlinks': 'Hello from Node.js',

    return response.send(`
        <!DOCTYPE html>
        <html lang="en">
                <meta charset="UTF-8" />

                <meta http-equiv="X-UA-Compatible" content="IE=edge" />

                <meta name="viewport" content="width=device-width, initial-scale=1.0" />

                <title>Your Application</title>

                <meta property="og:image" content="${image}" />

                <meta name="twitter:image" content="${image}" />

                <h1>Hello from Node.js</h1>
