express-prismic

Prismic.io support for ExpressJS

This is a set of helpers to use Prismic.io in an Express application. If you're starting from scratch, our NodeJS SDK is a good base.

Configuration

After including express-prismic in your package.json, simply import the prismic object:

var prismic = require('express-prismic').Prismic;

The Prismic object is extended from the Javascript Kit, so any attribute of the official kit, for example Predicates, is also available in the object exposed by express-prismic.

It needs to be initialized with your configuration:

prismic.init({
  apiEndPoint: "https://your-repo-name.prismic.io", // Mandatory
  linkResolver: function(doc) { // Mandatory
    return false;
  },
  accessToken: "xxx" // Optional
});

Usage

You can then create a Prismic context in your routes if you need to query your repository:

app.route('/').get(function(req, res) {
  var p = prismic.withContext(req,res); // This will retrieve the API object asynchronously (using a promise)
  p.getByUID('page', 'get-started', function (err, document) {
    res.render('index-prismic', {
      document: document
    });
  });
});

Several helper functions are available to query your repository. The most flexible is the query function:

  var p = prismic.withContext(req,res); // This will retrieve the API object asynchronously (using a promise)
  p.query(prismic.Predicate.fulltext('document', term), {
    page: 2,
    pageSize: 10
  }, function (err, results) {
    [...]
  });

Previews

You can preview any document including drafts in your production site, securely. All you have to do is:

• Include this route: app.route('/preview').get(prismic.preview);
• Configure the URL to that preview route in the settings of your repository
• Make sure that the Prismic Toolbar is included in your views
