ButterCMS JS client

Documentation

For a comprehensive list of examples, check out the API documentation.

Installation

Requires node.js version 4 or greater.

npm install buttercms --save

Butter can also be included directly in HTML:

<script src="https://cdnjs.buttercms.com/buttercms-1.2.8.min.js"></script>

Overview

Every resource is accessed via your butter instance:

const butter = require('buttercms')('api_token_567abe');

Using ES6:

import Butter from 'buttercms';
const butter = Butter('api_token_567abe');

Using TypeScript:

import Butter from 'buttercms';
const butter = Butter('api_token_567abe');

Using CDN:

<script>
  const butter = Butter('api_token_567abe');
</script>

Every resource method returns a promise:

// Get blog posts
butter.post.list({page: 1, page_size: 10}).then(function(response) {
  console.log(response)
})

Pages

Where you see params it is a plain js object, e.g. {page: 1}. For a list of params see the API documentation

• page
  • retrieve(page_type, page_slug[, params])
  • list(page_type[, params])

// Get page
butter.page.retrieve('casestudy', 'acme-co').then(function(resp) {
 console.log(resp)
});

Collections

• content
  • retrieve(collection[, params])

// Get FAQ
butter.content.retrieve(["faq"], {locale: 'es'}).then(function(resp) {
  console.log(resp)
});

Preview mode

Preview mode can be used to setup a staging website for previewing content fields or for testing content during local development. To fetch content from preview mode add an additional argument, true, to the package initialization:

const butter = require('buttercms')('your butter API token', true);

Or use an environment variable:

const butter = require('buttercms')('your butter API token', process.env.BUTTER_PREVIEW_MODE);

Blog Engine

  • retrieve(slug[, params])

Timeouts

The default timeout threshold is 3000ms but you can change it:

const butter = require('buttercms')('your butter API token', false, 5000);

Axios hook

If you need to custom headers, caching, automatic retry or any other specific functionality on the transport layer, you can hook up into the Axios instance creation process. Supply the axiosHook callback parameter and Butter will call you when Axios is being created:

function axiosHook(axios) {
  axios.interceptors.request.use(function requestLogger(config) {
    console.warn("Axios requested", config.url, config.params)

    return config;
  })
}

const butter = require('buttercms')('your butter API token', false, 5000, axiosHook);
