Are you eager to dive into coding? Follow these steps to kickstart a new project with Storyblok and a JavaScript frontend framework, and get started in just a few minutes!

Installation

npm install storyblok-js-client # yarn add storyblok-js-client

Compatibility

Version to install Support
Latest storyblok-js-client Modern browsers + Node 18+
Latest storyblok-js-client
+ Fetch polyfill like isomorphic-fetch		 Browsers and Node versions with no Fetch API support
Version 4 storyblok-js-client@4 Internet Explorer support

How to use it

Using the Content Delivery API

// 1. Import the Storyblok client
import StoryblokClient from "storyblok-js-client";

// 2. Initialize the client with the preview token
// from your space dashboard at https://app.storyblok.com
const Storyblok = new StoryblokClient({
  accessToken: <YOUR_SPACE_ACCESS_TOKEN>,
});

Using the Management API

// 1. Import the Storyblok client
import StoryblokClient from "storyblok-js-client";
const spaceId = <YOUR_SPACE_ID>;

// 2. Initialize the client with the oauth token
// from the my account area at https://app.storyblok.com
const Storyblok = new StoryblokClient({
  oauthToken: <YOUR_OAUTH_TOKEN>,
});

Storyblok.post(`spaces/${spaceId}/stories`, {
  story: { name: "xy", slug: "xy" },
});
Storyblok.put(`spaces/${spaceId}/stories/1`, {
  story: { name: "xy", slug: "xy" },
});
Storyblok.delete(`spaces/${spaceId}/stories/1`, null);

Using the RichTextResolver separately

You can import and use the RichTextResolver directly:

import RichTextResolver from 'storyblok-js-client/richTextResolver'

const resolver = new RichTextResolver()

const html = resolver.render(data)

NEW BRANCHES AND VERSIONS

The old master branch containing version 4.x.y has been moved to the v4 branch. We’ve renamed the master branch to main and now it contains version >= 5.0.0. If you wish to continue using the non Typescript version with axios, please use version 4. You can install it by running npm install https://github.com/storyblok/storyblok-js-client.git#4.x.x.

BREAKING CHANGES - FROM VERSION 6

Error handling from fetch has changed. Exceptions will be thrown as an object with the following structure:

{
  message: string
  status: number
  response: ISbResponse
}

You don't need to parse the error from the client's side.

BREAKING CHANGES - FROM VERSION 5

Added TypeScript - Version 5

We added TypeScript to our codebase, improving our code quality and assuring the correct implementation from the client's side. This change will probably break your code, because your Storyblok client's current implementation is possibly sending the wrong types to the source. If you use an IDE to code, you'll be able to hover the problematic cause and see what is being expected from the type. Yet, you can keep using our version without TypeScript.

Axios removal - Version 5

We removed our dependency on axios in Version 5. If you want to continue using our SDK with axios, please use version 4. The proxy feature was also removed in this version.

Fetch (use polyfill if needed) - Version 5

Version 5 is using native fetch API, supported by modern browsers and Node >= 18. If you are using an environment with no fetch API support, you can use a polyfill like isomorphic-fetch at the very beginning of your app entry point:

import 'isomorphic-fetch'
require('isomorphic-fetch') // in CJS environments

Documentation

Assets structure compatibility

We added retro-compatibility when using resolve_assets: 1 parameter under V2. Now, if you are using our V2 client, you should receive the assets structure just the same as V1.

Class Storyblok

Parameters

Activating request cache

The Storyblok client comes with a caching mechanism. When initializing the Storyblok client you can define a cache provider for caching the requests in memory.

The default behavior of the cache is clear: 'manual', that is, if you need to clear the cache, you need to call Storyblok.flushCache() or activate the automatic clear with clear: 'auto', as in the example below.

let Storyblok = new StoryblokClient({
  accessToken: <YOUR_SPACE_ACCESS_TOKEN>,
  cache: {
    clear: "auto",
    type: "memory",
  },
});

Passing response interceptor

The Storyblok client lets you pass a function that serves as a response interceptor to it. Usage:

let Storyblok = new StoryblokClient({
  accessToken: <YOUR_SPACE_ACCESS_TOKEN>,
  cache: {
    clear: "auto",
    type: "memory",
  },
  responseInterceptor: (response) => {
    // one can handle status codes and more with the response
    if (response.status === 200) {
      // handle your status here
    }
    // ALWAYS return the response
    return response;
  },
});

Removing response interceptor

One can remove the reponseInterceptor at any time, by calling the function ejectInterceptor as shown below:

Storyblok.ejectInterceptor()

Error handling

Exceptions will be thrown as an object with the following structure:

{
  message: Error // an Error object with the error message
  status: number
  response: ISbResponse
}

where,

interface ISbResponse {
  data: any
  status: number
  statusText: string
  headers: any
  config: any
  request: any
}

One should catch the exception and handle it accordingly.

Resolve relations using the Storyblok Bridge

With this parameter, you can resolve relations with live updates in the Storyblok JavaScript Bridge input event. It is possible to resolve content entries that are two levels deep, such as resolve_relations=page.author,page.products. Resolved relations can be found in the root of the API response, in the property rels. You can learn more about resolve_relations in this tutorial

It is important to note that when using the storyblok-js-client and other framework-specific SDKs, you don’t need to look for the rels array after resolving relations. The resolved relations are injected into the properties and, hence, are directly accessible through the properties. For example, you can access the authors array directly with page.author once it is resolved.

window.storyblok.resolveRelations(
  storyObject,
  relationsToResolve,
  callbackWhenResolved
)

Example

window.storyblok.on('input', (event) => {
  window.storyblok.addComments(event.story.content, event.story.id)
  window.storyblok.resolveRelations(
    event.story,
    ['post.author', 'post.categories'],
    () => {}
  )
})

Custom Fetch parameter

You can now pass an aditional paramater to the following calls: get, getAll, post, put, delete, getStory and getStories. This parameter is optional and it is the same as the Fetch API RequestInit parameter. It's important to note that we extended the RequestInit interface omitting the method parameter. This is because the method is already defined by the Storyblok client.

Example

const data = {
  story: {
    name: 'xy',
    slug: 'xy',
  },
}

Storyblok.get(
  'cdn/stories/home',
  {
    version: 'draft',
  },
  {
    mode: 'cors',
    cache: 'no-cache',
    body: JSON.stringify(data),
  }
)
  .then((response) => {
    console.log(response)
  })
  .catch((error) => {
    console.error(error)
  })

Method Storyblok#get

With this method you can get single or multiple items. The multiple items are paginated and you will receive 25 items per page by default. If you want to get all items at once use the getAll method.

Parameters

Example

Storyblok.get('cdn/stories/home', {
  version: 'draft',
})
  .then((response) => {
    console.log(response)
  })
  .catch((error) => {
    console.log(error)
  })

Method Storyblok#getAll

With this method you can get all items at once.

Parameters

Example

Storyblok.getAll('cdn/stories', {
  version: 'draft',
})
  .then((stories) => {
    console.log(stories) // an array
  })
  .catch((error) => {
    console.log(error)
  })

Method Storyblok#post (only management api)

Parameters

Example

Storyblok.post('spaces/<YOUR_SPACE_ID>/stories', {
  story: { name: 'xy', slug: 'xy' },
})
  .then((response) => {
    console.log(response)
  })
  .catch((error) => {
    console.log(error)
  })

Method Storyblok#put (only management api)

Parameters

Example

Storyblok.put('spaces/<YOUR_SPACE_ID>/stories/1', {
  story: { name: 'xy', slug: 'xy' },
})
  .then((response) => {
    console.log(response)
  })
  .catch((error) => {
    console.log(error)
  })

Method Storyblok#delete (only management api)

Parameters

Example

Storyblok.delete('spaces/<YOUR_SPACE_ID>/stories/1', null)
  .then((response) => {
    console.log(response)
  })
  .catch((error) => {
    console.log(error)
  })

Method Storyblok#flushCache

Parameters

Example

Storyblok.flushCache()

Method Storyblok#setComponentResolver

Parameters

Option 1: Use a switch case definition to render different components:

Storyblok.setComponentResolver((component, blok) => {
  switch (component) {
    case 'my-custom-component':
      return `<div class="my-component-class">${blok.text}</div>`
      break
    case 'my-header':
      return `<h1 class="my-class">${blok.title}</h1>`
      break
    default:
      return 'Resolver not defined'
  }
  switch (component) {
    case 'my-custom-component':
      return `<div class="my-component-class">${blok.text}</div>`
      break
    case 'my-header':
      return `<h1 class="my-class">${blok.title}</h1>`
      break
    default:
      return 'Resolver not defined'
  }
})

Option 2: Dynamically render a component (Example in Vue.js, which will only work with runtime template rendering enabled):

Storyblok.setComponentResolver((component, blok) => {
  return `<component :blok='${JSON.stringify(blok)}' is="${component}"></component>`
})

Method Storyblok#richTextResolver.render

Parameters

Example

Storyblok.richTextResolver.render(blok.richtext)

Optimizing images

You can instruct the richtext resolver to optimize images using Storyblok Image Service passing the option optimizeImages: true.

Example

Storyblok.richTextResolver.render(blok.richtext, { optimizeImages: true })

Also, it is possible to customize this option passing an object. All properties are optional and will be applied to each image in the field.

Example

const options = {
  optimizeImages: {
    class: 'w-full my-8 border-b border-black',
    width: 640, // image width
    height: 360, // image height
    loading: 'lazy', // 'lazy' | 'eager'
    filters: {
      blur: 0, // 0 to 100
      brightness: 0, // -100 to 100
      fill: 'transparent', // Or any hexadecimal value like FFCC99
      format: 'webp', // 'webp' | 'jpeg' | 'png'
      grayscale: false,
      quality: 95, // 0 to 100
      rotate: 0, // 0 | 90 | 180 | 270
    },
    // srcset accepts an array with image widths.
    // Example: [720, 1024, 1533]
    // will render srcset="//../m/720x0 720w", "//../m/1024x0 1024w", "//../m/1533x0 1280w"
    // Also accept an array to pass width and height.
    // Example: [[720,500], 1024, [1500, 1000]]
    // will render srcset="//../m/720x500 720w", "//../m/1024x0 1024w", "//../m/1500x1000 1280w"
    srcset: [720, 1024, 1533],
    sizes: ['(max-width: 767px) 100vw', '(max-width: 1024px) 768px', '1500px'],
  },
  optimizeImages: {
    class: 'w-full my-8 border-b border-black',
    width: 640, // image width
    height: 360, // image height
    loading: 'lazy', // 'lazy' | 'eager'
    filters: {
      blur: 0, // 0 to 100
      brightness: 0, // -100 to 100
      fill: 'transparent', // Or any hexadecimal value like FFCC99
      format: 'webp', // 'webp' | 'jpeg' | 'png'
      grayscale: false,
      quality: 95, // 0 to 100
      rotate: 0, // 0 | 90 | 180 | 270
    },
    // srcset accepts an array with image widths.
    // Example: [720, 1024, 1533]
    // will render srcset="//../m/720x0 720w", "//../m/1024x0 1024w", "//../m/1533x0 1280w"
    // Also accept an array to pass width and height.
    // Example: [[720,500], 1024, [1500, 1000]]
    // will render srcset="//../m/720x500 720w", "//../m/1024x0 1024w", "//../m/1500x1000 1280w"
    srcset: [720, 1024, 1533],
    sizes: ['(max-width: 767px) 100vw', '(max-width: 1024px) 768px', '1500px'],
  },
}

Storyblok.richTextResolver.render(blok.richtext, options)

Code examples

Define a custom cache for fine-grained control caching

Sometimes you want a custom cache implemention, for instance, when you want to host it on Redit for a distributed cache.

In such cases, you can use the custom cache and redefine the methods:

new StoryblokClient({
  accessToken: <YOUR_SPACE_ACCESS_TOKEN>,
  cache: {
    clear: "manual",
    type: "custom",
    custom: {
      get () {
        // example: get here cache from Redis
        return Promise.resolve(0);
      },
      getAll () {
        return Promise.resolve(0);
      },
      set () {
        return Promise.resolve(0);
      },
      flush () {
        return Promise.resolve(0);
      },
    }
  }
}

Filter by content type values and path

import StoryblokClient from 'storyblok-js-client'

let client = new StoryblokClient({
  accessToken: '<YOUR_SPACE_ACCESS_TOKEN>',
})

// Filter by boolean value in content type
client
  .get('cdn/stories', {
    version: 'draft',
    filter_query: {
      is_featured: {
        in: true,
      },
    },
  })
  .then((res) => {
    console.log(res.data.stories)
  })

// Get all news and author contents
client
  .get('cdn/stories', {
    version: 'draft',
    filter_query: {
      component: {
        in: 'news,author',
      },
    },
  })
  .then((res) => {
    console.log(res.data.stories)
  })

// Get all content from the news folder
client
  .get('cdn/stories', {
    version: 'draft',
    starts_with: 'news/',
  })
  .then((res) => {
    console.log(res.data.stories)
  })

Download all content from Storyblok

Following a code example using the storyblok-js-client to back up all content on your local filesystem inside a 'backup' folder.

import StoryblokClient from 'storyblok-js-client'
import fs from 'fs'

let client = new StoryblokClient({
  accessToken: '<YOUR_SPACE_ACCESS_TOKEN>',
})

let lastPage = 1
let getStories = (page) => {
  client
    .get('cdn/stories', {
      version: 'draft',
      per_page: 25,
      page: page,
    })
    .then((res) => {
      let stories = res.data.stories
      stories.forEach((story) => {
        fs.writeFile(
          './backup/' + story.id + '.json',
          JSON.stringify(story),
          (err) => {
            if (err) throw err

            console.log(story.full_slug + ' backed up')
          }
        )
      })

      let total = res.total
      lastPage = Math.ceil(res.total / res.perPage)

      if (page <= lastPage) {
        page++
        getStories(page)
      }
    })
}

getStories(1)

How to define a custom schema for the RichTextRenderer

To define how to add some classes to specific html attributes rendered by the rich text renderer, you need your own schema definition. With this new schema, you can pass it as the richTextSchema option when instantiate the StoryblokClient class. You must follow the default schema to do this.

Below, you can check an example:

import StoryblokClient from 'storyblok-js-client'

// the default schema copied and updated
import MySchema from './my-schema'

let client = new StoryblokClient({
  accessToken: '<YOUR_SPACE_ACCESS_TOKEN>',
  richTextSchema: MySchema,
})

client.richTextResolver.render(data)

If you just want to change the way a specific tag is rendered you can import the default schema and extend it. Following an example that will render headlines with classes:

Instead of <p>Normal headline</p><h3><span class="margin-bottom-fdsafdsada">Styled headline</span></h3> it will render <p>Normal headline</p><h3 class="margin-bottom-fdsafdsada">Styled headline</h3>.

import RichTextResolver from 'storyblok-js-client/richTextResolver'
import MySchema from 'storyblok-js-client/schema'

MySchema.nodes.heading = function (node) {
  let attrs = {}

  if (
    node.content &&
    node.content.length === 1 &&
    node.content[0].marks &&
    node.content[0].marks.length === 1 &&
    node.content[0].marks[0].type === 'styled'
  ) {
    attrs = node.content[0].marks[0].attrs
    delete node.content[0].marks
  }

  return {
    tag: [
      {
        tag: `h${node.attrs.level}`,
        attrs: attrs,
      },
    ],
  }
}

let rteResolver = new RichTextResolver(MySchema)
let rendered = rteResolver.render({
  content: [
    {
      content: [
        {
          text: 'Normal headline',
          type: 'text',
        },
      ],
      type: 'paragraph',
    },
    {
      attrs: {
        level: 3,
      },
      content: [
        {
          marks: [
            {
              attrs: {
                class: 'margin-bottom-fdsafdsada',
              },
              type: 'styled',
            },
          ],
          text: 'Styled headline',
          type: 'text',
        },
      ],
      type: 'heading',
    },
  ],
  type: 'doc',
})

console.log(rendered)

Handling access token overwrite

You can overwrite an access token, and prevent errors from the function call by adding a .catch() method for each access token as shown below.

const public = 'token1'
const preview = 'token2'

You can pass the tokens as follows:

client.getStories({token: 'preview'...}).then(previewResponse => ... ).catch()
client.getStories({token: 'public'...}).then(publicResponse => ... ).catch()
