    Storybook GraphQL Kit npm version Storybook

    Storybook GraphQL

    Write GraphQL queries and pass response data to your components or just display them

    Why you want to use it

    1. Develop components

    Develop your components in isolation with actual backend stored data. With this addon you can add query to your stories and use fetched data as props for your components. You are flexible to use it with a single component or return an array of components - everything you need is just to write stories.

    2. Browse database

    You can simply use Storybook and this addon for rapid development of tools to browse your GraphQL endpoint. Just write the queries for data you want to show and it will be outputted as a table. If you have arrays, nested objects or images inside your query it will be turned to friendly visible form. Good for documenting things withing your team.

    Usage

    Install addon

    yarn add --dev @focus-reactive/storybook-graphql-kit

    Add addon to your Storybook

    // addons.js
    
    import "@focus-reactive/storybook-graphql-kit/register";

    Configure addon

    // config.js or in your stories.js
    import { addDecorator } from '@storybook/react';
    import { withGraphQL } from "@focus-reactive/storybook-graphql-kit";
    
    addDecorator(
      withGraphQL({
        endpoint: YOUR_GRAPHQL_ENDPOINT,
        token: YOUR_GRAPHQL_TOKEN,
      })
    );

    Write stories

    // stories.js
    
    import { QueryParams } from '@focus-reactive/storybook-graphql-kit';
    
    export default {
      title: 'Browse GraphQL',
    };
    
    // write a query in your preferred way
    const query = /* GraphQL */ `
      query($conferenceTitle: ConferenceTitle, $eventYear: EventYear, $name: String) {
        result: speakers(
          where: {
            conferenceEvents_some: { year: $eventYear, conferenceBrand: { title: $conferenceTitle } }
            name_contains: $name
          }
        ) {
          id
          bio
          name
          talks {
            title
          }
          avatar {
            mimeType
            url
          }
        }
      }
    `;
    
    // In Storybook v.5 you can simply export you stories from `stories.js` files. You can use `storiesOf(...).add(...)` syntax if prefer
    export const speakers = ({ graphQlResponse }) => {
      const data = graphQlResponse.result;
      return null;
      // or pass data to your components
    };
    
    // You need to pass parameters to your story
    speakers.story = {
      name: 'Conference Speakers',
      parameters: QueryParams({
        query,
        vars: { conferenceTitle: 'React_Day_Berlin', eventYear: 'Y2019' },
        searchVars: { name: '' },
        isConnected: true,
      }),
    };
    

    Note some details here:

    1. See how we return null from the story function. In this case the default UI will be used to display data in a table form. It's useful if you just want to quickly see the results of your request.
    2. If you return a React Component from your story it will behave as regular Storybook story except the additional field in the story context passed to the function that will contain fetched data. You story will be rendered only after data will be successfully received, so ({ graphQlResponse: { result } }) always has result of your query.
    3. You can pass variables in vars and searchVars fields to the query as you usually do for GraphQL requests. The difference of searchVars is that there will be input fields in the addon panel and users can use them for searching
    4. Settings passed to withGraphQL and to QueryParams are merged into one object before using. You can pass them in any order or even use only one of them. Just do it in the most convenient way for you

    Instead of passing options to the story how it's shown above you can import { Query } from '@focus-reactive/storybook-graphql-kit'; and pass all options via this helper:

    import { Query } from '@focus-reactive/storybook-graphql-kit';
    
    export const speakers = Query({
      name: 'Conference Speakers',
      query,
      vars: { conferenceTitle: 'React_Day_Berlin', eventYear: 'Y2019' },
      searchVars: { name: '' },
      viewId,
    });

    It does totally the same but in more compact way, especially if you only want to have the default view.

    Features

    1. You don't need to write stories or even use React if you only want to view the results of queries. It has convenient default UI to display your data.
    2. Expands nested objects to display in flat table
    3. Detects url fields with image sources and outputs them
    4. Input fields for GraphQL variables in the addon panel
    5. Handles GraphQL requests and renders story only with successfully received data
    6. Works fine with any GraphQL endpoint

    API

    You need to pass options to addon. You can pass them directly as story parameters, with withGraphQL decorator or with Query helper.

    import { Query } from '../../addon/decorator'
    
    export const pages = Query({ ...options });

    Common options for any GraphQL service:

    endpoint - Your GraphQL project endpoint

    token - GraphQL bearer token

    query - your GraphQL query

    vars - GraphQL variables

    searchVars - GraphQL variables you will set in the addon panel

    Stories options

    name - The name of the Story

    story - Story functions (if you don't use Storybook origin syntax)

    Writing stories

    When you writing stories with your own components you can access the raw query response alongside with parsed results:

    export const yourStory = ({ graphQlResponse }) => {
      // Result of your query. Usually what you want to use for components inside your App
      const data = graphQlResponse.result;
      // Array with information about fetched fields. The same that used for displaying default table
      const columns = graphQlResponse.columns;
      // Array of receiving objects. Works fine together with `columns` to output the parsed data
      const rows = graphQlResponse.rows;
    
      return data.map(props => <YouComponent {...props} />)
    };

    graphQlResponse.columns and graphQlResponse.rows are useful if you creating own tool to display your GraphQL data. Otherwise use graphQlResponse.result.

    Authoring Own Addons based on Storybook-GraphQL-Kit

    You can use API to extend this addon with your own representations of receiving data.

    import { withGraphQL } from '@focus-reactive/storybook-graphql-kit';
    
    const customRenderer = ({ key, value, ind, options }) => {
      if (key !== 'featured field') return null;
    
      return {
        id: key,
        getLabel: () => `${key}`,
        getValue: () => value,
        // return your custom React component or null for using `getValue`
        render: () => <CustomComponent/>,
      };
    };
    
    export const withYourServiceFeatures = withGraphQL
       .addRender(customRenderer)
       .addRender(customRenderer1)
       .addRender(customRenderer2);
