This is the README for version 1.x.x of ditto-react. If you're on an earlier version, please click here.

Ditto React

ditto-react makes it easy to integrate a React app with Ditto.

• Exposes Ditto data to your application through an easy-to-wrap provider
• Offers support for localizing using Ditto variants
• Works hand-in-hand with the Ditto CLI

Ditto also works with many popular 3rd party i18n libraries. Check out our demo repository for an example of how Ditto can be integrated into development using react-i18next.

Installation

You can install ditto-react from npm:

# as a dev dependency
npm install --save-dev ditto-react

ditto-react comes with TypeScript bindings out of the box.

Getting Started

Set up the CLI

First, you'll need to set up the Ditto CLI in your repository; initialize the CLI in a place that is accessible to your React code.

For example, if you have a project created with create-react-app, initialize the CLI in the src folder, because directories outside of it can't be imported from your application. See the Ditto CLI's README for more information on how to set it up and start syncing data from your workspace.

Set up the provider

At the root of your application, import and wrap your app in DittoProvider; pass its source prop data imported from the ditto folder generated by the CLI's pull command:

import DittoProvider from "ditto-react";
import dittoData from "./ditto";

const App = () => <DittoProvider source={dittoData}>...</DittoProvider>;

Start implementing text components

Anywhere in your application that requires product copy, import and use the Ditto component:

import { Ditto } from 'ditto-react';

const HomePage = () => (
  <div>
    <h1><Ditto componentId="home.title" /></h1>
    <h2><Ditto componentId="home.subtitle"></h2>
    <p><Ditto componentId="home.body" /></p>
    <footer>
      <ul>
        <li>
          <a href="/home"><Ditto componentId="footer.links.home" /></a>
        </li>
        <li>
          <a href="/contact"><Ditto componentId="footer.links.contact" /></a>
        </li>
        <li>
          <a href="/about"><Ditto componentId="footer.links.about" /></a>
        </li>
      </ul>
    </footer>
  </div>
)

Localize with variants

If the components in your Ditto workspace have variants, you can use them in ditto-react by passing a variant prop to DittoProvider. The value of the prop should be equal to the API ID of the variant:

import DittoProvider from "ditto-react";
import dittoData from "./ditto";

const options = ["base", "spanish", "korean"];

const App = () => {
  const [variant, setVariant] = useState(options[0]);

  return (
    <DittoProvider source={dittoData} variant={variant}>
      ...
    </DittoProvider>
  );
};

Interpolation

Support dynamic text by specifying variables:

<Ditto textId={textId} />
// The cart contains {{itemName}}
<Ditto textId={textId} variables={{ itemName: "apples" }}/>
// The cart contains apples
<Ditto textId={textId} variables={{ itemName: "pears" }}/>
// The cart contains pears

Learn how to configure Ditto variables: https://www.dittowords.com/docs/variables

Plurals

Ditto pluralization can be utilized by passing in the count prop:

<Ditto textId={textId}/> // The cart contains {{numItems}} items
<Ditto textId={textId} variables={{ numItems: 3 }} count={3}/> // The cart contains 3 items
<Ditto textId={textId} variables={{ numItems: 1 }} count={1}/> // The cart contains 1 item
<Ditto textId={textId} variables={{ numItems: 0 }} count={0}/> // The cart contains no items

The count prop is indexed to the following plural keys: | Plural Form | count | | ---- | ---- | | zero | 0 | | one | 1 | | two | 2 | | few | 3, 4, 5 | | many | 6, 7, ..., 99 | | other | 100, 101, ... |

If the provided count value does not fall in the range associated with a defined plural, the 'other' plural form will be used as a default if it is defined. If 'other' is not defined, the base text value will be used as a final fallback.

To configure text plural forms in Ditto, please refer to: https://www.dittowords.com/docs/pluralization

To read more about pluralization and see other examples of how it is used in i18n at large, please refer to the pluralization page in the i18next docs: https://www.i18next.com/translation-function/plurals

Example

To see a working React app utilizing the Ditto CLI and ditto-react, please refer to the Ditto Demo project: https://github.com/dittowords/ditto-demo.

Reference

DittoProvider

The DittoProvider component should wrap all parts of your component tree that will display copy from Ditto.

If variant is supplied, base text values will be used as a fallback for any pieces of text where corresponding variant values can't be found.

Props

| Prop | Type | Description | | ----------- | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | source | JSON (required) | Copy data imported from the CLI-generated ditto folder — see Source for more info | | variant | String (optional) | The API ID of a variant; if specified, all descendant Ditto components will attempt to display the value of that variant (requires usage of the variants CLI option) | | projectId | String (optional) | The ID of a project in Ditto; can also be ommitted from the provdier and passed as a direct prop to Ditto components |

Example

import DittoProvider, { Ditto } from "ditto-react";
import source from "./ditto";

<DittoProvider source={source}>{/* the rest of your app */}</DittoProvider>;

Ditto

The Ditto component is used for rendering text. Text can be rendered from components in your component library (recommended) or from projects in your workspace.

Which method you use depends on how you've configured your CLI options. Please refer to the Ditto CLI and Ditto Demo projects for more information.

Component Library (recommended)

| Prop | Type | Description | | ------------- | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | componentId | string | The API ID of a component in your component library. If a variant prop is passed to an ancestor DittoProvider, will attempt to display the specified variant's value for the passed componentId; otherwise, will default to displaying base text. | | variables | object (optional) | This prop contains a map of all the variable key-value pairs you wish to pass into your text | | count | number (optional) | This value is used to specify which plural case you wish to use |

Example

<Ditto
  componentId="footer.links.contact-us"
  variables={{ email: "[email protected]" }}
  count={1}
/>

Project

| Prop | Type | Description | Example | | ----------- | ---------------------- | --------------------------------------------------------------------------------------------------------------- | ----------------------------------- | | projectId | string (semi-required) | ID of a project in Ditto; required if a projectId isn't found in an ancestor DittoProvider | | textId | string (optional) | ID of a single text item in Ditto | | | frameId | string (optional) | ID of a frame in Ditto | | | blockId | string (optional) | ID of a block in Ditto | | | filters | object (optional) | object of filters for text items returned. Currently supports a single parameter: tags, an array of tag strings | { tags: ["SELECTS"]} | | variables | object (optional) | This prop contains a map of all the variable key-value pairs you wish to pass into your text | { email: "[email protected]" } | | count | number (optional) | This value is used to specify which plural case you wish to use | 1 |

Examples

If you pass textId, the specified text string will be rendered:

<Ditto
  textId="text_6151fa25151df3024333a8cb"
  projectId="project_613a9b8fd268f614cae17469"
/>

If you pass frameId and/or blockId, the specified frame/block object will be passed to a child function:

<Ditto
  frameId="frame_6151fa25151df3024333a8bd"
  blockId="my_block"
  projectId="project_613a9b8fd268f614cae17469"
>
  {(block) =>
    Object.keys(block).map((id) => <div key={block[id]}>{block[id]}</div>)
  }
</Ditto>

Type-specific component exports

In addition to the <Ditto /> component, individual exports of each specific component type are also available. These behave identically to passing the respective prop configurations to the <Ditto /> component, but may provide a better experience for TypeScript users due to their improved out-of-the-box type safety and inference:

import {
  DittoFrame,
  DittoBlock,
  DittoText,
  DittoComponent, // rendering components from your Ditto component library
} from "ditto-react";

Hooks (experimental)

Hooks are also available for consuming data from a <DittoProvider />. The two hooks currently exposed have unpolished ergonomics due to the manner in which they evolved from legacy constraints.

In future versions of ditto-react, a hooks-based API will be the primary way through which data is accessed (instead of components), and the API will likely have some differences from what is currently available.

import { useDittoComponent, useDittoSingleText } from "ditto-react";

const componentText = useDittoComponent({ componentId: "xxx-xxx" });
const text = useDittoSingleText({ textId: "xxx-xxx" }); // assumes `projectId` was specified for an ancestor <DittoProvider />

Additional Examples

Example: Single Text

The Ditto component can be used to fetch a specific text item from the Ditto project using its API ID. Note that you can edit IDs for text, blocks, and frames directly the Ditto web app:

<Ditto textId="text_601cc35c5bsdfe42cc3f6f8ac59" />

Example: Fetch Block

You can also fetch an entire Block in Ditto at once by specifying the frameId and the blockId.

It will return as an entire JSON object of the frame. You can pull out specific IDs of text you'd like to pass to its children.

<Ditto frameId="frame_601cc35d5be42cc3f6f8ad15" blockId="hero">
  {({ hero_h1, text_601cc35c5be42cc3f6f8ac46, hero_cta }) => (
    <div>
      <h1>{hero_h1}</h1>
      <h2>{text_601cc35c5be42cc3f6f8ac46}</h2>
      <button>{hero_cta}</button>
    </div>
  )}
</Ditto>

You can also iterate through the entire block (just as you can with any other object) to display each one.

<Ditto frameId="header" blockId="navigation">
  {(block) => {
    return Object.keys(block).map((id) => (
      <div key={block[id]}>{block[id]}</div>
    ));
  }}
</Ditto>

Example: Fetch Frame

You can also fetch an entire Block in Ditto at once by just specifying the frameId. With it, you can fetch specific blocks, or iterate through all blocks and containing IDs as needed.

<Ditto frameId="frame_601cc35d5be42cc3f6f8ad17">
  {(frame) => {
    return Object.keys(frame.blocks).map((blockId) => (
      <div className={style.footerCol} key={blockId}>
        {Object.keys(frame.blocks[blockId]).map((textId) => (
          <div className={style.link} key={textId}>
            {frame.blocks[blockId][textId]}
          </div>
        ))}
      </div>
    ));
  }}
</Ditto>

Example: Filtering by Tags

If you want to filter the text fetched by properties contained in the project itself, you can specify parameters to the filter prop of the Ditto component. This currently only supports the Tags field in Ditto, but will be expanded in the future to filter on any other metadata properties.

// will only return text with the "TOP_NAV" tag
<Ditto
  frameId="frame_601cc35d5be42cc3f6f8ad15"
  blockId="navigation"
  filters={{ tags: ["TOP_NAV"] }}
>
  {(block) => {
    return Object.keys(block).map((id) => (
      <div className={style.link} key={block[id]}>
        {block[id]}
      </div>
    ));
  }}
</Ditto>

Source

The React provider takes structured JSON outputs from Ditto as the source. These can be linked and automatically updated via our API/CLI, or exported manually via the Ditto web app.

If you're using manual exports from the Ditto web app, turn on Developer Mode in the toolbar of project you're working from to generate API IDs. Then, export your file formatted with the IDs into your local directory .
