Bundled microcopy

The Sharetribe Web Template supports having a single language for the UI. Supported languages are English, French and Spanish, English being used by default. For information about changing the language, see the Changing the language article.

We use the React Intl library to represent UI microcopy and to format dates, numbers, and money values.

In addition to bundled microcopy, Flex allows modifying microcopy through the Flex Console:

• Microcopy in Flex
• How hosted microcopy works in the template

The microcopy file

All the bundled microcopy can be found in the src/translations/en.json file. The microcopy data is formatted as one JSON object with all the microcopy key-value pairs as properties.

The key - value syntax is as follows:

"<component name>.<microcopy key>": "<message>"

For example:

"ManageListingCard.viewListing": "View listing"

The keys are namespaced to the corresponding component. This is aligned with the component driven paradigm that the application follows. It might introduce duplication with same microcopy messages occurring multiple times in the microcopy file. On the other hand, it also emphasizes how all the components are independent, how a component can be used anywhere, and how modifications to a single component do not affect other components.

Using the marketplace microcopy

React Intl provides multiple ways to access the microcopy data but the most commonly used are the formatMessage function and the FormattedMessage tag provided by React Intl.

To use the formatMessage function, component needs to be wrapped with the injectIntl function which provides a render prop called intl. intl then provides all the React Intl translation functions, like formatMessage:

import { intlShape, injectIntl } from 'react-intl';

const SomeComponent = props => {
  const { intl } = props;

  const translation = intl.formatMessage({
    id: 'SomeComponent.someKey',
  });

  // ...
};

SomeComponent.propTypes = {
  // from injectIntl
  intl: intlShape.isRequired,
};

export default injectIntl(SomeComponent);

As for the FormattedMessage it just needs to be imported from react-intl and it takes the id prop:

<FormattedMessage id="SomeComponent.someKey" />

Other functions and componets can be explored in the React Intl documentation.

Formatting

React Intl uses the FormatJS formatters for shaping the microcopy messages based on given arguments. Here are a few examples on how to use FormatJS.

Arguments

Pass a named argument to the format function/component. For the following microcopy message:

"EnquiryForm.messageLabel": "Message to {authorDisplayName}",

Pass the author data in the FormattedMessage component:

<FormattedMessage
  id="EnquiryForm.messageLabel"
  values={{ authorDisplayName: 'Jane D' }}
/>

Or the the formatMessage function:

intl.formatMessage(
  { id: 'EnquiryForm.messageLabel' },
  { authorDisplayName: 'Jane D' }
);

Pluralization

With pluralization, a microcopy message can be formatted to adapt to a number argument.

"ManageListingsPage.youHaveListings":
  "You have {count} {count, plural, one {listing} other {listings}}",

This message takes the count argument and uses the plural, one and other keywords to format the last word of the microcopy message to be listing or listings based on the count. The pluralized message can be used with the FormattedMessage component:

<FormattedMessage
  id="ManageListingsPage.youHaveListings"
  values={{ count: 3 }}
/>

Or with the formatMessage function:

intl.formatMessage(
  { id: 'ManageListingsPage.youHaveListings' },
  { count: 1 }
);

Select an option

If you have two or more options that the microcopy message needs to show depending on another argument, you can use the select keyword to pass the necessary information to the message.

When you use select in the microcopy message, you will need to specify

• the variable determining which option to use (here: mode)
• the pattern we are following (here: select)
• the options matching each alternative you want to specify (here: class – there could be several options specified)
• an other option that gets used when none of the specified alternatives matches

 "BookingBreakdown.description": "{mode, select, day {You are booking the following days:} night {You are booking the following nights:} other {You are booking the following {unitType}:}}"

You can then use the microcopy message in the code with the formatMessage function:

// mode: the types of bookings or products available
// on the listing page, e.g. class, package, day, night
const mode = 'class';
const unitType = 'yoga class'
// For { mode: 'class', unitType: 'yoga class' },
// the message will read "You are booking the following yoga class.".
const description = intl.formatMessage(
  { id="BookingBreakdown.description" },
  { mode, unitType }
);

You can also use the message with the FormatMessage component

<FormattedMessage
  id="BookingBreakdown.description"
  values={{ mode: 'day' }}
/>

More formatting examples can be found from the FormatJS message syntax documentation.
