Searching and Filtering

Many plugins need the ability to make their content searchable and filterable. Flipper provides a component for this use-case called Searchable. This is a higher-order-component that can be used to wrap any table, list, or generic React component and adds Flipper's search bar on top of it.

We differentiate between search and filter, but both functionalities are provided by the Searchable component. Search is a custom string entered by the user. Filters cannot be added by the user directly, but are added programmatically from within your plugin.

Filters

Every filter has a key and a value. The key represents an attribute of the items you are filtering, and the value is the value that is compared with the items to see if the attribute matches. As an example, if you were filtering rows of a table, a filter key would be the id of a column.

There are two different types of filters:

  • include/exclude filters: An arbitrary string that must (or must not) be included in the filterable item.
  • enum: Allows the user to select one or more from a set of values, using a dropdown.

Higher Order Component

The Searchable() function adds three props to a React component:

addFilter: (filter: Filter) => void

Function allowing the component to add filters.

searchTerm: string

The search term entered into the search bar by the user.

filters: Array<Filter>

The list of filters that are currently applied.

Example

import type {SearchableProps} from 'flipper';
import {Searchable} from 'flipper';
class MyPluginTable extends Component<{
...SearchableProps
}> {
getRows() {
const {rows, searchTerm, filters} = this.props;
return rows.filter(row => {
// filter rows for searchTerm and applied filters
});
}
addFilter () {
this.props.addFilter({
type: 'include',
key: '...',
value: '...',
});
}
render() {
return <div>
<Button onClick={this.addFilter}>Filter</Button>
<Table rows={this.getRows()} />
</div>
}
}
export default SearchableTable = Searchable(MyPluginTable);
