Piral Search ·

This is a plugin that only has a peer dependency to piral-core. What piral-search brings to the table is a set of Pilet API extensions that can be used with piral or piral-core to bring enhanced search capabilities to pilets via your Piral instance.

By default, these API extensions are not integrated in piral, so you'd need to add them to your Piral instance.

Why and When

In many cases the frontend should provide an extensive search functionality. If this search can or should also work in context-sensitive ways (e.g., depending on which microfrontends are loaded different search options are used or available) then this plugin might be useful. It allows pilets to register search providers which can handle search queries.

Documentation

The following functions are brought to the Pilet API.

registerSearchProvider

Adds a search provider to be used in the app shell. The search provider will always be invoked when the global search is triggered.

If the first argument is a string a named search provider is registered. A named search provider can also be removed.

unregisterSearchProvider

Removes a search provider from the app shell. This requires a named search provider.

Usage

::: summary: For pilet authors

You can use the registerSearchProvider function from the Pilet API to add a new search provider in the app shell.

Note: When the first argument is a string we call it a named search provider.

Example use:

import { PiletApi } from '<name-of-piral-instance>';
import { MyTile } from './MyTile';

export function setup(piral: PiletApi) {
  piral.registerSearchProvider(MyTile);
}

You can use the unregisterSearchProvider function from the Pilet API to remove a previously added search provider from the app shell.

Note: You'll need to have added a named search provider in order to be able to remove it.

Example use:

import { PiletApi } from '<name-of-piral-instance>';
import { MyTile } from './MyTile';

export function setup(piral: PiletApi) {
  // register with a name
  piral.registerSearchProvider('first', MyTile);
  // and unregister; maybe some time later?
  piral.unregisterSearchProvider('first');
}

:::

::: summary: For Piral instance developers

The provided library only brings API extensions for pilets to a Piral instance.

For the setup of the library itself you'll need to import createSearchApi from the piral-search package.

import { createSearchApi } from 'piral-search';

The integration looks like:

const instance = createInstance({
  // important part
  plugins: [createSearchApi()],
  // ...
});

Via the options the initially displayed results can be defined. The current query can also be set.

For example:

const instance = createInstance({
  // important part
  plugins: [createSearchApi({
    query: '!help',
    results: [
      <div>
        Help was found!
      </div>,
    ],
  })],
  // ...
});
