typesense-js

Javascript client library for accessing the Typesense HTTP API.

This library can be used both on the server-side and on the client-side. The library's source is in ES6 and during build time, we transpile it to ES5 and generate two artifacts - one that can be used on the server-side and another that uses Browserify and can be used on the client side.

Installation

Option 1: Install via npm

npm install --save typesense

Install peer dependencies:

npm install --save @babel/runtime

Note: @babel/runtime is very a common dependency among many JS libraries. So instead of each library adding it as a dependency independently (which will cause multiple instances of @babel/runtime to be installed increasing bundle size), Babel's recommendation is that the libraries ask users to install it once as a direct dependency, so there's only one copy of @babel/runtime for the entire project. In some cases, your JS framework might already include @babel/runtime as a dependency.

Option 2: Include the minified JS file for use in the browser directly

<script src="dist/typesense.min.js"></script>

or via jsDelivr

<script src="https://cdn.jsdelivr.net/npm/typesense@2/dist/typesense.min.js"></script>

Usage

Read the documentation here for detailed examples: https://typesense.org/docs/api/

Tests are also a good place to know how the library works internally: test

Note: When using this library in a browser, please be sure to use an API Key that only allows search operations instead of the master API key. See doc/examples/server/keys.js for an example of how to generate a search only API key.

See Configuration.ts for a list of all client configuration options.

Request Timeouts and Abort Signals

The client supports both global timeout configuration and per-request abort signals:

Global Timeout Configuration

const client = new Typesense.Client({
  nodes: [{ host: "localhost", port: "8108", protocol: "http" }],
  apiKey: "xyz",
  connectionTimeoutSeconds: 30, // 30 second timeout for all requests
});

Per-Request Abort Signals

// Search with 5-second timeout
const controller = new AbortController();
setTimeout(() => controller.abort(), 5000);

const results = await client.collections("books").documents().search(
  {
    q: "*",
    query_by: "title",
  },
  { abortSignal: controller.signal },
);

// Collections with 2-second timeout
const collectionsController = new AbortController();
setTimeout(() => collectionsController.abort(), 2000);

const collections = await client.collections().retrieve({
  abortSignal: collectionsController.signal,
});

Note: The import() operation doesn't support abort signals or timeout configuration as it's designed to run to completion.

Examples

Here are some examples with inline comments that walk you through how to use the client: doc/examples

To run the examples, from the repo root:

npm run typesenseServer
node doc/examples/server/bulkImport.js

GatsbyJS Integration

If you use GatsbyJS for a framework, we have a plugin (that uses typesense-js behind the scenes) to automatically push your site data to Typesense when you build your site. Learn more here.

Firebase Integration

If you use Firebase, we have a Firebase extension (that uses typesense-js behind the scenes) to automatically push your Firestore data to Typesense. Learn more here.

Building UI components

Checkout the Typesense-InstantSearch.js (which uses typesense-js) for UI components you can use to quickly build powerful instant search experiences.

Compatibility

This table refers to server=>client compatibility. Newer versions of the client library maintain backwards compatibility with older versions of the server library.

Development

After checking out the repo, run npm install to install dependencies. Then run npm run test:local to run the linter and tests.

To release a new version, we use the np package:

$ npm install --global np
$ np

# Follow instructions that np shows you
