jinabox.js is a lightweight, customizable set of components for querying and displaying results from Jina flows. You can use it for searching text, images, videos, audio or any kind of data with a Jina backend.


  • <jina-searchbar></jina-searchbar>

    • perform queries and view results in a single component
  • <jina-results></jina-results>

    • place results from searchbar in a separate area
  • <jina-floater></jina-floater>

    • standalone floating icon to enable searches from anywhere in the application
  • <jina-floater-chat></jina-floater-chat>

    • jina floater in the style of a chat application
  • Easy-to-use web components for Jina search backend

  • Users can drag and drop multi-modal data as search queries

  • Webcam and microphone support (in progress, contributions welcome! ❤️)

  • Visualize search results in a dropdown list or separate container

  • Highly customizable

jinabox.js in Action

Spin up a Jina Docker Image

jinabox.js is a frontend for querying Jina flows. You will need to spin up a Jina backend to get search results. Based on what you want to search, run one of our example Jina backends:

  • Pokedex (real image data): docker run -p 65481:65481 -e "JINA_PORT=65481" jinaai/ search
  • Southpark (real text data): docker run -p 45678:45678 jinaai/
  • MP4 mock (placeholder video data): docker run -p 65481:65481 -e "JINA_PORT=65481" jinaai/ search
  • Wav mock (placeholder audio data): docker run -p 65481:65481 -e "JINA_PORT=65481" jinaai/ search

Open jinabox.js in your Browser

Just go to in your browser to open up the search interface.

Set Server Endpoint

Based on the Docker port you are exposing (i.e. 65481 or 45678 in above Docker images), set jinabox's server endpoint to:


Important: If you are using a remote endpoint (non-localhost), make sure it is using HTTPS, not HTTP. Otherwise, JinaBox will not be able to make requests to your flow.

Start Searching!

Drag and drop images, video, or audio, or type in text to search.

Adding jinabox.js to Your Project

In your HTML source, include the minified script and initialize it with your endpoint:

<script src=""></script>
    jb = window.JinaBox
    jb.init('http://localhost:65481/api/search');  // http://localhost:65481/api/search is the endpoint of the REST gateway of a Jina flow with REST enabled.

Then add the jinabox web components into your application:




Now you can drag anything from anywhere (local/browser/webpage) to it and conduct the search.

Expected Response Structure

jinabox.js expects query responses to contain either of the following structures

  "search": {
    "docs": [
        "topkResults": [
            "matchDoc": {
              "docId": 14704,
              "weight": 1,
              "uri": "data:image/png;charset=utf,...",


  "search": {
    "docs": [
        "matches": [

            "weight": 1,
            "uri": "data:image/png;charset=utf,...",

Browser Support

jinabox.js runs on modern browsers including Chrome, Firefox, Safari (desktop and mobile) and Opera. Certain features (like recording audio/video) are not available on all browsers and jinabox will make these features available accordingly.


SSL Error on Localhost

Try http://localhost:65481/api/search, make sure to use http and localhost, instead of

Requests hanging or failing

Query your api with curl to ensure it is properly receiving, processing, and responding to requests. Ensure responses meet jinabox expected response structure.
