JinaAI JavaScript SDK

The JinaAI JavaScript SDK serves as an efficient conduit for incorporating Jina AI's suite of products — SceneXplain, PromptPerfect, Rationale, BestBanner, and JinaChat — into your JavaScript applications. It provides a potent interface to Jina AI's APIs, letting you craft and optimize prompts with ease, making it an indispensable tool for streamlined application development.

Installing

Package manager

Using npm:

$ npm install jinaai

Using Yarn:

$ yarn add jinaai

You can import the library using the import or require approach:

import JinaAI from 'jinaai';

const JinaAI = require('jinaai');

API secrets

To generate an API secret, you need to authenticate on each respective platform's API tab:

• SceneXplain API
• PromptPerfect API
• Rationale API
• JinaChat API
• BestBanner API

Note: Each secret is product-specific and cannot be interchanged. If you're planning to use multiple products, you'll need to generate a separate secret for each.

Example usage

Import the SDK and instantiate a new client with your authentication secret:

import JinaAI from 'jinaai';

const jinaai = new JinaAI({ secrets: {
    'promptperfect-secret': 'XXXXXX',
    'scenex-secret': 'XXXXXX',
    'rationale-secret': 'XXXXXX',
    'jinachat-secret': 'XXXXXX',
    'bestbanner-secret': 'XXXXXX',
}});

Describe images:

const descriptions = await jinaai.describe(
    'https://picsum.photos/200'
);

Evaluate situations:

const decisions = await jinaai.decide(
    'Going to Paris this summer', 
    { analysis: 'proscons' }
);

Optimize prompts:

const prompts = await jinaai.optimize(
    'Write an Hello World function in Typescript'
);

Generate complex answer:

const output = await jinaai.generate(
    'Give me a recipe for a pizza with pineapple'
);

Create images from text:

const output = await jinaai.imagine(
    'A controversial fusion of sweet pineapple and savory pizza.'
);

Use APIs together:

const situations = [
    'factory-1.png',
    'factory-2.png',
    'factory-3.png',
    'factory-4.png',
].map(i => toBase64(i));

const descriptions = await jinaai.describe(situations);

const prompt1 = [
    'Do any of those situations present a danger?',
    'Reply with [YES] or [NO] and explain why',
    ...descriptions.results.map(desc => 'SITUATION: ' + desc.output),
];

const analysis = await jinaai.generate(
    prompt1.join('\n')
);

const prompt2 = [
    'What should be done first to make those situations safer?',
    'I only want the most urgent situation',
    ...descriptions.results.map(desc => 'SITUATION: ' + desc.output),
];

const recommendation = await jinaai.generate(propmt2.join('\n'));

const swot = await jinaai.decide(
    recommendation.output,
    { analysis: 'swot' }
);

const banners = await jinaai.imagine(
    descriptions!.results.map(d => d.output)
);

Raw Output

You can retrieve the raw output of each APIs by passing raw: true in the options:

const descriptions = await jinaai.describe(
    'https://picsum.photos/200',
    { raw: true }
);

console.log(descriptions.raw)

Custom Base Urls

Custom base Urls can be passed directly in the client's constructor:

const jinaai = new JinaAI({
    baseUrls: {
        promptperfect: 'https://promptperfect-customurl.jina.ai',
        scenex: 'https://scenex-customurl.jina.ai',
        rationale: 'https://rationale-customurl.jina.ai',
        jinachat: 'https://jinachat-customurl.jina.ai',
        bestbanner: 'https://bestbanner-customurl.jina.ai',
    }
});
