Function for JavaScript

Run AI prediction functions (a.k.a "predictors") in the browser and Node.js. With Function, you can build AI-powered apps by creating and composing GPU-accelerated predictors that run in the cloud. In a few steps:

!CAUTION Never embed access keys client-side (i.e. in the browser). Instead, create a proxy URL in your backend.

Installing Function

Function is distributed on NPM. Open a terminal and run the following command:

npm install fxnjs

Retrieving your Access Key

Head over to fxn.ai to create an account by logging in. Once you do, generate an access key:

generate access key

Making a Prediction

First, create a Function client and specify your access key:

import { Function } from "fxnjs"

// Create a Function client
const fxn = new Function({ accessKey: "<ACCESS KEY>" });

Then make a prediction:

// Make a prediction
const prediction = await fxn.predictions.create({
    tag: "@samplefxn/greeting",
    inputs: {
        name: "Rhea"
    }
});
// Log the result
console.log(prediction.results[0]);
