Function for JavaScript

Run Python functions (a.k.a "predictors") locally in the browser and Node.js, with full GPU acceleration and zero dependencies.

Tip

Join our waitlist to bring your custom Python functions and run them on-device across Android, iOS, macOS, Linux, web, and Windows.

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:

Making a Prediction

First, create a Function client, specifying 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: "@fxn/greeting",
    inputs: { name: "Rhea" }
});

// Log the result
console.log(prediction.results[0]);
