Function for JavaScript

function logo

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

!TIP(https://fxn.ai/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:

# Run this in Terminal
$ 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, 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]);
