Installation

Intall Modzy's JavaScript SDK with NPM

npm install @modzy/modzy-sdk

or YARN

yarn add @modzy/modzy-sdk

Usage/Examples

Initializing the SDK

Initialize your client by authenticating with an API key. You can download an API Key from your instance of Modzy.

import { ModzyClient } from "@modzy/modzy-sdk";

const modzyClient = new ModzyClient({
  apiKey: "Valid Modzy API Key", //e.g., "JbFkWZMx4Ea3epIrxSgA.a2fR36fZi3sdFPoztAXT"
  url: "Valid Modzy URL", //e.g., "https://trial.app.modzy.com"
});

Running Inferences

Raw Text Inputs

Submit an inference job to a text-based model by providing the model ID, version, and raw input text.

//Submit text to v1.0.1 of a Sentiment Analysis model, and to make the job explainable, change explain=True
const { jobIdentifier } = await modzyClient.submitJobText({
  modelId: "ed542963de",
  version: "1.0.1",
  sources: {
    firstPhoneCall: {
      "input.txt": "Mr Watson, come here. I want to see you.",
    },
  },
});

File Inputs

Pass a file from your local directory to a model by providing the model ID, version, and the filepath of your sample data:

// Submit a job to the Image-Based Geolocation model
const { jobIdentifier } = await modzyClient.submitJobFile({
  modelId: "aevbu1h3yw",
  version: "1.0.1",
  sources: {
    nyc-skyline: {
      image: "./images/nyc-skyline.jpg",
    },
  },
});

Embedded Inputs

Convert images and other large inputs to base64 embedded data and submit to a model by providing a model ID, version number, and dictionary with one or more base64 encoded inputs:

const fs = require('fs');

//Embed input as a string in base64
const imageBytes = fs.readFileSync('images/tower-bridge.jpg');
//Prepare the source dictionary
let sources = { "tower-bridge": { "image": imageBytes } };

//Submit the image to v1.0.1 of an Imaged-based Geolocation model
const { jobIdentifier } = await modzyClient.submitJobEmbedded("aevbu1h3yw", "1.0.1", "application/octet-stream", sources);

Inputs from Databases

Submit data from a SQL database to a model by providing a model ID, version, a SQL query, and database connection credentials:

//Add database connection and query information
const dbUrl = "jdbc:postgresql://db.bit.io:5432/bitdotio"
const dbUserName = DB_USER_NAME;
const dbPassword = DB_PASSWORD;
const dbDriver = "org.postgresql.Driver";
//Select as "input.txt" becase that is the required input name for this model
const dbQuery = "SELECT \"mailaddr\" as \"input.txt\" FROM \"user/demo_repo\".\"atl_parcel_attr\" LIMIT 10;";

//Submit the database query to v0.0.12 of a Named Entity Recognition model
const { jobIdentifier } = await modzyClient.submitJobJDBC("a92fc413b5", "0.0.12", dbUrl, dbUserName, dbPassword, dbDriver, dbQuery)}

Inputs from Cloud Storage

Submit data directly from your cloud storage bucket (Amazon S3 supported) by providing a model ID, version, and storage-blob-specific parameters.

AWS S3

//Define sources dictionary with bucket and key that points to the correct file in your s3 bucket
const bucketName = "s3-bucket-name";
const fileKey = "key-to-file.txt";
let sources = { "sampleText": { "input.txt": { 'bucket': bucketName, 'key': fileKey } } };

const accessKey = ACCESS_KEY_ID;
const secretAccessKey = SECRET_KEY;
const region = "us-east-1";

//Submit s3 input to v1.0.1 of a Sentiment Analysis model
const { jobIdentifier } = await modzyClient.submitJobAWSS3("ed542963de", "1.0.1", accessKey, secretAccessKey, region, sources)

Getting Results

Hold until the inference is complete:

await modzyClient.blockUntilJobComplete(jobIdentifier);

Get the output results:

const result = await modzyClient.getResult(jobIdentifier);

SDK Code Examples

  • samples provides details for specific use cases and are intended to be run using Node.js, but most can also run in the browser
  • react examples contains react components that can be used to the browser to send files to, or retrieve files from Modzy.

To run these examples, make sure to update API_KEY and MODZY_URL to valid values.

Running Tests

The Jest tests expect that there is a .env file at the root of the repo that contains a valid Modzy api key like this:

API_KEY=xxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxx
