This repository will illustrate how you can receive messages from and communicate with Metamaze.

Install dependencies

Install all dependencies by executing: yarn install

Communicating with Metamaze

Have a look at the API implementations if you want to see the implementation of the following functions.

Uploading files to Metamaze

Upload in a script

You can use the function uploadFilesInFolder to upload files to Metamaze in a script. It requires the following parameters:

Parameter	Type	Description
folderPath	string	Path to folder where the files are located
projectId	string	Id of project
organisationId	string	Id of organisation
token	string	Input API token of your project
pipelineType	"TRAINING" or "PRODUCTION"	Whether you want to upload to the training or production pipeline

Upload once

To upload all files in a folder one time, create a simple script upload.ts with contents

import { uploadFilesInFolder } from 'api/index';
 
uploadFilesInFolder("<folderPath>", 
    "<projectId>",
    "<organisationId>", 
    "<token>",
    "PRODUCTION")

and run ts-node upload.ts.

Retrieve upload from Metamaze

You can use the function getUploadById to retrieve an upload from Metamaze. It requires the following parameters:

Parameter	Type	Description
uploadId	string	Id of the upload you want to fetch
projectId	string	Id of project
organisationId	string	Id of organisation
token	string	Input API token of your project

Where can I find all these parameters?

• projectId and organisationId: Browse in Metamaze to your project and look at the url. It will look like this: https://app.metamaze.eu/5ccad715074ce2b850f6dddd/projects/5d6f52abbc1d177120addddd/production/uploads. In this example the organisationId = 5ccad715074ce2b850f6dddd and projectId = 5d6f52abbc1d177120addddd. The structure of the url is as follows: https://app.metamaze.eu/<organisationId>/projects/<projectId>/production/uploads.
• uploadId: Similar to projectId and organisationId. Again look at the url: https://app.metamaze.eu/5ccad715074ce2b850f6dddd/projects/5d6f52abbc1d177120addddd/production/uploads?uploadId=62d013cb5bd54e4b309f4ddd. In this example the uploadId = 62d013cb5bd54e4b309f4ddd.
• token: You can create/find a token in the project settings > Input > REST API. Select API as authentication protocol and generate a bearer token. This bearer token you need to use in the authentication headers.

Receiving messages from Metamaze

Once all dependencies are installed correctly, you can start the server by executing: yarn server

This will spin up an Express server that listens to http://localhost:4000/metamaze-output.

If you have deployed this Express server on your server and you have configured the project settings correctly, you should receive output messages from Metamaze in this function. See Express server.
