In this example, we will see how we can work with Machine Learning applications written in Python with a NodeJS Script, to build a Polyglot Machine Learning application for scraping similar news articles.
Install MetaCall CLI:
$ curl -sL https://raw.githubusercontent.com/metacall/install/master/install.sh | shInstall application dependencies:
- For Python:
metacall pip3 install -r requirements.txt - For NodeJS:
metacall npm i readline-sync
$ metacall app.jsOnce the application is kick-started, you will be prompted to enter a News Article which you would like to find similar articles for. Let's use this sample article for testing our application: https://www.nytimes.com/2021/03/23/business/teslas-autopilot-safety-investigations.html
Here is the application output:
$ metacall app.js
Information: Global configuration loaded from /gnu/store/5cxmq6y8z24ijnvhh6lndgpriwnhf3jl-metacall-0.3.17/configurations/global.json
Enter the News URL:

Script (app.js) loaded correctly
After deploying the application into the FaaS https://dashboard.metacall.io, it can be accessed with (change <your_alias> by the alias you used to sign up):
curl -X POST https://api.metacall.io/<your_alias>/ml-news-article-scraper-example/v1/call/similarNews -X POST --data '{ "url": "https://www.nytimes.com/2021/03/23/business/teslas-autopilot-safety-investigations.html" }'
