MTA fair price tollbooth HighWei - npm package support for puppeteer to XPATH scrape?

Questions:

1. Can we use custom node.js libraries somehow?

I tried:

npm i puppeteer

but get error:

__Error thrown in sandboxed source code__
Cannot find module 'puppeteer'
__Simulated On-Chain Response__
Error message returned to client contract: "Cannot find module 'puppeteer'"

2. Can

Functions.makeHttpRequest

return an object which can be XPATH scraped in a simple way?

Hi @MarcusWentz, I'll try to answer your questions.

re: 1. Can we use custom node.js libraries somehow?

-At the moment, no, only vanilla Node.js features are supported. Check https://docs.chain.link/chainlink-functions/resources/service-limits for more info.

re: 2. Can Functions.makeHttpRequest return an object which can be XPATH scraped in a simple way?

-To my best knowledge, it is possible in theory, most likely as a responseType 'document' or 'text', but you will need to handle interpreting XPATH by yourself without using external NPM libraries since XPATH natively isn't a feature of Node.js
