I can't find any docs on how to use packages with functions so I'm assuming we can't? Does this limit how useful functions are since we can't just import, say, openai or stripe?

kian•9/19/23, 11:27 AM

Same as any other project -

npm i <package>

npm i <package>

npm i <package>

npm i <package> and

import { foo } from "package"

import { foo } from "package"

import { foo } from "package"

import { foo } from "package" in your Functions files.

where would the packages dir live for functions, am I just not understanding how the functions dir works? Do they just live alongside each function?

They will all be available, yes, but only the ones you explicitly import(and their dependencies) will actually be included in your Functions.

Hello, I enabled functions and Static Forms Pages Plugin. Now Cloudflare rewrites the Javascript in my static assets (replacing

.innerHTML="<form></form><form></form>"

.innerHTML="<form></form><form></form>"

.innerHTML="<form></form><form></form>"

.innerHTML="<form></form><form></form>" by

.innerHTML="<form method="POST"><input type="hidden" name="static-form-name" value="null" /></form><form method="POST"><input type="hidden" name="static-form-name" value="null" /></form>"

.innerHTML="<form method="POST"><input type="hidden" name="static-form-name" value="null" /></form><form method="POST"><input type="hidden" name="static-form-name" value="null" /></form>"

.innerHTML="<form method="POST"><input type="hidden" name="static-form-name" value="null" /></form><form method="POST"><input type="hidden" name="static-form-name" value="null" /></form>"

.innerHTML="<form method="POST"><input type="hidden" name="static-form-name" value="null" /></form><form method="POST"><input type="hidden" name="static-form-name" value="null" /></form>"

). Obviously this breaks the JS + the computation of the integrity hash, and I don’t see the point of this rewrite as this file is completely unrelated to functions. Is there a config flag I missed?

charelf•9/23/23, 9:13 AM

I have a CF page and Im stuck. In one of my pages functions, I do:

import { jsPDF } from 'jspdf'

import { jsPDF } from 'jspdf'

import { jsPDF } from 'jspdf'

import { jsPDF } from 'jspdf' and I ran

npm install jspdf

npm install jspdf

npm install jspdf

npm install jspdf and my page function works fine locally. My package.json also mentions this dependency. But when I push to my github to deploy, I see in the cloudflare dashboard
