So, I can execute bash through TypeScript I guess 🤔

So, I can execute bash through TypeScript I guess

HHello, I’m Allie!Though you could probably make it a part of your Svelte App

The main problem is that how will CF download my dependencies?

GGetPsyched So, I can execute bash through TypeScript I guess 🤔

Hello, I’m Allie!•10/4/23, 8:05 AM

No, because Functions doesn't have a Bash interpreter.

GetPsychedOP•10/4/23, 8:05 AM

on my local system I do it using nix developnix develop

GGetPsyched The main problem is that how will CF download my dependencies?

Hello, I’m Allie!•10/4/23, 8:05 AM

During the build step

Hello, I’m Allie!•10/4/23, 8:05 AM

Or you can build it locally

HHello, I’m Allie!No, because Functions doesn't have a Bash interpreter.

GetPsychedOP•10/4/23, 8:05 AM

ah rip so I'll have to do a significant refactor

HHello, I’m Allie!Or you can build it locally

GetPsychedOP•10/4/23, 8:05 AM

huh?

GGetPsyched huh?

Hello, I’m Allie!•10/4/23, 8:06 AM

If you run the build locally with nixnix(or another build/dependency tool), then all of your dependencies will be bundled before being deployed.

GetPsychedOP•10/4/23, 8:06 AM

Oh so basically I push my pre-built stuff

GetPsychedOP•10/4/23, 8:06 AM

hmm

GetPsychedOP•10/4/23, 8:07 AM

idk if that's even possible with nix

GetPsychedOP•10/4/23, 8:07 AM

I'll check

HHello, I’m Allie!Though you could probably make it a part of your Svelte App

GetPsychedOP•10/4/23, 8:07 AM

Weird. I have bash commands that just don't exist as libraries

GGetPsyched idk if that's even possible with nix

Hello, I’m Allie!•10/4/23, 8:08 AM

I mean that was just an example. If you are using Functions, then unless you use WebAssembly, you will probably be using

npm

npm

pnpm

pnpm

yarn

yarn

bun

bun

, etc.

GetPsychedOP•10/4/23, 8:08 AM

Those things would simply be impossible?

GGetPsyched Those things would simply be impossible?

Hello, I’m Allie!•10/4/23, 8:08 AM

Not impossible, you would just have to rewrite them into JS/TS yourself

HHello, I’m Allie!I mean that was just an example. If you are using Functions, then unless you use...

GetPsychedOP•10/4/23, 8:08 AM

those don't come with those deps

HHello, I’m Allie!Not impossible, you would just have to rewrite them into JS/TS yourself

GetPsychedOP•10/4/23, 8:08 AM

yeah

GetPsychedOP•10/4/23, 8:08 AM

weird that CF doesn't support bash

GetPsychedOP•10/4/23, 8:08 AM

I guess it's for security reasons

GetPsychedOP•10/4/23, 8:09 AM

but a big bummer nonetheless

GGetPsyched weird that CF doesn't support bash

Hello, I’m Allie!•10/4/23, 8:09 AM

No, it’s just because the runtime isn’t a container or a VM

Hello, I’m Allie!•10/4/23, 8:09 AM

Which is why it is so fast

GetPsychedOP•10/4/23, 8:09 AM

makes sense

Hello, I’m Allie!•10/4/23, 8:09 AM

Like how Functions don’t have a file system

GetPsychedOP•10/4/23, 8:09 AM

yeah, gotcha

GetPsychedOP•10/4/23, 8:10 AM

so even if I push the deps from Nix to CF, it won't be able to use them since they're shell commands

GGetPsyched so even if I push the deps from Nix to CF, it won't be able to use them since th...

Hello, I’m Allie!•10/4/23, 8:10 AM

That is correct

GetPsychedOP•10/4/23, 8:10 AM

my app is literally so close to being a serverless app but not close enough

GGetPsyched my app is literally so close to being a serverless app but not close enough

Hello, I’m Allie!•10/4/23, 8:11 AM

Need a Serverless bash runtime smh

GetPsychedOP•10/4/23, 8:11 AM

lol

GetPsychedOP•10/4/23, 8:11 AM

even if I managed to do this in Svelte, the outputs may vary from what the shell script produces

GetPsychedOP•10/4/23, 8:17 AM

Can I run

bun

bun

commands at least?

GetPsychedOP•10/4/23, 8:17 AM

something like:

cd dist && bun ssr.js

cd dist && bun ssr.js

GGetPsyched Can I run `bun` commands at least?

Hello, I’m Allie!•10/4/23, 8:18 AM

Nope. No cd, no bun, no commands at all

Hello, I’m Allie!•10/4/23, 8:19 AM

Workers/Functions are their own JS Runtime, just like how Bun is different from Node

HHello, I’m Allie!Nope. No cd, no bun, no commands at all

GetPsychedOP•10/4/23, 8:21 AM

Okay, then, can I at least use https://www.npmjs.com/package/prince?

GetPsychedOP•10/4/23, 8:21 AM

It needs the prince CLI installed

GGetPsyched It needs the prince CLI installed

Hello, I’m Allie!•10/4/23, 8:23 AM

Probably not that either

GetPsychedOP•10/4/23, 8:23 AM

Ouch.

GetPsychedOP•10/4/23, 8:23 AM

there go my hopes and dreams

Hello, I’m Allie!•10/4/23, 8:23 AM

Maybe you want https://ekoopmans.github.io/html2pdf.js/

html2pdf.js

Client-side HTML-to-PDF rendering using pure JS.

GetPsychedOP•10/4/23, 8:24 AM

hmm.

GetPsychedOP•10/4/23, 8:24 AM

will likely have to tweak some stuff here

GetPsychedOP•10/4/23, 8:24 AM

thanks for the suggestion. I'll try this out later today

GetPsychedOP•10/4/23, 9:10 AM

@Hello, I’m Allie! I can't build the output files within JS though, right?

GetPsychedOP•10/4/23, 9:10 AM

my script for ref

bunx --bun vite build --ssr --log-level error
(cd dist && bun ssr.js {{PRESET}})
echo "Distributable files generated successfully!"

bunx --bun vite build --ssr --log-level error
(cd dist && bun ssr.js {{PRESET}})
echo "Distributable files generated successfully!"

GetPsychedOP•10/4/23, 9:11 AM

is there some way to run this in JS?

GGetPsyched is there some way to run this in JS?

Hello, I’m Allie!•10/4/23, 9:11 AM

I assume you are using SvelteKit, right? SvelteKit has a Pages Adapter which you can use

So, I can execute bash through TypeScript I guess 🤔
