@Adám NSP = much golfier than "New Sandboxed Posts"

I need help with NodeJS

ASCII-only

@Qwerp-Derp ok

Qwerp-Derp

Uhhh so if I write an app like this:

- webpage
  - all of my static files are here
- server.js

How do I make sure that no one can access server.js?

Mayube

set your website's root directory to /webpage/

ASCII-only

@Qwerp-Derp aren't you writing a server

Mayube

backend nodeJS files can access other files outside of what the front-end user can access, so your backend code doesn't need to be in the website's root directory

ASCII-only

11:42 AM

so you have to serve files manually anyway

Qwerp-Derp

Yeah

But I'm scared that people may be able to access server.js

I'm very new to backend BTW

ASCII-only

@Qwerp-Derp if you write you serving code right they won't be able to

Rod

@Qwerp-Derp you are using something already established or creating your own?

ASCII-only

if you want to be sure write a simple wrapper for fs that makes sure path.resolve(fs.dirname(__filename), thingClientWantsToAccess) starts with /path/to/webpage

or just use Express with express.static :P

Qwerp-Derp

So is this good enough?

app.use express.static path.join __dirname, ""

Rod

11:44 AM

@ASCII-only /path/to/webpage/../../../var/.....

Qwerp-Derp

Do I have to change the "" to path/to/webpage?

ASCII-only

@Qwerp-Derp yeah

@Rod ... that's why I used path.resolve

Rod

oh

Qwerp-Derp

Is my thing good enough though?

ASCII-only

@Qwerp-Derp change "" to "webpage"

Qwerp-Derp

11:45 AM

Cause I'm using nodemailer as well, which means I'm wiring up my email account to it

PhiNotPi

1:49 PM

@feersum hi

feersum

Hi :P

I was answering the question of "who drew NMP's avatar"

totallyhuman

Well um

Rune is technically an alias for an int32

But it is a Unicode code point

feersum

Rune does not even have to do with characters? Now it makes even less sense...

totallyhuman

> "Code point" is a bit of a mouthful, so Go introduces a shorter term for the concept: rune. The term appears in the libraries and source code, and means exactly the same as "code point", with one interesting addition.

The Go language defines the word rune as an alias for the type int32, so programs can be clear when an integer value represents a code point. Moreover, what you might think of as a character constant is called a rune constant in Go.

from here

Oh ok, I misread at first that int32's are called runes in general...

@Arjun I was going to object, but Japt does only have around 50 characters actually dedicated to methods and functions. Overloading is a miracle of modern technology

doesn't Japt generally accept most javascript though? Isn't that the whole point of it?

Shaggy

@Mayube Some JS can be used directly in JS but some has to be enclosed in $s.

@Mayube Not directly, but yes. You can use any plain JavaScript if you wrap it in dollar signs

Other than methods, though, you can use pretty much any JS in Japt (although variables have to be uppercase letters)
