Update documentation for using Crafty as a module

[0xf0xx0]

I'm helping develop a top-down game for desktop, so I need to use crafty as a module in VSCode. How can I do that? I don't see anything in the docs about this.

Have you tried using it via the npm module?

There's an example app you can look at here, though it's from a few versions ago.

Theres not much info in the README, do I have to cd into the crafty-develop folder?
EDIT: im dumb lol, I didn't realize there was a npm module. thanks! Another question: can Crafty be used outside a html file? I was reading the docs, and it seems you need a html page to use Crafty.

Also, installing craftyjs outputs a bunch of errors.

$ npm i craftyjs

> craftyjs@0.9.0 postinstall /Users/gingkathfox/node_modules/craftyjs
> (node -e "process.env.NODE_ENV !== 'production' && process.exit()" && grunt copy:lib) || node -v

This one looks like an issue with the package.config -- it's a step that's necessary when developing with crafty, but not when installing it as a module. It's getting run as a postinstall script, so even with the error it would normally mean that crafty had installed ok. However:

v8.9.4
npm WARN saveError ENOENT: no such file or directory, open '/Users/gingkathfox/package.json'

and

No package.json found: Cannot audit a project without a package.json

These errors look like you're trying to install crafty into a place that isn't set up as a node project. If you're in the folder for your project, you'll want to start by either creating a package.json file, or running npm init to create one automatically.

Another question: can Crafty be used outside a html file?

All of the rendering methods assume assume some sort of DOM/html context. It's possible to build a headless version of crafty that could run in the context of a node server, but that doesn't sound like what you're going for.

[starwed]

I think PR #1199 will fix the errors when you don't have grunt installed in the future. (But not until we release a new version on npm.)

[ExperiBass]

ok!

[starwed]

I think the main issue here is that we need better docs on using Craft as a module, so updating the title to that.

[ExperiBass]

Hmmm, yeah, that's a better title XD

@starwed the example app helped, thanks! i have another, completely different question though. Do you have a discord so we can chat?
