Requiring js with engine gem

rubyonrails-talk
1

I am having a go, for the first time, at making a gem which is an engine. I have some javascript files which I have put in the gem/app/assets/javascript. I can access those from the app but only if I require them from the apps application.js. So if I have two js files in the gem, say f1.js and f2.js, then in the apps application.js I have to put //= require f1 //= require f2

I have not been able to find a way to avoid having to require them all individually. Is this possible?

Hi Colin,

I am having a go, for the first time, at making a gem which is an

engine. I have some javascript files which I have put in the

gem/app/assets/javascript. I can access those from the app but only

if I require them from the apps application.js. So if I have two js

files in the gem, say f1.js and f2.js, then in the apps application.js

I have to put

//= require f1

//= require f2

I have not been able to find a way to avoid having to require them all

individually. Is this possible?

What I usually do is something like this:

Let’s say that I have an engine called “my_engine”, then I would create a my_engine/app/assets/javascript/index.js which would have the content:

//= require f1

//= require f2

Then in the host app’s application.js you can call

// require my_engine

This is actually a very neat trick that Rails have to load files inside a folder. It will always look for an index.js file first.

I hope this helps,

Sorry, I meant: “//= require my_engine” here.

What I usually do is something like this:

Let's say that I have an engine called "my_engine", then I would create a my_engine/app/assets/javascript/index.js which would have the content:

//= require f1 //= require f2

Then in the host app's application.js you can call

Of course! It's obvious when you know how.

Thanks
