How to make a Hapi.JS plugin / module?

Question

I am new to both Node and Hapi.js, but not for programming.

I created some simple Hapi.js servers, just for testing Joi and other plugins.

Now I'm trying to figure out how best to pack pieces of functionality in Hapi style, so we can reuse them in future projects and potentially share them with the world!

Are there any good resources to study this?

EDIT: I found some good resources, but without going into details about the plugin system.

• https://github.com/hapijs/hapi/issues/1489 - The start of the training contest
• https://github.com/otodockal/hapi-tutorial - Entry in the above contest with a section on plugins

Answer 1

I made a sample project that groups functionality into plugins, which may be what you are looking for:

If you are looking at function sharing between plugins, look at using plugin.expose, plugin.depend.

If you have any questions about this, you can raise the issue in the github project.

The latest hapijs.com website has a good introduction: http://hapijs.com/tutorials/plugins

Answer 2

For more information on hapi plugins (and generally hapi), see the following:

• Developing hapi Edge: A Rich Node.JS Framework for Applications and Services - This book is available now ( also from Amazon ), and there is a chapter on how to create a hapi plugin.
• Matt Harrison's upcoming hapi.js in action - This book is currently available in the "MEAP" (Manning Early Access Program), and soon (?) There is a chapter available in plugins ("Creating Modular Applications Using Plugins").
• hapi plugin search engine
• At the beginning of work with hapi.js , John Brett also has a chapter on creating and using plugins.

Edit 2015-10-04: In the chapter "Creating Modular Applications with Plugins" in Matt Harrison, the above-mentioned book now has a version of MEAP available.
