Polymorphic Node
Important: These docs are for the outdated Jets 5 versions and below. For the latest Jets docs: docs.rubyonjets.com
Important: Since Jets v5, Polymorphic support is no longer supported with Controllers. It is supported in other types of classes like Jobs though. The reason it is no longer supported in Controllers is because only one Lambda Function is used for Jets Controllers in Jets v5. The docs below will be updated in time.
To write your Jets Lambda functions in node, it would look like this:
app/controllers/posts_controller.rb:
class PostsController < ApplicationController
node :node_example
end
You add your corresponding node code in the posts_controller/node folder:
app/controllers/posts_controller/node/node_example.js:
'use strict';
exports.handler = function(event, context, callback) {
var message = 'hi from node ' + process.version;
var body = {'message': message};
var response = {
statusCode: "200",
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(body)
};
callback(null, response);
};
Notice, how with the node code, you must handle returning the proper lambda proxy structure to API Gateway.

Default Handler Name
The default node handler name is handler. The default can be changed with the handler method. Example:
app/controllers/posts_controller.rb:
class PostsController < ApplicationController
handler :handle
node :node_example
end
The node code would then look something like this:
exports.handle = function(event, context, callback) {
...
};
You can also set the handler for the entire class. Example:
class PostsController < ApplicationController
class_handler :handle
# ...
end
