Here is the aws documentation for a lambda in node.js
satya - 6/5/2019, 10:01:37 AM
How do you specify the invoking function in the package above?
You tell the lambda creation screen
the following
//Notice the .js is omitted
file1.someFunctionName
//the some-function-name
//will have a signature as follows
exports.someFunctionName = function(event, context, callback) {
console.log("value1 = " + event.key1);
console.log("value2 = " + event.key2);
callback(null, "some success message");
}
//the event, context, and callback
//are the lambda specific objects
//Read them up on the lambda site

Can I zip these files in windows?
yes. using the "send to compress" option in windows
But be sure not to zip the parent directory.
Choose the files and sub directories instead
Your .js file must be at the root level

Where do I upload the zip file for a lambda function?
This happens as part of the lambda function creation
Go ahead and create a new lambda function and in the process there is a place where you can upload the zip file or use an S3 location to which you may have uploaded the zip file

How come I can't find the option to specify a Zip file for lambda function creation?
The aws UI, like all other web UIs may change often
So what I write here may become false
Bottom line is that such an option is available
so look arund
But for now, you take the option as if you are writing code for it online
Once the editor window for the code shows, there is a drop down on the left that exposes the zip options once open

Here is how this screen shows up
Notice zip is not mentioned among the available options. So you have to choose for now "Author from scratch"

Roles: Further more, your lambda function...
must be assigned a role that has the permissions to be executed, write logs to the cloudwatch etc. When I know more roles as I go along I will document.
satya - 6/5/2019, 10:41:31 AM
What are roles?
Any underlying system like aws defines a set of actions. Say like make a phone call. Read contacts. See this, or see that. etch. these are fixed capabilities offered by an underlying system.
these are called actions.
these actions can be grouped into any number of roles. like action buckets.
An admin has the ability then to assign those actions (via roles) to executable programs or other users. A lambda function is an executable program.
