Here is what I found on Amazon docs using AWS SDK:
var aws = require('aws-sdk');
var lambda = new aws.Lambda({
region: 'us-west-2' //change to your region
});
lambda.invoke({
FunctionName: 'name_of_your_lambda_function',
Payload: JSON.stringify(event, null, 2) // pass params
}, function(error, data) {
if (error) {
context.done('error', error);
}
if(data.Payload){
context.succeed(data.Payload)
}
});
You can find the doc here: http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Lambda.html
