lambda-remote-config v0.1.0

lambda-remote-config

Description

Load JSON configuration files from AWS S3 into your Lambda function. It provides a handler that process the Lambda invocations once the configuration is loaded.

Usage

var lambdaConfig = require('lambda-remote-config');

var CONFIG = lambdaConfig.fetch({ S3Bucket: 'some-bucket', S3File: 'somefile.json' });

exports.handler = lambdaConfig.handler(function (event, context) {
  // This is your actual lambda invocation handler that will be executed
  // once the configuration is loaded into the CONFIG object
});

If an error occurs, lambdaConfig will emit an error event, but the handler will be run regardless. If there is no listener for the error event, an exception will be thrown.

When the configuration is loaded successfully, and before calling the handler method, lambdaConfig will also emit a ready event.

ToDo

• Add some tests
• Introduce some retry mechanism for retriable errors
• Load config from remote urls
• Load config from a DynamoDB table
