Creating A Real-World CLI App With Node

  • When you run a CLI app, it consists of arguments and commands.
  • In order for our app to be useful at all, we’ll need to parse those commands ands arguments, and turn them into an object.
  • There are a few commands and arguments that are expected to be in every CLI: , and , which should obviously show help menus, and , and which should output the current app version.
  • This project setup is really awesome because if you need to add a new command, all you need to do is create a new file in the folder, add it to the switch statement and add a help menu if it has one.
  • If you’re fetching data from an API, generating content, writing files to the disk or any other process that takes more than a few milliseconds, you want to give the user some feedback that your app hasn’t frozen and is simply working hard.

Is Node.js killing PHP? – TFOT

  • In this article, we are going to address one of such burning arguments PHP vs Node.js.

Creating and Integrating a Node Lambda function with API Gateway

  • Creating and Integrating a Node Lambda function with APIGateway – In this three-part-series well look at getting a Node.js application which performs image resizing running on AWS Lambda.
  • Well Create a Lambda Function within AWS and configure an Application Gateway which is required to route HTTP requests to our Lambda Function.
  • In this first post were going to create a Lambda Function, configure the AWS CLI utility, invoke our function via CLI, create an API Gateway, configure the API Gateway to call our Lambda Function, and finally generate an HTTP request to the API Gateway and get the result back from…
  • Now that were authorized you can then attempt to invoke your function by running the command below: – $ aws lambda invoke \ – –invocation-type RequestResponse \ – –function-name Resizer \ – –region us-west-1 \ – output.txt ; cat output.txt ; rm output.txtYou should be greeted with the following output:…
  • From the screen with our API Gateway, click the Stages option on the left and then click the environment you made, such as Production on this screen we can see the complete URL to access our API Gateway.
