Configuring your Express.js app for deployment bin folder created by the Express generator.

Your app does not need to listen to a TCP port because API Gateway will handle the web requests.

#NPM SERVERLESS DOMAIN MANAGER INSTALL#

Now install all project dependencies: npm install This creates a new Express project called claudia-demo, which is then placed inside of the claudia-demo directory: cd claudia-demo

#NPM SERVERLESS DOMAIN MANAGER GENERATOR#

The Express generator is a CLI that allows you to run the express command in your terminal: express claudia-demo Install the Express.js app generator using npm: npm install express-generator -g Claudia will use this profile to deploy your app to Lambda: $ aws configureĪWS Access Key ID : Your Access Key IDĪWS Secret Access Key : Your screet key Now, install the AWS CLI and use it to configure a local profile.

IAMFullAccess is required if you want Claudia.js to automatically create execution roles for your Lambda function (recommended for beginners).

AWSLambdaFullAccess is required for all Claudia.js deployments.

On the Permissions tab, add the following permission:.

Click on the Users tab and select the newly added user.

Download the credentials as a CSV and store the file in a safe location.

Secret access key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY.

Your credentials will look something like this: You won’t have access to the secret access key again after this dialog box closes. To view the new access key pair, choose Show.

At the last prompt, you’ll see new user credentials.

Create a new user, choose the Programmatic access option and follow the rest of the prompt.

Now that you have an AWS account, you’ll need to create a new user and give the user programmatic access to your AWS account.

Follow th is guide to set up your AWS account Configuring AWS access credentials Amazon has a free tier plan, which will cover creating and testing the Express.js app in Lambda. If you don’t already have an AWS account, you’ll need to create one. If the installation works as expected, you’ll see a version number similar to the one below: 5.13.0 Verify that Claudia.js was installed correctly by running the following command: claudia -version This will make Claudia.js instantly available to all your projects. The simplest way to use Claudia.js is to install it as a global utility: npm install -g claudia

In this section, we’ll walk you through setting up an example Node.js and Express.js app to show Claudia.js in action. It automates deployment tasks so you don’t need to worry about introducing errors and configures everything the way you would expect it to be set up out of the box.Īccording to the official website, Claudia’s primary objective is to help JavaScript developers get started using Lambda microservices easily so they can “focus on solving important business problems instead of dealing with AWS deployment workflows.” Getting started with Claudia.js What is Claudia.js?Ĭlaudia.js is a tool designed to simplify deployment of Node.js projects to AWS Lambda and API Gateway. So if you want to use it to host something like an Express app, you’ll need to use an adapter like Claudia.js.

Lambda expects your code to be structured a certain way. The tutorial assumes that you’re conversant with Node.js, Express.js, and Lambda.

#NPM SERVERLESS DOMAIN MANAGER HOW TO#

We’ll show you how to build and deploy an Express.js application to AWS Lambda. In this tutorial, we’ll demonstrate how to use Claudia.js to deploy a serverless API to AWS. That’s where an adapter such as Claudia.js comes in.Ĭlaudia.js sits between AWS Lambda and your Express.js app and converts Lambda invocation events from various AWS sources, such as API gateways or application load balancers, into HTTP events that your Express app can listen to. However, Lambda doesn’t have direct support for frameworks such as Express.js built with programming languages such as Node.js. Running your Express.js API on AWS Lambda is a great way to take advantage of all these benefits. Why go serverless? The benefits of deploying a serverless API include auto-scalling, zero server administration, the ability to pay only for what you use, increased velocity, etc.

It supports most popular programming languages, including Node.js. Deploying a serverless API to AWS with Claudia.jsĪWS Lambda is a serverless technology that lets you run code without provisioning or managing servers. 追加した lambda/todos/delete.jsを serverless.Godwin Ekuma Follow I learn so that I can solve problems.
