12/25/2023 0 Comments Nodejs api aws postgresql![]() Well done! You should now be able to have a functional API that runs effectively on Node.js and uses a connected PostgreSQL database. A package.json is simply a file containing all the dependencies for your project: !`)) This creates a package.json in the directory in which this command is run. We can do that by simply running the following command in the terminal: npm init -y To get started, first we need to initialize our node project. Generally, it is really simple to get started with the installation of the required elements. The following software components are required before we can begin developing the API: First, we need to check that we have installed certain required software to ensure that the right environment is present for the development to take place. Getting started with development is simple. Why Use Node.js and PostgreSQL?Įven though there a range of different options available when it comes to creating an API, we are using Node.js and PostgreSQL for the sheer convenience they provide in the creation of APIs.Ĭontrary to other frameworks, we can get our API up and running in a matter of minutes thanks to the convenience afforded to us by our choice. The step-by-step instructions will help you gain a clear understanding of the process. We will explore all the required steps to set up the environment and go deeper into the actual creation of the API. We start from the basics and then delve into every step that you need to take to set up your API. Today’s tutorial digs deeper into the use of PostgreSQL to create a communicative API that works along with Node.js. The framework allows the creation of simple APIs that can be up and running in a matter of minutes. Unlike in the past, streamlined communication is now easy to have thanks to Node.js. It is critical for software systems to have a seamless communication system to mutually communicate all the important details. To be same first do npm init followed by npm install to ensure modules are installed in same directory for deployment.This article describes how you can use Node.js and PostgreSQL to create an API and provides an example for how to create a table. NOTE : npm install will install node modules in same directory under node_modules directory unless it sees a node_module directory in parent directory. Package the deployment directory into a zip file and upload to Lambda.You should see node_modules directory created in deployment directory which has multiple modules in it.Make sure your handler name is index.handler when you create it. So we need to create a deployment package and then upload it. Your case like mine falls under Advanced scenario. The console will zip up your code with the relevant configuration information into a deployment package that the Lambda service can run.Īdvanced scenario – If you are writing code that uses other resources, such as a graphics library for image processing, or you want to use the AWS CLI instead of the console, you need to first create the Lambda function deployment package, and then use the console or the CLI to upload the package. ![]() Using the console, you can edit and upload your code to AWS Lambda. Simple scenario – If your custom code requires only the AWS SDK library, then you can use the inline editor in the AWS Lambda console. You need to refer Creating a Deployment Package (Node.js)
