![]() Id uuid DEFAULT uuid_generate_v4() NOT NULL,Ĭreated_at timestamp NOT NULL default now(), I will also appreciate any online resource with example. The Route code to create users and get all users are working.īut I am having challenge on how to reference the uuid when creating the id const for getting one user, deleting user or updating user i.e I am using the pg-promise library to connect to Postgres. I am using uuid for my id (also the primary key as shown in the user table below). I am trying to create CRUD for user in my web App. The file will look like before after this change: var express = require ( 'express' ) We will edit it to send out JSON in place of rendering a view. The last change in this step is on line 6 of index.js file found in the root of the project. ![]() ![]() The changes on the above file are only on lines 7 and 18 where the users’ router has been replaced with the quotes one. get ( '/', function ( req, res, next ) ) ) Īpp. Consequently, we will add routes/quotes.js file that will have the following content: const express = require ( 'express' ) To delete the generated public folder execute the following on your terminal: rm -rf public Delete unnecessary existing routes then create a new route for quotes #Īt this juncture, we will delete the unnecessary users' route found in routes/users.js. Therefore, we will delete the generated public folder as we will deal with JSON. Delete the public folder #īecause we are building a REST API for quotes for this Node.js PostgreSQL tutorial we don’t need any CSS or JS. The generated barebones Express Js app can be viewed in this pull request. You should see something similar on your browser when you hit on it: To quickly check if Express is setup correctly run the below: cd nodejs-posgresql & npm install & DEBUG =nodejs-posgresql:* npm start Your express will be set up when the command runs successfully. It will create the needed files in nodesj-postgresql directory. The other -git parameter indicates that we want to add the default. The -no-view parameter tells the generator to generate the Express app without any view like Pug. To step Express js with express-generator run the following command: npx express-generator -no-view -git nodejs-postgresql So let’s start with setting up Express js: Setup Express with express generator # We will be using cURL to run the examples.Īt this juncture, we believe that your Node.js is running fine. It will be great to read about HTTP verbs and brush up on some cURL commands too. A quick refresher on what REST APIs are would be greatly helpful at this point. We will be building a very simple REST API with Express Js that can send out some quotes. I will be using VS Code as an editor but you are free to use any code editor of your choice for this Node.js PostgreSQL tutorial. If you want to use PostgreSQL locally you should try out Docker and PostgreSQL. Of course, you should know how a relational database works. For the database we will use a free database on ElephantSQL, so please register and set up a free PostgreSQL database there.Having some knowledge of Git and GitHub will be really useful. ![]()
