![]() ![]() Next, we call log.Fatalln() to log the output to the console in case of any errors. Then we call app.Listen to start an HTTP server that is listening on our port. Next, we check our environment variables for a variable named PORT, and if that doesn’t exist, we assign the port to 3000. What we are doing here is creating a new fiber object with fiber.New and assigning it to the app variable. If you don’t have much experience with Go Fiber, here is a link to the Go Fiber documentation for you to check out. We start by importing the os module, the log module, and of course our web framework of choice, which in this case is Go Fiber. Log.Fatalln(app.Listen(fmt.Sprintf(":%v", port))) If I understand correctly, pgModeler shows the ER diagram of the database (portion of a database). > Use Case of Graphical Query Builder (GQB) is different from pgModeler. Without further ado, let’s get started.Ĭreate a file named server.go in your project folder and add the following code: package main Hi Patrick, > If you are looking for a GUI tool to design databases pgModeler ( > might be able to help you. This application allows us to get, add, edit and delete to-do items from our database. Basically, we will be building a to-do application. We will be building a full-stack web application that allows us to perform CRUD operations on our Postgres database. What we will be building: A simple to-do app pgAdmin 4 - this is a user interface that allows us to manage our Postgres database visually.You can download PostgreSQL from the official website here However, in production, you might consider a more robust and secure solution such as a cloud offering. So, for development purposes, you will need to install it in your local environment. PostgreSQL - we will be using PostgreSQL as our database.Go - as this is our programming language of choice, we need to install it in our local environment.Prerequisitesīefore we start working on this application, there are a few things we need to get set up: In this article, we will be looking at how we can use Postgres in a Go application. According to the official documentation, it is “a powerful, open-source object-relational database system with over thirty years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.” PostgreSQL is one of the most popular SQL databases today. Building a simple app with Go and PostgreSQL In my spare time, I enjoy watching sci-fi movies and cheering for Arsenal FC. You also have access to embedded instructions for all aspects of use including multi-database management or how to properly set up SQL triggers and execute SQL scripts.Emmanuel John Follow I'm a full-stack software developer, mentor, and writer. There is also a ‘Query Tool Macros’ for performing pre-defined SQL queries in as little as a single key press. This option enables visually building SQL queries and executing or saving them to a TXT file. PgAdmin additionally provides you with a Graphical Query Builder (GQB) option. It includes many useful features including syntax highlighting, SQL editor, procedural code debugger, and a server-side code editor to name a few. You can perform different actions like running simple SQL queries all the way up to developing complex databases. pgAdmin provides a powerful graphical interface that simplifies the creation, maintenance and use of database objects. ![]() pgAdmin is designed for both novice and experienced Postgres users alike. ![]() It allows you to write simple SQL queries or to develop complex databases all with the support of PostgreSQL functions. PgAdmin allows multi-database management through an administration interface for PostgreSQL permitting statement, procedure viewing and more. ![]()
