It is a simple authentication appplication made up of Gin, Golang-Jwt, and Postgress at the database. It creates user in database by providing input in JSON. We are able to login as the user we created. Also, we can log the user out by providing the phone number and password. It uses bcrypt to encrypt the password in Util directory.
It uses JWT for authentication. When we login to the user as we created before, a JWT token gets generated.
- Docker Desktop or Docker
- Make command installed
- Golang
- Postman
With docker in machine, we run make createpostgres which download a docker image and create a container out of it. We run make createdb to create a database named go-auth.
We are able to see the database created by make postgres and then \l.
We need to create the migrations for a table for database model. We run make migrate-addtable and create two migrate tables, which will be created in migrations directory. One causes to implement the table and other to destroy the table.
In _add_user_table.up.sql we write the structure given below.
CREATE TABLE "users" (
"id" bigserial PRIMARY KEY,
"username" varchar NOT NULL,
"email" varchar NOT NULL,
"phone" varchar NOT NULL,
"password" varchar NOT NULL
)
Here we create users with the following details.
And in _add_user_table.down.sql we write DROP TABLE IF EXISTS users;
Then, we run make migrate-up to forward the table to database.
--> Now we run go run main.go
In Postman, we select post method, provide user details with url localhost:8000/signup and
username, email, phone, password to create the user. This creates the user and saves the information in the database.
We use post method and provide the details like phone and password of saved user with url localhost:8000/login to login.
To logout, we select get method with url localhost:8000/logout and provide user phone and password to logout.
To delete user, we select get method with url localhost:8000/deleteuser and provide user phone and password to de;lete the specific user.
