mysmall-wallet

My small wallet is a simple project initially written for a challenge. This project, contains two main APIs:

● get-balance: This API should return a JSON to show the current balance of a user. The parameter which is needed for this API is user_id and the output should be like the below sample:

Input : user_id int
Output : {"balance":4000}

● add-money: This API should add money to the wallet of a user and at the end return the transaction reference number. The parameter which is needed for this API is user_id and amount and the output should be like the below sample:

Input: user_id int amount int (this parameter can be negative)
Output: {"reference_id":12312312312}

There is also an scheduling feature implemented which calculates total amount of transaction done in a day and print it out in the terminal.

How to run?

This application is going to be dockerized soon but till then, if you have go 1.18 installed, simply clone the project, cd to the project dir and type out these following instructions:

go mod tidy
go mod vendor

after this, you will have all dependancies installed. Now, for running the application simply type out the following command

You also need a mysql database to run migrations on. You can set up your database and schema preferences in envs/evs.json
