Setup Instructions

Use the terminal to navigate to your playground. Example:

cd E:\

Cool now you have to make a copy of my repo.

git clone https://github.com/evelinkolev/tribe-payments-wallet-golang-interview-assignment

Open the folder in IDE of your choice. I have used VS Code with Go extension. Initialise the go.mod (only if does not exist).

go mod init tribe-payments-wallet-golang-interview-assignment

Install dependencies.

go get github.com/microsoft/go-mssqldb
go get -u github.com/golang-migrate/migrate/v4
go get -u github.com/golang-migrate/migrate/v4/database/sqlserver
go get -u github.com/golang-migrate/migrate/v4/source/file
go install -tags 'sqlserver' github.com/golang-migrate/migrate/v4/cmd/migrate@latest

Open SSMS and create database with name wallet_db. Run the migrate command. (only If you have issue with migrate like in my case, check https://github.com/golang-migrate/migrate and build the .exe file on your machine).

migrate -database "sqlserver://localhost:1433?database=wallet_db&integratedSecurity=true&trustServerCertificate=true" -path ./migrations up

Start the application

go run . api

The API will be available at: http://localhost:8080
