getir case study

A REST API to store and retrieve key value pairs on the fly and to interact with mongoDB.

Running on Local

[email protected]:discoverAnkit/getir.git
cd getir
./gradlew build
go run main.go

This will download all dependencies and produce a working binary in the ./build/bin subdirectory.

However, if gradle is not set up or is not working for some reason, we can always default to commands provided by Go itself to run tests and create a binary etc

Example

go build
go test ./...
go run main.go

Local Machine Requirements:

• You need Go 1.12.7 or newer (its not test for earlier versions)
• You also need JRE 8 or later to run Gradle build system (the gradle jar files are already included in repo so they won't need to be downloaded)

Dependency management

• Go modules are used to manage dependencies. Clone the project outside of the $GOPATH or set export GO111MODULE=on in your shell to enable the modules.
