scratch

Template Golang service and libraries.

Getting started

How to install

Clone scratch

git clone https://github.com/levinishka/scratch.git

You can either compile scratch by yourself:

using make

cd scratch
make build

manual

cd scratch
go build -o cmd/bin/scratch cmd/scratch/main.go # for Linux
GOOS=windows GOARCH=amd64 go build -o cmd/bin/scratch.exe cmd/scratch/main.go # for Windows

Or use precompiled binaries in cmd/bin folder:

• scratch for Linux
• scratch.exe for Windows

How to use

Check help

./cmd/bin/scratch -help

Scratch creates template for Golang service:

1. create service from scratch
   1. use -project parameter to specify new project's path: last element in a path will be new project's name
   2. use -repo parameter to specify git repository path of new project
2. initialize go modules
3. write your own logic using template service
4. test it
5. initialize git and push
6. ???
7. PROFIT

Examples

Creates new project with name testProject

# create project from scratch
chmod a+x ./cmd/bin/scratch
./cmd/bin/scratch -project /absolute/path/to/testProject -repo github.com/levinishka

# initialize go modules
cd /absolute/path/to/testProject
go mod init github.com/levinishka/testProject
go mod tidy

# write logic and then test service
make lint
make test
make build
make test-run

# initialize git and push
git init
git add --all
git commit -m "Initial Commit"
git remote add origin github.com/levinishka/testProject.git
git push -u origin master

Libraries

Scratch contains some useful libraries which you can import and use:

• config simply reads config file in JSON format and unmarshal it to a structure
• logger provides preconfigured zap-logger
• router provides mux router with pprof handlers added
• server provides http server with graceful shutdown
• metrics provides prometheus http server with basic service metrics

To import any of these packages use "github.com/levinishka/scratch/pkg/PACKAGE"
