Clipper

Clipper is a Youtube audio clipper developed using modern web technologies.

• Go
• protobuf, grpc-web
• Typescript
• React

It is currently in early development.

Development

Code generation

To generate protobuf code and GRPC stubs, first install protoc and the GRPC dependencies:

go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

Then generate the code with:

./protogen.sh

To generate the database access layer, first install sqlc.

cd backend/
sqlc generate

Migrations

Database migrations require golang-migrate.

go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest

Migrations then can be run with:

cd backend/
migrate -path sql/migrations -database $DATABASE_URL up

Running the app

The backend requires configuration via environment variables - see backend/.env.example. All variables must be set unless they are marked as optional.

Then, the server can be started with:

cd backend/
go run cmd/clipper/main.go

The frontend can be launched on localhost:3000 with:

cd frontend/
yarn start
