Development

Dependencies

It is required that an ffmpeg binary is available in the current path.

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

Code generation

To regenerate 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 regenerate the database access layer, first install sqlc. New queries can be added to backend/sql/queries.sql, and code regenerated with:

cd backend/
sqlc generate

Mocks require mockery to be installed, and can be regenerated with:

go 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
