Go HTTP handlers using context.
go get github.com/ernestoalejo/context-handler- Pass context to all handlers.
- Buffer responses to return errors to users correctly.
- Read and write JSON in POST requests easily.
- Return errors easily from the handler.
- Show stack traces of errors in stderr (compatible with App Engine).
- Configurable middlewares.
- Auto load App Engine context from the request.
- Graceful HTTP listener.
- Use
ginin development to autoreload the server.
