Decompress

Decompress accepts request bodies sent with Content-Encoding: gzip and decompresses them before handlers and binding read them.

app.Use(middleware.Decompress())

Handlers can then read the body normally.

app.Post("/ingest", func(c *zinc.Context) error {
  var input Event
  if err := c.Bind().JSON(&input); err != nil {
    return zinc.ErrBadRequest.WithMessage("invalid JSON body").WithCause(err)
  }
  return c.NoContent()
})

Unsupported content encodings return 415 Unsupported Media Type. Invalid gzip bodies return 400 Bad Request.

A small compressed body can expand enormously. Set MaxDecompressedSize on any public endpoint to cap the decompressed size:

app.Use(middleware.DecompressWithConfig(middleware.DecompressConfig{
  MaxDecompressedSize: 4 << 20,
}))

Requests that expand past the limit return 413 Payload Too Large.
