Discussion on: REST API Design Best Practices for Parameters and Query String Usage

View post

I don't really see the point of your criticism of the practice of having multiple URI parameters with the same name. You point out that some developers might add parameters to an overly simplistic data structure like a map, before encoding the map as URI parameters, and that they might lose data that way unless they used a more complex procedure to build the URI. That's certainly true, but it would be a silly mistake to make, and the alternative you suggest, of encoding multiple parameter values as a comma-separated string, is no less complex.

I just had a common JavaScript data structure in mind.

const filters = {
  limit: 25,
  afterDate: Date.now(),
  names: ["Kay", "Xing", "Derric"]
}

But you are probably right, doing filters.names.join(",") isn't much simpler than filters.names.map(n => "name=" + n).join("&").
