Go Query String

An opinionated suite of functions to help read common query strings into useful objects, mainly focused on data querying.

This particular package is primarily for the author's own use; if you want to pattern your query strings differently, this library is not for you!

Features

This package includes support for:

  • Filters filter=title eq Bolognese&filter=serves gte 4
  • Joins join=author&join=ingredient
  • Pagination limit=10&offset=5&page=3 (note: offset overrides page)
  • Sorting sort=title asc&sort=serves asc

You can read these individually or use the ReadPage() function to retrieve a convenient Page object that's easy to pass along to your querying code.

Example

package main

import (
	"net/http"

	"github.com/annybs/go/qs"
	"github.com/annybs/go/rest"
)

type Handler struct{}

func (*Handler) ServeHTTP(w http.ResponseWriter, req *http.Request) {
	page, err := qs.ReadPage(req.URL.Query(), nil)
	if err != nil {
		rest.WriteErrorJSON(w, err)
	} else {
		rest.WriteResponseJSON(w, http.StatusOK, page)
	}
}

func main() {
	http.ListenAndServe("localhost:8000", &Handler{})
}

Open http://localhost:8000 in your browser and try different query strings (per Features, above) to see an example response object. You can also enter malformed query strings, which will cause a validation error.
