Simple Usage

func main() {
	// create a parser
	parser := formstash.NewParser(formstash.ParserOptions{
		MaxFileSize:   5 << 20,
		MaxFileCount:  5,
		MaxParseCount: 5,
	})

	store := formstash.NewFilesystemStorage("./files")

	router := gin.Default()
	router.POST("/upload", func(c *gin.Context) {
		// parse
		request, err := parser.Parse(c.Request)
		if err != nil {
			fmt.Println(err)
		}

		// get the form
		images, err := request.GetForm("images")
		if err != nil {
			fmt.Println(err)
		}

		// save
		for key, image := range images {
			err = store.Save("images", "image_"+strconv.Itoa(key), image)
			if err != nil {
				fmt.Println(err)
			}
		}
	})
	router.Run()
}

You can use formstash with the other http server libraries, just pass the http.Request to the parser.Parse function.

Filtering Parts

You can filter parts by their properties, like part's content type. Parser can inspect the part's bytes and detect the type of the part with the Inspector.

// create a parser
parser := formstash.NewParser(formstash.ParserOptions{
	MaxFileSize:   5 << 20,
	MaxFileCount:  5,
	MaxParseCount: 5,
})

// give parser an inspector
parser.SetInspector(formstash.NewDefaultInspector(512))
// give parser a filter
parser.SetFilter(formstash.NewExtensionFilter(".jpg"))

Now parser will inspect the each part and it will just return the jpeg ones from the Parse function. You can make your own Inspector and Filter.
