Structured Field Values for HTTP parser and serializer.

Compliant with RFC 8941, Structured Field Values for HTTP.

Parsing

Specify field value and field type(list, dictionary, item) for parser.

import { parseSfv } from "https://deno.land/x/sfv_parser@$VERSION/parse.ts";
import { assertEquals } from "https://deno.land/std/testing/asserts.ts";

const result = parseSfv("sugar, tea, rum", "list");

assertEquals(result, {
  "kind": "list",
  "value": [
    {
      "kind": "item",
      "value": [
        { "kind": "token", "value": "sugar" },
        { "kind": "parameters", "value": [] },
      ],
    },
    {
      "kind": "item",
      "value": [
        { "kind": "token", "value": "tea" },
        { "kind": "parameters", "value": [] },
      ],
    },
    {
      "kind": "item",
      "value": [
        { "kind": "token", "value": "rum" },
        { "kind": "parameters", "value": [] },
      ],
    },
  ],
});

Syntax error

If field value has an invalid syntax, it may throw a SyntaxError.

import { parseSfv } from "https://deno.land/x/sfv_parser@$VERSION/parse.ts";
import { assertThrows } from "https://deno.land/std/testing/asserts.ts";

assertThrows(() => parseSfv("this, is, list", "dictionary"));
