indexnowkit 0.1.0

indexnowkit

Build and validate IndexNow submission payloads in D.

IndexNow is a small protocol: you POST a JSON body naming a host, a key and a list of changed URLs, and participating search engines pick it up. The failure mode is that a malformed batch simply does nothing — you get an HTTP response and no indication that the payload was wrong. This library refuses to emit a payload it cannot prove is well formed.

Built for the deploy step of aiwebsitepipeline.com, where a static site is generated and then has to announce a few hundred URLs without a human checking each batch.

What it enforces

Straight from the protocol documentation:

• the key is 8–128 characters, drawn only from a-z, A-Z, 0-9 and -
• every URL in one submission belongs to the same host
• at most 10,000 URLs go in one POST
• the key file, when named, lives on the same host as the URLs

Usage

import indexnowkit;

auto batches = chunkUrls(allUrls, 1_000);
foreach (batch; batches)
{
    auto sub = buildSubmission(key, batch,
        defaultKeyLocation("https", "example.com", key));
    string body_ = toJson(sub);
    // POST body_ to https://api.indexnow.org/indexnow
}

Produces exactly the document shape shown in the protocol docs:

{"host":"example.com","key":"abcdef12","urlList":["https://example.com/url1"]}

For the one-off case there is the GET form:

auto url = singleUrlEndpoint("api.indexnow.org", "https://example.com/a b", key);
// https://api.indexnow.org/indexnow?url=https%3A%2F%2Fexample.com%2Fa%20b&key=...

API

Everything that can fail throws IndexNowException with a message naming the offending value — a mixed-host batch reports both hosts, for instance — rather than dropping the bad entry and sending a batch you did not intend.

Tests

dub test --compiler=ldc2

Nine unittest blocks covering key validation, URL host extraction (scheme, userinfo, port, case), mixed-host rejection, the exact JSON body, escaping of quotes/backslashes/control characters, and batch chunking that loses nothing.
