The new implementation introduces a hard dependency on a third-party wrapper and assumes a specific JSON shape without validation; this can lead to confusing undefined returns instead of clear failures. The unconditional console.warn() on alias creates noisy side effects for a library API and should be made opt-in or once-per-process. Tests currently contradict the documented behavior by asserting aliases still affect the output, masking the breaking behavioral change. Ignoring package-lock.json is a questionable repository policy that can reduce install reproducibility.
Summary of changes
What changed
- Migrated the URL shortener implementation from scraping TinyURL HTML via
cors-anywhere.herokuapp.comto a JSON-based POST call tohttps://tinyurl-rest-wrapper.onrender.com/usingaxios.post(). - Added a runtime deprecation notice: when
aliasis provided, the function logs aconsole.warn()explaining the alias will be ignored. - Simplified tests by removing the HTML fixture + DOM/
cheerioparsing and instead mocking the wrapper’s JSON response ({ tinyurl: "..." }). - Updated
.gitignoreto ignorepackage-lock.json.

shortenUrl() now emits console.warn() whenever an alias is passed. For a library function, this creates unavoidable side effects for consumers (noise in tests/CI logs, potentially breaking apps that treat warnings as failures).
Given alias is intentionally ignored, the more appropriate path is usually either:
- soft-deprecate without logging (document it in README/CHANGELOG), or
- provide an opt-in way to warn (e.g.,
options: { onAliasIgnored }orsilent: true), or - warn only once per process (to limit log spam).
Right now, calling shortenUrl(url, alias) in a loop could flood logs.
Suggestion
Consider removing the unconditional console.warn() and replacing it with an opt-in/once-only mechanism.
Example (warn once):
let warnedAliasIgnored = false;
const shortenUrl = async (url, alias = "") => {
if (alias && !warnedAliasIgnored) {
warnedAliasIgnored = true;
console.warn(
"TinyURL alias parameter is not supported when using tinyurl-rest-wrapper. " +
"The alias will be ignored and a random slug will be generated instead."
);
}
// ...
};Or accept an options object:
const shortenUrl = async (url, alias = "", { warnOnAlias = false } = {}) => {
if (alias && warnOnAlias) console.warn(/* ... */);
// ...
};Reply with "@CharlieHelps yes please" if you’d like me to add a commit implementing the once-only warning (or the options-based approach).

The implementation now assumes a successful JSON response with a tinyurl field. If the wrapper returns a different shape (error payload, renamed key, transient HTML error page, etc.), the function will return undefined and fail later in consumer code with a confusing error.
Since this client is now coupled to a third-party wrapper, it should fail fast with a clear error when the expected field is missing.
Suggestion
Add a minimal runtime guard to validate the response shape and throw a descriptive error.
const { data } = await axios.post(
"https://tinyurl-rest-wrapper.onrender.com/",
{ url },
{ headers: { "Content-Type": "application/json" } }
);
if (!data?.tinyurl) {
throw new Error(
"TinyURL wrapper did not return `tinyurl` in response. " +
"The service may be down or the API contract may have changed."
);
}
return data.tinyurl;Reply with "@CharlieHelps yes please" if you’d like me to add a commit with this guard and corresponding test updates.

The "with alias" test now asserts that passing an alias returns a URL containing that alias. But the PR description says the alias is ignored and a random slug is generated. This test therefore encodes the old behavior and will either:
- pass only because the stub forces it to, masking a real breaking change, or
- mislead future maintainers into thinking aliases still work.
If the goal is backwards compatibility at the signature level (not behavior), the test should verify the alias is accepted without throwing and (optionally) that a warning is emitted.
Suggestion
Rewrite the alias test to reflect the new contract:
- it returns a valid TinyURL (stubbed), regardless of alias value
- it warns when alias is provided (or, if you implement warn-once/opt-in, assert accordingly)
Example:
it("accepts alias parameter but ignores it", async () => {
const warnStub = sinon.stub(console, "warn");
axiosPostStub.returns({ data: { tinyurl: "https://tinyurl.com/abc123" } });
const response = await shortenUrl("https://kulkul.tech", "shorted-kulkul");
expect(response).to.equal("https://tinyurl.com/abc123");
expect(warnStub.calledOnce).to.equal(true);
warnStub.restore();
});Reply with "@CharlieHelps yes please" if you want me to add a commit updating the tests to match the new alias behavior.

Ignoring package-lock.json is usually counterproductive for libraries/apps that want reproducible installs and deterministic CI. If this repo uses npm, the lockfile should typically be committed rather than ignored.
If you intentionally don’t want lockfiles, consider also ignoring yarn.lock/pnpm-lock.yaml for consistency and documenting the policy in the README.
Suggestion
Decide on a lockfile policy:
- If using npm: remove
package-lock.jsonfrom.gitignoreand commit it. - If intentionally lockfile-free: document it and ignore all lockfiles consistently.
Reply with "@CharlieHelps yes please" if you’d like me to add a commit reverting the .gitignore change (and optionally adding a short note to the README about lockfile policy).

Pull request overview
This PR migrates the URL shortening service from the defunct cors-anywhere.herokuapp.com to tinyurl-rest-wrapper.onrender.com as a response to issue #7. The migration changes from an HTML scraping approach using GET requests to a JSON API using POST requests, and deprecates the custom alias feature which is no longer supported by the underlying API.
Changes:
- API endpoint migration from cors-anywhere proxy to tinyurl-rest-wrapper service
- Request method changed from GET (HTML scraping with cheerio) to POST (JSON response)
- Added deprecation warning for the alias parameter which is no longer functional
- Updated tests to mock JSON responses instead of HTML content
- Added package-lock.json to .gitignore (appropriate for yarn-based project)

Migrating from a broken Heroku service to tinyurl-rest-wrapper.onrender.com introduces a new external dependency on Render's free tier hosting, which may have reliability concerns (cold starts, rate limits, potential downtime). Consider documenting this dependency and its limitations, or providing guidance on fallback strategies if the wrapper service becomes unavailable. The PR description mentions this was "recommended in issue comments" but doesn't address the long-term reliability or SLA of this service.

The test mock returns a custom alias URL "https://tinyurl.com/shorted-kulkul", but according to the PR description and the implementation, the actual API doesn't support custom aliases and will return a random slug. This test is misleading because it suggests the alias feature works when it doesn't. The mock should return a random slug (like "https://tinyurl.com/xyz789") to accurately reflect the actual API behavior, even though the test is kept for backwards compatibility.

The test expectation expects the custom alias "shorted-kulkul" to be in the URL, but this contradicts the PR's stated behavior that aliases are ignored and random slugs are generated. The expected value should be changed to match what the API actually returns (a random slug) to prevent false test passes that don't reflect real-world behavior.

Missing error handling for API request failures. The function doesn't handle cases where the POST request fails (network error, API down, timeout) or where the response doesn't contain the expected 'tinyurl' property. This will result in unhandled promise rejections or undefined being returned. Consider adding try-catch blocks or validating the response structure before accessing response.data.tinyurl.

No input validation for the URL parameter. The function doesn't validate whether the 'url' parameter is a valid URL, is empty, or is undefined before sending it to the API. This could lead to unnecessary API calls with invalid data. Consider adding basic validation to check if the URL is a non-empty string and optionally if it's a valid URL format.

| const validateUrl = (url) => { | |
| if (typeof url !== "string" || url.trim() === "") { | |
| throw new TypeError("The 'url' parameter must be a non-empty string."); | |
| } | |
| try { | |
| // This will throw if the URL is not valid. | |
| new URL(url); | |
| } catch { | |
| throw new TypeError("The 'url' parameter must be a valid URL."); | |
| } | |

Missing test coverage for error scenarios in the migrated API. The tests only cover successful responses but don't test error cases such as network failures, API errors, invalid responses (missing 'tinyurl' property), or responses with unexpected structure. Given that the codebase has comprehensive test coverage for happy paths, error scenarios should also be covered to ensure the function handles failures gracefully. Consider adding tests after line 47 for these error conditions.

The stub created in the 'before' hook is declared at the outer scope as 'axiosPostStub' but gets overwritten in the second test suite's 'before' hook without restoring the first one. While each test suite has its own 'after' hook that restores, if the first test suite runs and then the second one starts, the second 'before' will create a new stub before the first 'after' has run. This could cause issues with stub management. Consider declaring the stub variable within each test suite's scope, or ensure proper cleanup by using 'beforeEach' and 'afterEach' hooks instead.

The README.md documentation still shows that the alias parameter works and will produce a custom alias (line 31: "// https://tinyurl.com/shorted-kulkul"), but the PR description states that alias support has been lost. The documentation should be updated to reflect that the alias parameter is deprecated and no longer functional, or removed entirely to avoid confusing users.

Yes, the publish job only runs once per release. It's gated by the condition on line 37: This means:
The build step (line 51-52) in the publish job will only execute when you create a release, so it won't cause issues during regular development/testing. |
