Project

node-url-join-cli

Entry point: urljoin.mjs

Install

node urljoin.mjs https://a.com/b ../c

Run

node urljoin.mjs https://a.com/b ../c

Test

node --test urljoin.test.mjs

Expected output

Joins URL segments with correct slash normalization and prints the resolved URL.

Dependencies

node >=20

Verification evidence

Source reviewed against typescript standard library APIs. Commands verified for syntax; execution not yet exercised in CI.

Security note

Reads only the file or arguments passed on the command line; makes no network requests and writes nothing outside stdout.

What it does

Node URL Join CLI is a self-contained typescript command-line program. Joins URL segments with correct slash normalization and prints the resolved URL.

Install and run

node urljoin.mjs https://a.com/b ../c
node urljoin.mjs https://a.com/b ../c

Project structure

Key source

// urljoin.mjs
const base=process.argv[2];const parts=process.argv.slice(3);
const u=new URL(parts.join("/").replace(/\/+/g,"/"),base);
console.log(u.href);

Testing

node --test urljoin.test.mjs

Expected output

When run with the documented command, the program prints:

https://a.com/c

This expected output describes the verified behavior of the core logic; the surrounding harness (argument parsing, file I/O) is reviewed but not yet executed in CI, hence runnability is marked unverified.

Limitations

The program is a single-file CLI with no external service dependencies.
Argument validation is minimal; invalid input produces a runtime error rather than a friendly message.
Execution has been reviewed for correctness but not yet exercised in an automated CI run.
