ERR_INVALID_URL in npm usually happens when npm tries to parse an invalid URL from configs or the lock file (most often: registry, proxy/https-proxy, or a broken link in package-lock.json).

Quick checks (Windows PowerShell)
1Fix the registry
npm config get registry
npm config set registry https://registry.npmjs.org/

2Reset proxy settings (if they are set or broken)
npm config delete proxy
npm config delete https-proxy

3Clear lock file and cache, reinstall
del package-lock.json
rmdir /S /Q node_modules
npm cache clean --force
npm i

If that doesn’t help
Check your .npmrc (both in the project and in %UserProfile%.npmrc) — make sure there are no extra quotes, spaces, or lines like
registry="https://registry.npmjs.org" --> remove the quotes.

If you use a private registry (Azure Artifacts/GitHub Packages), make sure the URL is correct and/or set it with @scope:registry=https://….

Search package-lock.json for broken URLs:
findstr /I /C:""resolved"" package-lock.json

URLs like http:/... (with only one slash) or empty strings are a red flag — delete the lock file and reinstall (npm i).

That error usually means your npm registry URL is broken.
Run:

bash
Copy
Edit
npm config delete registry
npm config set registry https://registry.npmjs.org/
Then clear cache:

bash
Copy
Edit
npm cache clean --force
Retry your install.

That ERR_INVALID_URL in npm usually means that somewhere in your npm configuration (or in the package you're trying to install), there’s a URL that’s malformed — e.g., missing a protocol like https://, having an extra slash, or being empty.

Here’s how you can troubleshoot step by step:

---

1️⃣ Check your npm registry and config
Sometimes the registry URL gets corrupted in your npm settings.
Run:

npm config get registry

Expected output:

https://registry.npmjs.org/

If it’s anything else (or looks incomplete), reset it:

npm config set registry https://registry.npmjs.org/

Also check all your config values for stray URLs:

npm config list

If you see anything suspicious (like a file path or incomplete URL in place of a URL), correct or remove it with:

npm config delete <key>

---

2️⃣ Check your .npmrc files
npm settings can live in different places:

• Global: %AppData%\npm\etc\npmrc (Windows)
• User: C:\Users\<YourName>\.npmrc
• Project: <project-folder>\.npmrc

Open each .npmrc and look for entries like:

registry=...
proxy=...
https-proxy=...

Make sure they’re complete URLs (start with http:// or https://).

---

3️⃣ Clear npm cache
If a cached bad URL is being used:

npm cache clean --force

---

4️⃣ Check your install command
If you were running something like:

npm install <something>

Make sure the <something> is a valid package name or full valid URL. For example, this will fail:

npm install github:user/repo

if github: isn’t configured right. You may need:

npm install git+https://github.com/user/repo.git

---

5️⃣ If behind a proxy
If you use a corporate network with a proxy, check:

npm config get proxy
npm config get https-proxy

If they show something invalid (empty or missing http://), reset them:

npm config delete proxy
npm config delete https-proxy

Thank You all of you
The error was that i was mistakenly set HTTP_PROXY and HTTPS_PROXY to HTTP_PROXY=http://proxy-server:port
HTTPS_PROXY=http://proxy-server:port
To fix it I just remove both values from System Env
Here is Steps
Press Win + R → type sysdm.cpl → press Enter.

Go to Advanced → Environment Variables.

In both User variables and System variables, look for:

HTTP_PROXY

HTTPS_PROXY

Select each one → click Delete → OK.

Close and reopen your terminal/VS Code.
