Is JavaScript down? User reports show no current problems with JavaScript

Is JavaScript Down Right Now?

JavaScript is the language that runs in every web browser and on many servers. It has no single app to check, so JavaScript status covers its shared services. The npm registry, the Node.js download site, and docs like MDN can each go down alone. This page gathers reports from developers across that ecosystem.

When builds break worldwide at the same hour, npm is usually the shared weak point. Most projects install packages from the registry on every fresh build. A registry incident then fails thousands of builds together. The reports below help you see if the current trouble is shared or local.

Is JavaScript Down for Me or Everyone?

Start with the reports above and the npm status page. A spike in install failures across teams points at the registry. If the chart is quiet, your project setup holds the problem. Checking your Node and npm versions against the project requirements is the fastest first step. Teams often log days like that as a JavaScript outage across the ecosystem.

Why Does npm Install Keep Failing?

Network codes like ECONNRESET during install mean packages never arrived. During registry incidents this hits everyone with fresh builds. Older cached installs keep working, which hides the outage from many teams. Waiting for registry recovery is the main fix on those days.

Lockfile mismatches cause a different install failure. If the lockfile was made by an older npm, strict installs reject it. Deleting the lockfile and reinstalling from scratch fixes most cases. That also pulls newer versions, so tests matter right after.

Why Is the npm Registry Slow Today?

Registry traffic grows every year as project sizes balloon. Slow responses tend to appear during peak work hours. Metadata fetches for huge dependency trees feel it first. Builds that took two minutes can stretch to ten.

Region can change your experience a lot. Mirror regions sometimes lag behind the main service. Setting a closer mirror can cut fetch times on far side networks. Checking the npm status page tells you whether slowness is global today.

Why Does Code Break After a Package Update?

Package updates can change APIs without much warning. A new version of one library can break functions your code called. The error messages usually name the missing method. Rolling back to the previous version restores the build while you adapt.

Node version gaps break things too. A package may need a newer Node than your server runs. Those errors often mention engine requirements or odd syntax failures. Aligning versions between your laptop and server avoids this whole class of bugs.

Common JavaScript Problems and Fixes

Network errors during install

Network errors during install: Check the npm status page for a registry incident. Clear the npm cache and retry the install. If you are on a work network, the proxy may block parts of the registry. Testing from a second network shows whether the block is local.

node-gyp build failures

node-gyp build failures: Native packages need a C++ build chain on your machine. Install your system’s build tools and Python first. Then delete the modules folder and reinstall. Restart your terminal after installing the build chain so paths settle.

Not a function errors after updating

Not a function errors after updating: A package changed its API in the new version. Roll back to the version in your last working lockfile. Then read the package changelog before upgrading again. Pin the package once your code works, so surprise upgrades stop.

Packages install but will not run

Packages install but will not run: Your Node version may not match the package needs. Switch Node to the version the project names. Reinstall modules after changing versions, since some build natively. Version managers make switching painless.

Different behavior in browser and Node

Different behavior in browser and Node: Browsers and Node run different JavaScript environments. APIs like window, fetch, and modules differ between them. Check which environment the failing code actually ran in. Guard browser only calls so server runs skip them.
