Global identifiers from different JavaScript environments
It's just a JSON file, so use it in any environment.
This package is used by ESLint.
This package no longer accepts new environments. If you need it for ESLint, just create a plugin.
$ npm install globals
const globals = require('globals');
console.log(globals.browser);
/*
{
addEventListener: false,
applicationCache: false,
ArrayBuffer: false,
atob: false,
…
}
*/
Each global is given a value of true
or false
. A value of true
indicates that the variable may be overwritten. A value of false
indicates that the variable should be considered read-only. This information is used by static analysis tools to flag incorrect behavior. We assume all variables should be false
unless we hear otherwise.
For Node.js this package provides two sets of globals:
globals.nodeBuiltin
: Globals available to all code running in Node.js.
These will usually be available as properties on the global
object and include process
, Buffer
, but not CommonJS arguments like require
.
See: https://nodejs.org/api/globals.htmlglobals.node
: A combination of the globals from nodeBuiltin
plus all CommonJS arguments ("CommonJS module scope").
See: https://nodejs.org/api/modules.html#modules_the_module_scopeWhen analyzing code that is known to run outside of a CommonJS wrapper, for example, JavaScript modules, nodeBuiltin
can find accidental CommonJS references.
