ESLint - window is not defined How to allow global variables in package json

Question

I am assigning a property to the global window object  but when I run eslint  I get this        window  is not defined       I see this here in the eslint docs      the following defines window as a global variable for code that should not trigger the rule being tested    valid            code   window alert         globals     window            I ve tried adding something like this to the package json file to have eslint allow  window  as a global variable  but I must be doing something wrong   From the docs it seems like I might need to do something like this in a separate file  but is there a way to define some allowed global variables right in the package json file

I m aware he s not asking for the inline version  But since this question has almost 100k visits and I fell here looking for that  I ll leave it here for the next fellow coder   Make sure ESLint is not run with the --no-inline-config flag  if this doesn t sound familiar  you re likely good to go   Then  write this in your code file  for clarity and convention  it s written on top of the file but it ll work anywhere       eslint-env browser      This tells ESLint that your working environment is a browser  so now it knows what things are available in a browser and adapts accordingly   There are plenty of environments  and you can declare more than one at the same time  for example  in-line      eslint-env browser  node      If you are almost always using particular environments  it s best to set it in your ESLint s config file and forget about it   From their docs      An environment defines global variables that are predefined  The   available environments are          browser - browser global variables    node - Node js global variables and Node js scoping    commonjs - CommonJS global variables and CommonJS scoping  use this for browser-only code that uses Browserify WebPack     shared-node-browser - Globals common to both Node and Browser                  Besides environments  you can make it ignore anything you want  If it warns you about using console log   but you don t want to be warned about it  just inline      eslint-disable no-console      You can see the list of all rules  including recommended rules to have for best coding practices
