Thank you, very useful code! We need to add this to spellcheck eslint plugin somehow

my result code is:

.eslintrc.js

const npmLS = require("npmls")();
const allESLintRules = require("all-eslint-rules")({
  useEslintrc: false,
});

const { getDictionary } = require("./config/dictionary")

const dictionary = getDictionary({
  nodeModulesList: npmLS,
  allESLintRules: allESLintRules,
});

module.exports = {
  ...
  plugins: [
    ...
    "spellcheck"
  ],
  rules: {
    ...
    "spellcheck/spell-checker": ["warn", {
      ...
      skipWords: dictionary,
    }]
  },
}

const fs = require("fs");
const path = require("path");

const builtinModules = require("builtin-modules");

// https://gist.github.com/jrencz/becd1befac3f14b53039e0361087794c#gistcomment-3430019
const nodeModules = list => Array.from(new Set(
  list || []

    // Handle NPM scoped packages
    // See https://github.com/charlike/npmls/issues/3
    .map(name => name.replace(/^@/, ""))

    // Turns names delimited with various delimiters into words
    .reduce(
      (collector, name) => collector.concat(...name.split(/[_\-/.]/)),
      []
    )

    // Handle digit-ending words: foo3 -> foo
    .map(name => name.replace(/(\w+)\d+$/, "$1"))
));

const whitelist = fs.readFileSync(path.join(__dirname, "./spell.dict"))
  .toString()
  .split("\n")
  .map(word => word.replace(/\/\/.*$/, "")) // So you can add comments to the words
  .map(word => word.trim()) // Remove any leading/trailing whitespace
  .filter(word => word); // Remove any empty lines

const getDictionary = ({ nodeModulesList, allESLintRules }) => [
  ...nodeModules(nodeModulesList) || [],
  ...builtinModules || [],
  ...allESLintRules || [],
  ...whitelist || [],
];

// console.log(123123, { getDictionary });

module.exports = {
  getDictionary,
};

Next thing I want to add all Material UI components names because spellchecker dictionary does not have (seems like common) words like "snackbar", "tooltip" or "dropdown".

Okay is was easy as Object.keys(require("@material-ui/core"))
