eslint-parallel's Issues

cannot read config file

eslint ff/static/modules --ext .tsx works but eslint-parallel ff/static/modules --ext .tsx does not.

node version: 12.18.1
OS version: ubuntu 18.04.4 LTS

eslintrc:

// code code code
// bla bla bla
// more irrelevant code
module.exports = {
 // stuff
};

v1.2.0: Lint failures throw due to breaking change in chalk

The update of chalk in da83a40 has caused failing lint tasks to throw an error:

eslint-parallel/lib/formatter.js:46
        return _chalk.default.stripColor(str).length;

TypeError: _chalk.default.stripColor is not a function

Due to use of an undocumented, and now removed function in chalk:

https://github.com/pgAdmin/eslint-parallel/blob/master/src/formatter.js#L49

See this issue for context and possible solution chalk/chalk#119

does not throw exit 1 when lint fails

tried npm run lint and it returns exit code 0 when eslint fails

v1.2.1: CLI throws with ERR_REQUIRE_ESM from strip-ansi

Node: v14.16.1
eslint-parallel: 1.2.1

Caused by #25

Running eslint-parallel src/app/ --ext js
throws the following error:

internal/modules/cjs/loader.js:1080
      throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
      ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: node_modules/eslint-parallel/node_modules/strip-ansi/index.js
require() of ES modules is not supported.
require() of node_modules/eslint-parallel/node_modules/strip-ansi/index.js from node_modules/eslint-parallel/lib/formatter.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from [...]/node_modules/eslint-parallel/node_modules/strip-ansi/package.json.

Looks like the babel transformed eslint-parallel lib/formatter.js uses require and the strip-ansi module setting forbids it.

Babel 7 support

when will eslint-parallel support babel 7

Passing directories results in all non-js files being globbed

For example, running eslint-parallel ./src will attempt to lint all files under src, whether they be JavaScript or not.

Replacing ./src with ./src/**/*.js will attempt to lint files specified in .eslintignore, causing warnings.

Eslint itself has a utility for constructing the necessary globs, see https://github.com/eslint/eslint/blob/4def8764273e7cc53c71f0dd67da271636e4c1be/lib/util/glob-util.js#L47-L53. It doesn't look like it's exported from the package, but it's a small piece of code to reproduce.

slower than eslint

I've tried to run this

eslint ran in 3 minutes
and eslint-parallel ran in 4 minutes

is there any benchmark about it?
