How to install ESlint with no npm?

I am working on enterprise computer with no internet access nor node (npm). I have downloaded ESlint manually and installed it to VS Code. Now it says that i need to use npm command for it to work, my question is how can i run ESlint globally without npm command/Node? Is it possible?

This what i get:

To use ESLint please install eslint by running npm install eslint in the workspace folder Supreme

or globally using 'npm install -g eslint'. You need to reopen the workspace after installing eslint.

after trying to set it right i get:

PS C:\inetpub\wwwroot\Supreme> eslint --init

eslint : The term 'eslint' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try

I found out my distro, Ubuntu 20.04, offers eslint through apt (although outdated, because only supports up to ES2018), so I don't need to install it through npm. Creating .eslintrc.json required me to have a package.json, however once I create the .eslintrc.* file, I can get rid of package.json.

Then I can run eslint ~/some_code.js anywhere as long as an eslintrc file is present. You can specify any eslintrc file to use by using -c, ex. eslint -c ~/.eslintrc.json some_code.js.

Sample .eslintrc.json for running code in browser, using spaces, unix linebreaks, double quotes for strings, and always semicolons:

{
    "env": {
        "browser": true,
        "es6": true
    },
    "extends": "eslint:recommended",
    "parserOptions": {
        "ecmaVersion": 2018
    },
    "rules": {
        "indent": [
            "error",
            4
        ],
        "linebreak-style": [
            "error",
            "unix"
        ],
        "quotes": [
            "error",
            "double"
        ],
        "semi": [
            "error",
            "always"
        ]
    }
}

I have created a Github repo for creating a tailored Eslint standalone binary here: Eslint-Standalone

This uses node, npm and pkg to build a eslint tool into a binary, such as an exe for win platform. You can then use that exe and copy it into your network at work with restrictions when it comes to npm.

npm is mostly just moving files around for you - if you want to install it without npm, just move the files around yourself.

E.g. go grab the latest release of eslint from github, copy it to your enterprise computer (network/flash drive?) and unpack it. Then call it directly using node path/to/bin/eslint.js.

If you have node.js installed it should work - if not, you'll need to use a similar approach to install that.

To execute it without prefixing the command with node, e.g. just eslint, you would need to install a .cmd wrapper alongside it. npm does this using cmd-shim

If you wanted to run it without having node.js installed, then you would need to package the node.js runtime and eslint together - options for this include pkg and nexe

To get VSCode to run eslint, you would need to setup a custom task runner by adding a tasks.js file to your project - e.g:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "label": "eslint-fix",
      "type": "shell",
      "command": "path/to/your/packaged/eslint --fix"
    }
  ]
}

Then you can use the Tasks: Run Task command to find and execute it - or setup a shortcut - for more details see the docs https://code.visualstudio.com/docs/editor/tasks#_custom-tasks
