VSCode extension to integrate JavaScript Standard Style into VSCode.

We support JavaScript Semi-Standard Style too, if you prefer keeping the semicolon.

How to use

  1. Install the 'JavaScript Standard Style' extension

    If you don't know how to install extensions in VSCode, take a look at the documentation.

    You will need to reload VSCode before new extensions can be used.

  2. Install standard or semistandard

    This can be done globally or locally. We recommend that you install them locally (i.e. saved in your project's devDependencies), to ensure that other developers have it installed when working on the project.

  3. Disable the built-in VSCode validator

    To do this, set "javascript.validate.enable": false in your VSCode settings.json.

Plugin options

We give you some options to customize vscode-standardjs in your VSCode settings.json.

Option Description Default
standard.enable enable or disable JavaScript Standard Style true
standard.run run linter onSave or onType onType
standard.autoFixOnSave enable or disable auto fix on save. It is only available when VSCode's files.autoSave is either off, onFocusChange or onWindowChange. It will not work with afterDelay. false
standard.nodePath use this setting if an installed standard package can't be detected. null
standard.validate an array of language identifiers specify the files to be validated ["javascript", "javascriptreact"]
standard.workingDirectories an array for working directories to be used. []
standard.semistandard You can use semistandard if you set this option to true. Just make sure you've installed the semistandard package, instead of standard. false
standard.usePackageJson if set to true, JavaScript Standard Style will use project's package.json settings, otherwise globally installed standard module is used false

Configuring Standard

You can still configure standard itself with the standard.options setting, for example:

"standard.options": {
	"globals": ["$", "jQuery", "fetch"],
	"ignore": [
	"plugins": ["html"],
	"parser": "babel-eslint",
	"envs": ["jest"]

It's recommended to change these options in your package.json file on a per-project basis, rather than setting them globally in settings.json. For example:

"standard": {
	"plugins": ["html"],
	"parser": "babel-eslint"

If you've got multiple projects within a workspace (e.g. you're inside a monorepo), VSCode prevents extensions from accessing multiple package.json files.

If you want this functionality, you should add each project folder to your workspace (File -> Add folder to workspace...). If you can't see this option, download the VSCode Insiders Build to get the latest features.


When you open the Command Palette in VSCode (⇧⌘P or Ctrl+Shift+P), this plugin has the following options:

  • Fix all auto-fixable problems - applies JavaScript Standard Style auto-fix resolutions to all fixable problems.
  • Disable JavaScript Standard Style for this Workspace - disable JavaScript Standard Style extension for this workspace.
  • Enable JavaScript Standard Style for this Workspace - enable JavaScript Standard Style extension for this workspace.
  • Show output channel - view the linter output for JavaScript Standard Style.


  1. How do I lint script tags in vue or html files?

    You can lint them with eslint-plugin-html. Make sure it's installed, then enable linting for those file types in your settings.json:

    "standard.validate": [
    "standard.options": {
    	"plugins": ["html"]
    "files.associations": {
    	"*.vue": "html"

    If you want to enable autoFix for the new languages, you should enable it yourself:

    "standard.validate": [
    		"language": "html",
    		"autoFix": true
    "standard.options": {
    	"plugins": ["html"]

How to develop

  1. Fork this repo, and clone your fork locally.
  2. Run npm install right under project root.
  3. Open project in VSCode. The plugin should be disabled whilst developing.
  4. Run the watch build task (⇧⌘B or Ctrl+Shift+B) to compile the client and server.
  5. To run/debug the extension, use the Launch Extension launch configuration (from the VSCode debug panel).
  6. To debug the server, use the Attach to Server launch configuration.

How to package

  1. Run npm install,
  2. Run npm run compile,
  3. Run npm run package to build a .vsix file, then you can install it with code --install-extension vscode-standardjs.vsix.
