VS Code - space before function parentheses

I'm on the VSCode team. As of VSCode 1.8, this formatting option is not supported out of the box, but we are tracking the feature: https://github.com/Microsoft/vscode/issues/15386, https://github.com/Microsoft/TypeScript/issues/12234

As a workaround, try the following:

• Install the eslint extension: ext install eslint
• Add "eslint.autoFixOnSave": true to your workspace or user settings

• In the root of your project, create an .eslintrc.json with:

  {
      ...
      "rules": {
          ...
          "space-before-function-paren": "error"
      }
  }
  

  The eslint extension can create a starter .eslintrc.json for you with the create .eslintrc.json command.

This will automatically format functions to have a space after them when you save the file.

1. In VS Code open File -> Preferences -> Settings
2. Add to your JSON config:

"javascript.format.insertSpaceBeforeFunctionParenthesis": true

function render () {
    // some code here
}

"javascript.format.insertSpaceBeforeFunctionParenthesis": false

function render() {
    // some code here
}

3. Now you can continue using your auto format option "editor.formatOnType": true

I had a similar issue with VSCode removing spaces after a constructor and ESLint complaining because there wasn't a space.

• Go to File -> Preferences -> Settings
• Search for constructor
• Add a check next to JavaScript › Format: Insert Space After Constructor

I had opposite problem with anonymous functions. We use prettier extension. Auto-correct inserts a space before parenthesis. And then prettier complains about it.

var anonfunc = function() {
    // Expected syntax. 
}

var autocorrected = function () {
    // Auto-correct inserts a space
}

There is similar code option, which solves my problem:

"javascript.format.insertSpaceAfterFunctionKeywordForAnonymousFunctions": false

By default it is true. Took me some time, until I was tired correcting auto-correct.
