Ignore the indentation in a template literal, with the ESLint `indent` rule

To ignore all indentation and newline errors in ESLint inside a template literal, including function calls or deeply nested JS syntax, you can use "ignoredNodes": ["TemplateLiteral *"] (without the > child selector, to target all descendants.)

  "rules": {
    "indent": ["error", 2, { "ignoredNodes": ["TemplateLiteral *"] }],
    "function-paren-newline": "off"
  }

You also have to specify your normal indentation rule, e.g. "error", 2 for enforcing 2 spaces or "error", "tab" for tabs.

"function-paren-newline" was also giving errors inside my template literals, I also wanted to disable that (because I'm extending an existing ESLint config that displayed an error for that).

From looking at an ast tree with simply ${foo}, I confirmed that it is truly the TemplateLiteral node. However I happened to also know the solution from there: you need to select its children as well. This can be done with TemplateLiteral > *. The reason why your solution wasn't working is because ESLint will exempt the TemplateLiteral from the indent rules, but only the little ${ and } parts, not the contents.

This can go into your ESLintrc file as such:

"indent": ["error", "tab", { "ignoredNodes": ["TemplateLiteral > *"] }]

I'm sorry no one else was able to answer your question sooner.
