From 3dc30632755713179f345f4af024bd904c6162d0 Mon Sep 17 00:00:00 2001 From: Michaël Zasso Date: Fri, 22 Dec 2017 16:53:42 +0100 Subject: tools: move eslint from tools to tools/node_modules This is required because we need to add the babel-eslint dependency and it has to be able to resolve "eslint". babel-eslint is required to support future ES features such as async iterators and import.meta.
