From cbc8638c38bccd4ac7b787ac4d79de4bf2b6a0a0 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20Go=C5=82e=CC=A8biowski?= Date: Thu, 3 Nov 2016 00:51:34 +0100 Subject: [PATCH] Build: ESLint setup improvements 1. Use the short name of the preset in the config. 2. Run ESLint first on non-minified files. 3. Explicitly specify environments in every config file (those settings cascade which means we've been assuming a Node.js environment where we shouldn't have). --- .eslintrc-browser.json | 31 +++++++++++++++++++++ .eslintrc-node.json | 13 +++++++++ .eslintrc.json | 6 ++-- Gruntfile.js | 13 +++++++-- dist/.eslintrc.json | 5 +++- src/.eslintrc.json | 19 ++----------- test/.eslintrc.json | 20 +++++++------ test/node_smoke_tests/.eslintrc.json | 12 ++++++-- test/promises_aplus_adapters/.eslintrc.json | 5 ++-- 9 files changed, 88 insertions(+), 36 deletions(-) create mode 100644 .eslintrc-browser.json create mode 100644 .eslintrc-node.json diff --git a/.eslintrc-browser.json b/.eslintrc-browser.json new file mode 100644 index 000000000..c704209ab --- /dev/null +++ b/.eslintrc-browser.json @@ -0,0 +1,31 @@ +{ + "root": true, + + "extends": "jquery", + + // Support: IE <=9 only, Android <=4.0 only + // The above browsers are failing a lot of tests in the ES5 + // test suite at http://test262.ecmascript.org. + "parserOptions": { + "ecmaVersion": 3 + }, + + // The browser env is not enabled on purpose so that code takes + // all browser-only globals from window instead of assuming + // they're available as globals.
