ESLint Extension for Nova

Provides integration with ESLint to lint your code.

Forked from ESLint by Cameron Little with new features.

Features

• Inline ESLint issue reporting
• "Low Severity" to show eslint errors as a lower level to remove a flood of red from your IDE
• "Fix All Issues" command
• "Apply a Suggestion" command (more information)
• Quick suggestion to ignore an issue
• Auto-fix on save preference
• Custom ESLint install locations
• Custom ESLint config file location
• Supports multiple file formats
• Javascript/Typescript
• HTML (requires eslint-plugin-html)
• Markdown (requires eslint-plugin-markdown)
• Vue (requires eslint-plugin-vue and the Vue extension)

Setup

To use this, follow the Getting Started with ESLint instructions. You'll need to have ESLint installed locally in your project (it should be installed in ${workspaceRoot}/node_modules/eslint). If you rely on a global or custom ESLint installation you can configure it by setting the "Path to ESLint executable" preference in Nova. This is accessible globally at Extensions > Extension Library… > ESLint > Preferences, and per-workspace at Project > Project Settings… > ESLint.

To verify you've set up correctly, run $(npm bin)/eslint ./path/to/file.js on a file and make sure the output is correct (no output if you don't expect issues, expected issues if you do).

Fork

NOTE: This is a fork of an earlier version of this plugin. See https://github.com/jsmecham/nova-eslint/pull/6 for more context on why I forked.

UPDATE: Since forking, this extension has overtaken the original in total installs. Because forked repositories have some management limitations and the code has evolved so much, I've unforked on GitHub. The original fork is present at https://github.com/apexskier/nova-eslint-forked.

UPDATE 2: The fork by Cameron Little was archived. I have decided to fork it again to continue
adding minor features to improve ESLint for my own usage.
