JavaScript Semi-Standard Style

One Semicolon for the Dark Lord on his dark throne

All the goodness of feross/standard with semicolons sprinkled on top.

Install

npm install semistandard

Rules

Importantly:

• semicolons Check [feross/standard][1] for the rest of the rules.

What you might do if you're clever

1. Add it to package.json

{
  "name": "my-cool-package",
  "devDependencies": {
    "semistandard": "*"
  },
  "scripts": {
    "test": "semistandard && node my-normal-tests-littered-with-semicolons.js"
  }
}

1. Check style automatically when you run npm test

$ npm test
Error: Code style check failed:
  lib/torrent.js:950:11: Expected '===' and instead saw '=='.

1. Never give style feedback on a pull request again! (unless its about semicolons)

See feross/standard for more information. In fact, you should probably just use the standard module instead.

Changelog

11.0.0 2017-04-20

Updated to match the latest standard v10.0.2 rules and the newest standard-engine features.

Check standard changelog that covers all the updates: https://github.com/feross/standard/blob/master/CHANGELOG.md

In summary:

• using deprecated Node.js APIs is now considered an error. It's finally time to update those dusty old APIs!

New features

• Update ESLint from 3.15.x to 3.19.x.
• Node.js API: Add standard.lintTextSync method

New rules

(Estimated % of affected standard users, based on test suite in parens)

• Disallow using deprecated Node.js APIs (node/no-deprecated-api) #693 (13%)
  • Ensures that code always runs without warnings on the latest versions of Node.js
  • Ensures that safe Buffer methods (Buffer.from(), Buffer.alloc()) are used instead of Buffer()
• Enforce callbacks always called with Node.js-style error first (standard/no-callback-literal) #623 (3%)
  • Functions named callback or cb must be invoked with null, undefined, or an Error as the first argument
  • Disallows using a string instead of an Error object
  • Disallows confusing callbacks that do not follow the standard Node.js pattern
• Disallow any imports that come after non-import statements (import/first) #806 (1%)
• Disallow unnecessary return await (no-return-await) #695 (0%)
• Disallow comma-dangle in functions (comma-dangle) #787 (0%)
• Disallow repeated exports of names or defaults (import/export) #806 (0%)
• Disallow import of modules using absolute paths (import/no-absolute-path) #806 (0%)
• Disallow Webpack loader syntax in imports (import/no-webpack-loader-syntax) #806 (0%)
• Disallow comparing against -0 (no-compare-neg-zero) #812 (0%)

Changed rules

• Relax rule: allow using ...rest to omit properties from an object (no-unused-vars) #800
  • This is a common and useful pattern in React/JSX apps!
• Relax rule: allow Flow import type statements (import/no-duplicates) #599
  • These are no longer considered to be "duplicate imports"
• Relax rule: Treat process.exit() the same as throw in code path analysis (node/process-exit-as-throw) #699
  • Makes certain other rules work better and give fewer false positives
• Relax rule: allow Unnecessary Labels (no-extra-label)
  • Redundant, since "no-labels" is already enabled, which is more restrictive

(from standard 10.0.2):

• Relax rule: Disallow import of modules using absolute paths (import/no-absolute-path) #861
  • This rule was responsible for up to 25% of the running time of standard, so we are disabling it until its performance improves.
