Release proposal: standard v10

[feross]

Planned release date: Apr 1, 2017. (approx. 29 days from the date of this issue)

Try it now: npm install standard@beta --global

New features

• Update ESLint from 3.15.x to 3.16.x.

New rules

(Estimated % of affected standard users in parens)

• Disallow using deprecated Node.js APIs (node/no-deprecated-api) #693 (13%)
  • Ensures that code always runs without warnings on the lastest versions of Node
  • 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, cb, or next must be called with null, undefined, or an Error object as the first argument
  • Prevents accidentally using a string instead of an Error object
  • Prevents confusing callbacks that do not follow the 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) (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

I decided to push the planned release date for 10.0.0-beta.0 forward by a month so we can do our part to warn users about Node deprecations long before Node itself hard-deprecates those APIs.

The largest "ecosystem breakage" is due to that change: checking for deprecated API usage.

April Fools Day Release 👍

[capaj]

next must be called with null, undefined, or an Error object as the first argument

@feross won't this cause problems for people writing koa.js-see: http://koajs.com/#cascading ?

[dcousens]

@capaj isn't that the same as undefined as the first argument?

[capaj]

@dcousens oh right, I've misinterpreted that rule.
