Release Notes

standard/standard

v16.0.1

Compare Source

• Introduce "warning" system for disruptive rules (read more below)
• Change rule to a "warning": Require let or const instead of var (no-var) #​633

standard treats all rule violations as errors, which means that standard
will exit with a non-zero (error) exit code.

However, we may occasionally release a new major version of standard
which changes a rule that affects the majority of standard users (for example,
transitioning from var to let/const). We do this only when we think the
advantage is worth the cost and only when the rule is
auto-fixable.

In these situations, we have a "transition period" where the rule change is only
a "warning". Warnings don't cause standard to return a non-zero (error)
exit code. However, a warning message will still print to the console. During
the transition period, using standard --fix will update your code so that it's
ready for the next major version.

The slow and careful approach is what we strive for with standard. We're
generally extremely conservative in enforcing the usage of new language
features. We want using standard to be light and fun and so we're careful
about making changes that may get in your way. As always, you can
disable a rule at any time, if necessary.

v16.0.0

Compare Source

We're super excited to announce standard 16!

As with every new major release, there are lots of new rules in 16.0.0 designed
to help catch bugs and make programmer intent more explicit. This release brings
better performance, tons of bug fixes, improved JSX, React ⚛️, and Next.js support!

When you upgrade, consider running standard --fix to automatically format your
code to match the newly added rules.

❤️ If you enjoy StandardJS and want to support future releases, please
support Feross!

New features

• 🏎 Better performance: the filesystem doesn't need to be traversed multiple times! #​1023

  • Massive improvements (on the order of minutes!) for projects with huge folders which are are ignored with .gitignore

• 🌟 Support the .gitignore ignore syntax from the command line #​1117

  • In older versions, the command standard src would not lint the src/ folder
  • Instead, a glob pattern like standard src/**/*.js was required
  • This is now fixed! You can run standard src to lint the src/ folder!

• 🌟 Support relative paths from the command line in more situations (e.g. standard ../src/*.js) #​1384

• 🌟 New extensions option for linting additional extensions besides .js, .jsx, .mjs, and .cjs

  • Can be configured with the --ext command line flag or in package.json:

  • Example:

    standard --ext .ts

    {
      "standard": {
        "extensions": [".ts"]
      }
    }

• 🌟 New cache directory location, respecting XDG_CACHE_HOME preference, with fallback to ~/.cache/standard standard-engine/#​214

Changed features

• Update eslint from ~7.11.0 to ~7.12.1

• Update standard-engine from ^12 to ^14

  • Fix inaccurate --help command which indicates that bundle.js is automatically ignored when it is not anymore standard-engine/#​224
  • Remove deglob package and use built-in ESLint folder-traversal support

• Paths with square brackets (e.g. [ and ]) are no longer skipped #​1333

  • This pattern is particularly common in Next.js apps, e.g. blog/[slug].js
  • You may notice new errors in these files since they were not being linted before

• Better mono-repo support: Nested node_modules/ folders are ignored by default #​1182

• Remove eslint-plugin-standard #​1316

  • We migrated the remaining no-callback-literal rule into eslint-plugin-node
