Changed

2.5.0 - 2017-06-22

Re-releasing v2.4.0 after discovering that the memory leak is isolated to the memo-parser, which is more or less experimental anyway.

Added

• Autofixer for newline-after-import. (#686 + #696, thanks @eelyafi)

2.4.0 - 2017-06-02 [YANKED]

2.0.0! - 2016-09-30

Added

• Add option newlines-between: "ignore" to order (#519)
• Added no-unassigned-import rule (#529)

Breaking

• import/extensions setting defaults to ['.js']. (#306)
• import/ignore setting defaults to nothing, and ambiguous modules are ignored natively. This means importing from CommonJS modules will no longer be reported by default, named, or namespace, regardless of import/ignore. (#270)
• newline-after-import: Removed need for an empty line after an inline require call (#570)
• order: Default value for newlines-between option is now ignore (#519)

Changed

• imports-first is renamed to first. imports-first alias will continue to exist, but may be removed in a future major release.

1.14.0 - 2016-08-22

Added

Changed

Added

• Added an peerDependencies option to no-extraneous-dependencies to allow/forbid peer dependencies (#423, #428, thanks @jfmengels!).

Fixed

• newline-after-import exception for multiple requires in an arrow function expression (e.g. () => require('a') || require('b')). (#441, thanks @ljharb)

1.10.3 - 2016-07-08

Fixed

• removing Symbol dependencies (i.e. for-of loops) due to Node 0.10 polyfill issue (see #415). Should not make any discernible semantic difference.

1.10.2 - 2016-07-04

Fixed

• React Native shared config (based on comment from #283)

Fixed

• Fixed crash with newline-after-import related to the use of switch cases. (fixes #386, thanks @ljharb for reporting) (#395)

1.9.2 - 2016-06-21

Fixed

• Issues with ignored/CJS files in export and no-deprecated rules. (#348, #370)

• Make order's newline-between option handle multiline import statements (#313, thanks @singles)
• Make order's newline-between option handle not assigned import statements (#313, thanks @singles)

• Added newlines-between option to order rule (#298, thanks @singles)
• add no-mutable-exports rule (#290, thanks @josh)
• import/extensions setting: a list of file extensions to parse as modules and search for exports. If unspecified, all extensions are considered valid (for now). In v2, this will likely default to ['.js', MODULE_EXT]. (#297, to fix #267)

Fixed

• extensions: fallback to source path for extension enforcement if imported module is not resolved. Also, never report for builtins (i.e. path). (#296)

1.6.1 - 2016-04-28

Fixed

• no-named-as-default-member: don't crash on rest props. (#281, thanks @SimenB)

Fixed

• named now properly ignores the source module if a name is re-exported from an ignored file (i.e. node_modules). Also improved the reported error. (thanks to @jimbolla for reporting)
• no-named-as-default-member had a crash on destructuring in loops (thanks for heads up from @lemonmade)

1.5.0 - 2016-04-18

Added

• add no-named-as-default-member rule (#243, thanks @dmnd)

Changed

• Rearranged rule groups in README in preparation for more style guide rules

Removed

• support for Node 0.10, via es6-* ponyfills. Using native Map/Set/Symbol.

1.4.0 - 2016-03-25

Added

• Resolver plugin interface v2: more explicit response format that more clearly covers the found-but-core-module case, where there is no path. Still backwards-compatible with the original version of the resolver spec.
• Resolver documentation

Changed

• using package.json/files instead of .npmignore for package file inclusion (#228, thanks @mathieudutour)
• using es6-* ponyfills instead of babel-runtime

1.3.0 - 2016-03-20

Major perf improvements. Between parsing only once and ignoring gigantic, non-module node_modules, there is very little added time.

My test project takes 17s to lint completely, down from 55s, when using the memoizing parser, and takes only 27s with naked babel-eslint (thus, reparsing local modules).

Added

• This change log (#216)
• Experimental memoizing parser

Fixed

• Huge reduction in execution time by only ignoring import/ignore setting if something that looks like an export is detected in the module content.

1.2.0 - 2016-03-19

Thanks @lencioni for identifying a huge amount of rework in resolve and kicking off a bunch of memoization.

I'm seeing 62% improvement over my normal test codebase when executing only no-unresolved in isolation, and ~35% total reduction in lint time.

Changed

• added caching to core/resolve via #214, configured via import/cache setting

1.1.0 - 2016-03-15

Added

• Added an ignore option to no-unresolved for those pesky files that no resolver can find. (still prefer enhancing the Webpack and Node resolvers to using it, though). See #89 for details.

1.0.4 - 2016-03-11

Changed

• respect hoisting for deep namespaces (namespace/no-deprecated) (#211)

Fixed

• don't crash on self references (#210)
• correct cache behavior in eslint_d for deep namespaces (#200)

1.0.3 - 2016-02-26

Changed

• no-deprecated follows deep namespaces (#191)

Fixed

• namespace no longer flags modules with only a default export as having no names. (ns.default is valid ES6)

1.0.2 - 2016-02-26

Fixed

• don't parse imports with no specifiers (#192)

1.0.1 - 2016-02-25

Fixed

• export stage-0 shared config
• documented no-deprecated
• deep namespaces are traversed regardless of how they get imported (#189)

1.0.0 - 2016-02-24

Added

Changed

• namespace: support deep namespaces (#119 via #157)

1.0.0-beta.0 - 2016-02-13

Changed

• support for (only) ESLint 2.x
• no longer needs/refers to import/parser or import/parse-options. Instead, ESLint provides the configured parser + options to the rules, and they use that to parse dependencies.

Removed

• babylon as default import parser (see Breaking)

0.13.0 - 2016-02-08

Added

• no-commonjs rule
• no-amd rule

Removed

• Removed vestigial no-require rule. no-commonjs is more complete.

0.12.2 - 2016-02-06 [YANKED]

Unpublished from npm and re-released as 0.13.0. See #170.

0.12.1 - 2015-12-17

Changed

0.12.0 - 2015-12-14

Changed

• Ignore import/ignore setting if exports are actually found in the parsed module. Does this to support use of jsnext:main in node_modules without the pain of managing an allow list or a nuanced deny list.

0.11.0 - 2015-11-27

Added

• Resolver plugins. Now the linter can read Webpack config, properly follow aliases and ignore externals, dismisses inline loaders, etc. etc.!
