ESLint v6.0.0-rc.0 released

ESLint v6.0.0-rc.0 released

Summary

ESLint v6.0.0-rc.0 released
We just pushed ESLint v6.0.0-rc.0, which is a new prerelease version for ESLint v6. This release adds some new features and fixes several bugs found in the previous release. This release also has some breaking changes, so please read the following closely.
Highlights
This is a summary of the major changes you need to know about for this version of ESLint.
  1. BigInt and dynamic import are at stage 4 (aside from some TC39 formalities), so we have begun to accept PRs to incorporate them into core ESLint rules. The valid-typeof rule now supports BigInt. Please see #11803 to track our progress in fully supporting these newly standardized language features.
  2. The sort-keys rule now supports a minKeys option.

Installing

Since this is a pre-release version, you will not automatically be upgraded by npm. You must specify the next tag when installing:
npm i eslint@next --save-dev
You can also specify the version directly:
npm i [email protected] --save-dev

Migration Guide

As there are a lot of changes, we’ve created a migration guide describing the changes in great detail along with the steps you should take to address them. We expect that most users should be able to upgrade without any build changes, but the migration guide should be a useful resource if you encounter problems.
