v0.15.0

Features:

• wotan test now validates test configurations
• Performance improvements using recently added Node.js file system features
• Improved caching of directory entries
• Work around breaking changes in TypeScript API regarding project references
• --fix now merges replacements of a single fix instead of throwing an error

v0.14.0

• Added support for Project References added in TypeScript 3.0.0
  • Correctly process tsconfig.json containing references
  • Log no warning on empty files array if there are references
  • Added -r or --references CLI option to recursively lint all references. This works similar to tsc --build but doesn't build a dependency graph. Instead it processes the projects depth-first in their specified order.
• Allow linting multiple projects in one run by specifiying -p or --project multiple times
• If a file was not found, report the projects it was searched in

Bugfixes:

• typecheck: correctly report declaration errors with "composite": true

Bugfixes:

• no-nan-compare: also detects comparing with Number.NaN

• many rules now have a detailed documentation page
• Node.js v10 is now officially supported

Bugfixes:

• await-only-promise now allows for-await-of with Iterable<PromiseLike<any>>, previously it only allowed AsyncIterable<any>
• no-duplicate-case added check for unions of literal types
• no-inferred-empty-object handles generic functions declared in JSDoc
• no-useless-assertion fixed detection if variable may be used before being assigned and thus the non-null assertion is actually necessary

• no-useless-assertion forbids definite assignment assertions on properties with computed name
• no-return-await wraps object literals returned from shorthand arrow functions in parentheses to avoid syntax errors
• no-useless-spread no longer autofixes object spread to avoid introducing duplicate key errors
• --project flag no longer causes a crash when referencing non-existent files
• valtyr correctly loads custom formatters

Thanks to @aervin for contributing.

v0.7.0

• new rule: no-unassigned-variable
• new rule: no-useless-spread (contributed by @aervin)
• new rule: return-never-call

Bugfixes:

• no-inferred-empty-object: check generic JSX elements (starting from [email protected])

• no-useless-predicate: checks comparing typeof with a variable that has a literal type: const str = 'string'; typeof 1 === str;

v0.6.0

Features:

• new rule: new-parens
• new rule: no-case-declaration
• new rule: no-duplicate-case
• new rule: no-misused-generics
