- Minimum version of TypeScript version is now 2.1.0 (#2425)
- The severity level of rules are now configurable and defaults to severity "error". This affects the output of formatters:
- [formatter]
msbuild
was outputting all failures as "warning". - [formatter]
pmd
was outputting all failures as priority 1. Now, it uses priority 3 for "error" (default) and priority 4 for "warning"
- [formatter]
- [formatter]
json
changed thefix
property to now contain either one replacement or an array of replacements (#2403) tslint:recommended
configuration updated withtslint:latest
rules & options (#2424)- Removed
no-unused-new
rule, with logic moved intono-unused-expression
(#2269) no-trailing-whitespace
now checks template strings by default. Use the new optionsignore-template-strings
to restore the old behavior. (#2359)
-
Removed method
skip
fromRuleWalker
(#2313) -
Removed all use of the TypeScript Language Service, use only Program APIs instead (#2235)
-
This means that some rules that previously worked without the type checker now require it. This includes:
no-unused-variable
no-use-before-declare
-
This breaks custom rule compilation. If your rule was not using the
ts.LanguageService
APIs, the migration is quite simple:
- public applyWithProgram(srcFile: ts.SourceFile, langSvc: ts.LanguageService): Lint.RuleFailure[] { - return this.applyWithWalker(new Walker(srcFile, this.getOptions(), langSvc.getProgram())); + public applyWithProgram(srcFile: ts.SourceFile, program: ts.Program): Lint.RuleFailure[] { + return this.applyWithWalker(new Walker(srcFile, this.getOptions(), program));
- N.B. If you are refactoring your custom rules, consider these performance tips for writing custom rules.
-
-
Removed
createFix
. Replacements should be passed directly into addFailure. (#2403) -
Removed deprecated
scanAllTokens
andskippableTokenAwareRuleWalker
(#2370)
-
[feature] The severity level of rules are now individually configurable. Default severity can also be configured. (#629, #345)
- Valid values for
severity
:default
|error | warn | warning | none | off
- Valid values for
defaultSeverity
:error | warn | warning | none | off
- Old style:
{ "extends": "tslint:latest", "rules": { "callable-types": true, "max-line-length": [true, 140] } }
- New style (in this example,
callable-types
outputs errors andmax-line-length
outputs warnings):
{ "extends": "tslint:latest", "defaultSeverity": "error", "rules": { "callable-types": true, "max-line-length": { "options": 140, "severity": "warning" } } }
