v5.4.0

⭐️ Non-breaking API changes

  • The --type-check CLI option now only enables checking for compiler errors before linting. It is no longer required to enable rules that use the type checker -- only need to supply --project now.

🎉 New rules, options, and fixers

v5.0.0

NPM distribution note: tslint@next is deprecated now that the standard tslint package allows a peer dependency of typescript@next. Please switch to tslint@latest.

🔥 Breaking changes

  • Minimum version of TypeScript is now 2.1.0 (#2425)
  • The severity level of each rule is 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] json changed the fix property to now contain either one replacement or an array of replacements (#2403)
  • tslint:recommended configuration updated with tslint:latest rules & options (#2424)
  • Removed no-unused-new rule, with logic moved into no-unused-expression (#2269)
  • no-trailing-whitespace now checks template strings by default. Use the new options ignore-template-strings to restore the old behavior. (#2359)
  • Some rules that previously worked without the type checker now require it. This includes:
    • no-unused-variable
    • no-use-before-declare

API breaks for editor integration

  • LintResult.failureCount is now separated into LintResult.errorCount and LintResult.warningCount
  • class Fix is now type Fix = Replacement | Replacement[]

API breaks for custom rules

  • Removed method skip from RuleWalker (#2313)

  • Removed all use of the TypeScript Language Service, use only Program APIs instead (#2235)

    • 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));

  • Removed createFix. Replacements should be passed directly into addFailure. (#2403)

  • Removed deprecated scanAllTokens and skippableTokenAwareRuleWalker (#2370)

🎉 Notable features & enhancements

  • [feature] The severity level of each rule is now individually configurable. Default severity can also be configured for a config file. (#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 and max-line-length outputs warnings):
    {
    "extends": "tslint:latest",
    "defaultSeverity": "error",
    "rules": {
        "callable-types": true,
        "max-line-length": {
            "options": 140,
            "severity": "warning"
        }
    }
}

  • [new-rule] prefer-template (#2243)

  • [new-rule] return-undefined (#2251)

  • [new-rule] no-reference-import (#2273)

  • [new-rule] no-unnecessary-callback-wrapper (#2249)

  • [new-fixer] linebreak-style (#2394)

  • [new-fixer] eofline (#2393)
