Repository  -  API  -  Source

3.0.0

:warning: Breaking Changes:

  • Dropped support for typescript@<2.8.0
  • Dropped support for Node.js 4
  • Removed deprecated APIs:
    • getIdentifierText, isJsxFramgment, ImportOptions
    • deprected overloads of isModifierFlagSet, findImports and getControlFlowEnd
  • control flow related symbols can no longer be imported from 'tsutils/util/util', import directly from 'tsutils/util/control-flow' or 'tsutils/util'
  • isFunctionScopeBoundary and isBlockScopeBoundary now return a enum member of ScopeBoundary instead of a boolean
  • isFunctionScopeBoundary no longer returns a truthy value for InterfaceDeclaration, TypeAliasDeclaration

Features:

  • added utility isTypeScopeBoundary returning ScopeBoundary.Type or ScopeBoundary.ConditionalType
  • added enum ScopeBoundarySelector whose members can be used to determine if a declaration belongs to a given ScopeBoundary by using bitwise AND

Bugfixes:

  • collectVariableUsage now correctly handles infer T nested inside function signatures or mapped types
  • isCompilerOptionEnabled correctly handles skipDefaultLibCHeck and suppressImplicitAnyIndexErrors

2.29.0

Features:

  • added utility isCompilerOptionEnabled

2.28.0

Typeguards are now split into multiple submodules for each version of TypeScript (starting with 2.8.0). That means you can now import directly from "tsutils/typeguard/2.8" to get compatible declaraton files for TypeScript@2.8. For more information please read the relevant section in README.md.

Features:

  • added typeguards: isTupleType, isOptionalTypeNode, isRestTypeNode, isSyntheticExpression (currently available from "tsutils/typeguard/3.0")
  • added utility isStrictCompilerOptionEnabled

Bugfixes:
