Function createProgram

  • createProgram(createProgramOptions): Program

  • Create a new 'Program' instance. A Program is an immutable collection of 'SourceFile's and a 'CompilerOptions' that represent a compilation unit.

    Parameters

    • createProgramOptions: CreateProgramOptions

      The options for creating a program.

    Returns Program

    A 'Program' object.

  • createProgram(rootNames, options, host?, oldProgram?, configFileParsingDiagnostics?): Program

  • Create a new 'Program' instance. A Program is an immutable collection of 'SourceFile's and a 'CompilerOptions' that represent a compilation unit.

    Creating a program proceeds from a set of root files, expanding the set of inputs by following imports and triple-slash-reference-path directives transitively. '@types' and triple-slash-reference-types are also pulled in.
