API

The package is available by importing its default function:

import parse from '@typedefs/parser'

parse(
  type: string,
): Type

Parses the type recursively. Obeys the JSDoc rules, but also supports Google Closure Compiler annotations.

_typedefsParser.FunctionType: The meta information about the function.

Name	Type	Description
args*	!Array<!_typedefsParser.Type>	The arguments of the function.
return*	_typedefsParser.Type	The return type of the function. When the value is set to null, it menas the function does not have a return. If the return was actuall null, it would be specified as return: { name: 'null' }.
this	!_typedefsParser.Type	The type of the this argument specified as function(this: Type).
new	!_typedefsParser.Type	The type of the new argument specified as function(new: Type).

_typedefsParser.Type: The representation of a type.

Name	Type	Description
nullable	boolean	Whether the type is nullable. This is defined by writing ? before the type name to state nullability and ! otherwise. The parser does not infer nullability from types being primitive and Function/function.
name	string	The name of the type.
union	!Array<!_typedefsParser.Type>	If the type is defined as a union, e.g., (string|number), contains the united types. Must include parenthesis.
record	!Object<string, _typedefsParser.Type>	If the type is a record, contains its representation. If a property of the record does not have a type, it will be set to null.
application	!Array<!_typedefsParser.Type>	The application of the type, e.g., the inner type of Object&lt;Application&gt;.
function	!_typedefsParser.FunctionType	The function info with args and return if the type is a function.
optional	boolean	If the type is returned as an optional argument of a function (function(string=)), this will be set to true.

Applications:
------------

{ nullable: false,
  name: 'Object',
  application: 
   [ { name: 'string' },
     { name: 'Promise',
       application: 
        [ { name: 'Array',
            application: [ { nullable: false, name: 'Type' } ] } ] } ] }

Unions (parenthesis are required):
---------------------------------

{ union: 
   [ { name: 'string' },
     { name: 'number' },
     { nullable: false,
       name: 'Promise',
       application: 
        [ { nullable: true,
            union: [ { name: 'string' }, { name: 'symbol' } ] } ] } ] }

Records:
-------

{ record: 
   { a: { name: 'string' },
     b: { nullable: true, name: 'number' },
     c: null,
     d: 
      { nullable: false,
        name: 'Promise',
        application: 
         [ { name: 'Array',
             application: [ { record: { e: { name: 'number' } } } ] } ] },
     f: { record: { g: { name: 'boolean' } } } } }

Functions:
---------

{ name: 'function',
  function: 
   { return: 
      { name: 'function',
        function: { return: { name: 'null' }, args: [] } },
     args: 
      [ { name: 'string' },
        { name: 'function',
          function: { return: null, args: [] },
          optional: true } ],
     this: { name: 'Type' } } }
