# Quick Parsing

1

2

Simple one-line parsing functionality for extracting React component documentation with default TypeScript configurations.

3

4

## Capabilities

5

6

### Parse Function

7

8

Parses React component files with default TypeScript options and returns component documentation.

9

10

```typescript { .api }

11

/**

12

* Parses a file with default TS options

13

* @param filePathOrPaths - Component file path(s) that should be parsed

14

* @param parserOpts - Options used to parse the files

15

* @returns Array of component documentation objects

16

*/

17

function parse(

18

filePathOrPaths: string | string[],

19

parserOpts: ParserOptions = defaultParserOpts

20

): ComponentDoc[];

21

```

22

23

**Usage Examples:**

24

25

```typescript

26

import { parse } from "react-docgen-typescript";

27

28

// Parse a single file

29

const docs = parse("./src/Button.tsx");

30

31

// Parse multiple files

32

const docs = parse([

33

"./src/Button.tsx",

34

"./src/Input.tsx",

35

"./src/Modal.tsx"

36

]);

37

38

// Parse with options

39

const docs = parse("./src/Button.tsx", {

40

savePropValueAsString: true,

41

shouldExtractLiteralValuesFromEnum: true,

42

propFilter: {

43

skipPropsWithName: ['className', 'style']

44

}

45

});

46

```

47

48

### Default Parser Options

49

50

The default parser options used when none are specified.

51

52

```typescript { .api }

53

const defaultParserOpts: ParserOptions;

54

```

55

56

### Default TypeScript Compiler Options

57

58

The default TypeScript compiler options used by the parse function.

59

60

```typescript { .api }

61

const defaultOptions: ts.CompilerOptions;

62

```

63

64

The default options include:

65

66

```typescript

67

{

68

jsx: ts.JsxEmit.React,

69

module: ts.ModuleKind.CommonJS,

70

target: ts.ScriptTarget.Latest,

71

esModuleInterop: true

72

}

73

```

74

75

## Component Detection

76

77

The parser automatically detects various types of React components:

78

79

- **Function Components**: Regular function declarations and arrow functions

80

- **Class Components**: Classes extending React.Component or React.PureComponent

81

- **Forward Ref Components**: Components wrapped with React.forwardRef

82

- **Memo Components**: Components wrapped with React.memo

83

- **Higher-Order Components**: Components returned from HOC patterns

84

- **Styled Components**: Components created with styled-components library

85

86

## Error Handling

87

88

The parse function will throw errors in the following cases:

89

90

- **File Not Found**: When specified file paths don't exist

91

- **TypeScript Compilation Errors**: When TypeScript cannot compile the source files

92

- **Invalid Component Syntax**: When component definitions are malformed

93

94

```typescript

95

import { parse } from "react-docgen-typescript";

96

97

try {

98

const docs = parse("./src/Component.tsx");

99

console.log(docs);

100

} catch (error) {

101

console.error("Parsing failed:", error.message);

102

}

103

```
