# html5parser
A very tiny and fast html5 AST parser, the result could be manipulated like
ECMAScript ESTree, especially about the attributes.
It is a great platform for helping people in trouble.
`html5parser` is a super fast and tiny **HTML5** parser.
## Introduction
## Highlights
Currently, all the public parsers, like `htmlparser2`, `parser5`, etc,
could not be used for manipulate attributes. For example: the `htmlparser2`
has `startIndex` and `endIndex` for tags and texts, but no range information
about attribute name and values. This project is used for resolve this problem.
Just added ranges for tags, texts, and attribute name and values, and else,
with the information of attribute quote type, (without or with `'`/`"`).
- **[Fast](#benchmark)**: maybe the fastest one you can find on GitHub.
- **Tiny**: the fully packaged bundle size is less than `5kb`.
- **Cross platform**: works in the modern browsers and Node.js.
- **[HTML5 only](#warnings)**: any thing not in the specification will be ignored.
- **Accurate**: every token could be located in source file.

# var yarn
yarn add html5parser
```
## Installation
## Quick Start
1. Package manager
```ts
import * as html from 'html5parser';
```bash
npm i -S html5parser
const input = `
<!DOCTYPE html>
<html>
<body>
<h1 id="hello">Hello world</h1>
</body>
</html>
`;
# or var yarn
yarn add html5parser
```
const ast = html.parse(input);
2. CDN
html.walk(ast, {
```html
<script src="https://unpkg.com/html5parser@latest/dist/html5parser.umd.js"></script>
```
## Quick start
[![Edit html5parser - quick start](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/keen-wind-2mpwr?fontsize=14&hidenavigation=1&theme=dark)
```typescript jsx
import { parse, walk, SyntaxKind } from 'html5parser';
const ast = parse('<!DOCTYPE html><head><title>Hello html5parser!</title></head></html>');
walk(ast, {
enter: (node) => {
if (node.type === html.SyntaxKind.Tag) {
for (const attr of node.attributes) {
if (attr.value !== void 0) {
// This is used for present the ranges of attributes.
console.log(input.substring(attr.value.start, attr.value.end));
// you can get the value directly:
console.log(attr.value.value);
}
if (node.type === SyntaxKind.Tag && node.name === 'title' && Array.isArray(node.body)) {
const text = node.body[0];
if (text.type !== SyntaxKind.Text) {
return;
}
const div = document.createElement('div');
div.innerHTML = `The title of the input is <strong>${text.value}</strong>`;
document.body.appendChild(div);
}
},
});
```
// Should output:
// hello
## API Reference
### tokenize(input)
Low level API to parse string to tokens:
```typescript jsx
function tokenize(input: string): IToken[];
```
## API
- `IToken`
```ts
// Top level API, parse html to ast tree
export function parse(input: string, options?: ParseOptions): INode[];
```typescript jsx
interface IToken {
start: number;
end: number;
value: string;
type: TokenKind;
}
```
export interface ParseOptions {
// create tag's attributes map
// if true, will set ITag.attributeMap property
// as a `Record<string, IAttribute>`
// see {ITag#attributeMap} bellow
setAttributeMap: boolean;
}
- `TokenKind`
// Low level API, get tokens
export function tokenize(input: string): IToken[];
```typescript jsx
const enum TokenKind {
Literal,
OpenTag, // trim leading '<'
OpenTagEnd, // trim tailing '>', only could be '/' or ''
CloseTag, // trim leading '</' and tailing '>'
Whitespace, // the whitespace between attributes
AttrValueEq,
AttrValueNq,
AttrValueSq,
AttrValueDq,
}
```
// Utils API, walk the ast tree
export function walk(ast: INode[], options: IWalkOptions): void;
### parse(input)
// get safe html, remove danger tag/attributes with whitelist
export function safeHtml(
html: string,
options?: Partial<SafeHtmlOptions>,
): string;
Core API to parse string to AST:
// you can get default value of the options at ./src/safeHtml.ts
export interface SafeHtmlOptions {
allowedTags: string[];
allowedAttrs: string[];
tagAllowedAttrs: Record<string, string[]>;
allowedUrl: RegExp;
}
```typescript jsx
function parse(input: string, options?: ParseOptions): INode[];
```
## Abstract Syntax Tree Spec
- `ParseOptions`
1. `IBaseNode`: the base struct for all the nodes:
```typescript jsx
interface ParseOptions {
// create tag's attributes map
// if true, will set ITag.attributeMap property
// as a `Record<string, IAttribute>`
setAttributeMap: boolean;
}
```
```ts
export interface IBaseNode {
start: number; // the start position of the node (include)
end: number; // the end position of the node (exclude)
}
```
- `INode`
2. `IText`: The text node struct:
```typescript jsx
export type INode = IText | ITag;
```
```ts
export interface IText extends IBaseNode {
type: SyntaxKind.Text;
value: string; // text value
}
```
- `ITag`
3. `ITag`: The tag node struct
```typescript jsx
export interface ITag extends IBaseNode {
type: SyntaxKind.Tag;
// original open tag, <Div id="id">
open: IText;
// lower case tag name, div
name: string;
// original case tag name, Div
rawName: string;
attributes: IAttribute[];
// the attribute map, if `options.setAttributeMap` is `true`
// this will be a Record, key is the attribute name literal,
// value is the attribute self.
attributeMap: Record<string, IAttribute> | undefined;
body:
| Array<ITag | IText> // with close tag
| undefined // self closed
| null; // EOF before open tag end
// original close tag, </DIV >
close:
| IText // with close tag
| undefined // self closed
| null; // EOF before end or without close tag
}
```
```ts
export interface ITag extends IBaseNode {
type: SyntaxKind.Tag;
open: IText;
name: string;
attributes: IAttribute[];
// the attribute map, if `options.setAttributeMap` is `true`
// this will be a Record, key is the attribute name literal,
// value is the attribute self.
attributeMap: Record<string, IAttribute> | undefined;
body:
| Array<ITag | IText> // with close tag
| undefined // self closed
| null; // EOF before open tag end
close:
| IText // with close tag
| undefined // self closed
| null; // EOF before end or without close tag
}
```
- `IAttribute`
4. `IAttribute`: the attribute struct:
```typescript jsx
export interface IAttribute extends IBaseNode {
name: IText;
value: IAttributeValue | undefined;
}
```
```ts
export interface IAttribute extends IBaseNode {
name: IText; // the name of the attribute
value: IAttributeValue | void; // the value of the attribute
}
```
- `IAttributeValue`
5. `IAttributeValue`: the attribute value struct:
```typescript jsx
export interface IAttributeValue extends IBaseNode {
value: string;
quote: "'" | '"' | undefined;
}
```
```ts
// NOTE: the range start and end contains quotes.
export interface IAttributeValue extends IBaseNode {
value: string; // the value text, exclude leading and tailing `'` or `"`
quote: "'" | '"' | void; // the quote type
}
```
- `IText`
6. `INode`: the exposed nodes:
```typescript jsx
export interface IText extends IBaseNode {
type: SyntaxKind.Text;
value: string;
}
```
```ts
export type INode = ITag | IText;
```
- `IBaseNode`
```typescript jsx
export interface IBaseNode {
start: number;
end: number;
}
```
- `SyntaxKind`
```typescript jsx
export enum SyntaxKind {
Text = 'Text',
Tag = 'Tag',
}
```
### walk(ast, options)
Visit all the nodes of the AST with specified callbacks:
```typescript jsx
function walk(ast: INode[], options: WalkOptions): void;
```
- `IWalkOptions`
```typescript jsx
export interface IWalkOptions {
enter?(node: INode, parent: INode | void, index: number): void;
leave?(node: INode, parent: INode | void, index: number): void;
}
```
### safeHtml(input)
Parse input to AST and keep the tags and attributes by whitelists, and then
print it to a string.
```typescript jsx
function safeHtml(input: string, options?: Partial<SafeHtmlOptions>): string;
```
<a name="safehtmloptions"></a>
- `SafeHtmlOptions`
```typescript jsx
export interface SafeHtmlOptions {
allowedTags: string[];
allowedAttrs: string[];
tagAllowedAttrs: Record<string, string[]>;
allowedUrl: RegExp;
}
```
#### safeHtmlDefaultOptions
The default options of [`safeHtml`](#safehtmlinput), you can modify it, its
effect is global.
```typescript jsx
const safeHtmlDefaultOptions: SafeHtmlOptions;
```
