# example
|
||
|
||
``` js
|
||
var ent = require('ent');
|
||
console.log(ent.encode('<span>©moo</span>'))
|
||
console.log(ent.decode('π & ρ'));
|
||
```
|
||
|
||
```
|
||
<span>©moo</span>
|
||
π & ρ
|
||
```
|
||
|
||
|
||
|
||
# methods
|
||
|
||
``` js
|
||
var ent = require('ent');
|
||
var encode = require('ent/encode');
|
||
var decode = require('ent/decode');
|
||
```
|
||
|
||
## encode(str, opts={})
|
||
|
||
Escape unsafe characters in `str` with html entities.
|
||
|
||
By default, entities are encoded with numeric decimal codes.
|
||
|
||
If `opts.numeric` is false or `opts.named` is true, encoding will used named
|
||
codes like `π`.
|
||
|
||
If `opts.special` is set to an Object, the key names will be forced
|
||
to be encoded (defaults to forcing: `<>'"&`). For example:
|
||
|
||
``` js
|
||
console.log(encode('hello', { special: { l: true } }));
|
||
```
|
||
|
||
```
|
||
hello
|
||
```
|
||
|
||
## decode(str)
|
||
|
||
Convert html entities in `str` back to raw text.
