# `String.random(options = { ... })` _(ext/string/random)_
|
||
|
|
|
||
|
|
Returns generated random string, contained only of ascii cars `a-z` and `0-1`.
|
||
|
|
By default returns string of length `10`.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
const random = require("ext/string/random");
|
||
|
|
|
||
|
|
random(); // "upcfns0i4t"
|
||
|
|
random({ length: 3 }); // "5tw"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Supported options:
|
||
|
|
|
||
|
|
### `isUnique: false`
|
||
|
|
|
||
|
|
Ensures generated string is unique among ones already returned.
|
||
|
|
|
||
|
|
_Note: When not applying this setting, accidental generation of same string is still highly unlikely. Provided option is just to provide a mean to eliminate possibility of an edge case of duplicate string being returned_
|
||
|
|
|
||
|
|
### `length: 10`
|
||
|
|
|
||
|
|
Desired length of result string
|
||
|
|
|
||
|
|
### `charset: null`
|
||
|
|
|
||
|
|
Fixed list of possible characters
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
random({ charset: "abc" }); // "bacbccbbac"
|
||
|
|
```
