yarn add @fntools/passwordIs a simple JS plugin for adding strength meter to password input. This plugin checks password input to meet the following requirements:
- Password has at least one lowercase alfabetic character.
- Password has at least one uppercase alfabetic character.
- Password has at least one numeric character.
- Password length has to be greater than 8 characters.
You can find a demo here. It's usage is straightforward:
HTML
<input id="psw-input" type="password">
<div id="pswmeter"></div>
<div id="pswmeter-message"></div>Add an ID for password input, the container where you want to show the pswmeter and the one that will show your messages (optional).
JS
// Run pswmeter with options
const myPassMeter = passwordStrengthMeter({
containerElement: '#pswmeter',
passwordInput: '#psw-input',
showMessage: true,
messageContainer: '#pswmeter-message'
});The first two options, containerElement and passwordInput, are required. You must indicate the containers using ID selectors only. Optionally, you can set showMessage to true if you want to show messages to the user. If you do so, you must add messageContainer to indicate the container using ID selector only.
Options
Customize the pswmeter by adding more properties inside the function's arguments. These are the available properties you can use:
| Option | Default value | Value type | Required | Explanation |
|---|---|---|---|---|
| containerElement | - | String | Yes | ID selector. For example: '#pswmeter' |
| passwordInput | - | String | Yes | ID selector. For example: '#psw-input' |
| height | 4 | Number | No | - |
| borderRadius | 2 | Number | No | - |
| pswMinLength | 8 | Number | No | - |
| colorScore1 | #ff7700 | String | No | Hex, RGB or named color values. For example: '#000', 'rgb(0,0,0)' or 'black' |
| colorScore2 | #ffff00 | String | No | Hex, RGB or named color values. For example: '#000', 'rgb(0,0,0)' or 'black' |
| colorScore3 | #aeff00 | String | No | Hex, RGB or named color values. For example: '#000', 'rgb(0,0,0)' or 'black' |
| colorScore4 | #00ff00 | String | No | Hex, RGB or named color values. For example: '#000', 'rgb(0,0,0)' or 'black' |
| showMessage | false | Boolean | No | By default this functionality is disabled, if you want to show messages you have to set this property to true |
| messageContainer | - | String | No | If you set showMessage to true you must indicate the ID selector for the container that will show messages. |
| messagesList | 'No data', 'Too simple', 'Simple', 'Thats OK', 'Great password!' | Array | No | The first 5 items inside this array will override the default values in order. The first item is shown when the password's score is equal to 0, the second item is shown when the password's score is equal to 1, and so on. |
Events
Custom events are dispatched from containerElement ready to be listened. These are the available events you can use:
| Event | Usage | Explanation |
|---|---|---|
| onScore0 | myPassMeter.containerElement.addEventListener('onScore0', function() { ... }) | This event is fired when the score is equal to 0. |
| onScore1 | myPassMeter.containerElement.addEventListener('onScore1', function() { ... }) | This event is fired when the score is equal to 1. |
| onScore2 | myPassMeter.containerElement.addEventListener('onScore2', function() { ... }) | This event is fired when the score is equal to 2. |
| onScore3 | myPassMeter.containerElement.addEventListener('onScore3', function() { ... }) | This event is fired when the score is equal to 3. |
| onScore4 | myPassMeter.containerElement.addEventListener('onScore4', function() { ... }) | This event is fired when the score is equal to 4. |
Methods
For now there is only one method available:
| Method | Usage | Returned possible values | Explanation |
|---|---|---|---|
| getScore | myPassMeter.getScore() | 0, 1, 2, 3 or 4 | When called, this method returns a Number with the current score of the selected password field. |
