Mongoose plugin for auto-generate better-read _id



### Installation

```bash

$ yarn add mongoose-better-id

```



### Example

```js

const betterId = require('mongoose-better-id');



schema.plugin(betterId, {

  connection,

  field: '_id',

  prefix: 'person',

  suffix: {

    start: 0,

    step: 1,

    max: 99,

  },

  timestamp: {

    enable: true,

    format: 'yyMMddhhmmssS'

  }

});

```



### Options

* connection {`MongooseConnection`} `required` The db to save id counter;

* field {`string`} `default: '_id'` The field to generate id;

* prefix {`string`} `default: ''` The prefix string of the id;

* suffix {`object`} The suffix of the id, it's a auto increment number;

  - start {`number`} `default: 0` The start number of the suffix;

  - step {`number`} `default: 1` The step of the suffix to increment every time to generate;

  - max {`number`} `default: 999` The max value of the suffix, when the suffix reached the value it will reset to start value;

* timestamp {`object`} The timestamp string between prefix and suffix;

  - enable {`boolean`} `default: true` When set `true`, a string of the certain `format` of current time will add between prefix and suffix;

  - format {`string`} `default: 'yyMMddhhmm'` The format the current time will be formatted.



An id string will look like `1610211329190` with default options;



### Caution

The suffix is cycling between start and max value, so if you generate more than the max mount of the suffix

in the same time (eg. in 1 minute the default timestamp between prefix and suffix will not change),

it will cause an unique error on id field.

So you must:

1. Change the timestamp format to contain the `S`(like `yyMMddhhmmssS`), which means millisecond, to prevent the trouble as for as possible.

2. Add a pre save middleware after use the plugin to add your custom random string after the id.

3. BTW, for general business, 1000 times of data create in 1 minutes is really enough :)
