mongoose-better-id

Mongoose plugin for auto-generate better-read _id

Installation

$ yarn add mongoose-better-id

Example

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 :)
