Mongoose plugin for auto-generate better-read _id
$ yarn add mongoose-better-id
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'
}
});
- 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;
- start {
- timestamp {
object
} The timestamp string between prefix and suffix;- enable {
boolean
}default: true
When settrue
, a string of the certainformat
of current time will add between prefix and suffix; - format {
string
}default: 'yyMMddhhmm'
The format the current time will be formatted.
- enable {
An id string will look like 1610211329190
with default options;
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:
- Change the timestamp format to contain the
S
(likeyyMMddhhmmssS
), which means millisecond, to prevent the trouble as for as possible. - Add a pre save middleware after use the plugin to add your custom random string after the id.
- BTW, for general business, 1000 times of data create in 1 minutes is really enough :)
