Check this out: http://docs.mongodb.org/manual/tutorial/create-an-auto-incrementing-field/

ObjectId has 12 bytes and a total of 96 bits of information. If hexadecimal is used, each bit can provide 6 bits of information, so only 16 64-bits are needed. There are 62 letters + numbers in total, just find two punctuation marks :-)

You can use numbers to increase your ID
Mongodb officially provides a solution for self-increasing ID, please refer to

http://docs.mongodb.org/manual/tutorial/create-an-auto-incrementing-field/

The main principle is to create a new collection of counter counts in the database, record the maximum ID of each model, and then update the ID when saving. Use $inc in findAndModify to achieve increment. $inc is an atomic operation.

Create a new field to store the ID. When storing, take a screenshot.

Or use a customized Slug.

If it is an interface type, it will not be displayed directly in the browser address bar, so just use ObjectId.
