Typegoose Automatic Increment
Automaticly Increment properties
Basic Usage
Simple
(mongoose)
const schema = new mongoose.Schema({
somefield: Number
});
schema.plugin(AutoIncrementSimple, [{ field: 'somefield' }]);
const model = mongoose.model('SomeModel', schema);
const doc = await model.create({ somefield: 10 });
await doc.save(); // somefield will be 11
(typegoose)
@plugin(AutoIncrementSimple, [{ field: "someIncrementedField" }])
class SomeClass {
@prop() // does not need to be empty
public someIncrementedField: number;
}
const SomeModel = getModelForClass(SomeClass);
const doc = await SomeModel.create({ someIncrementedField: 10 });
await doc.save(); // someIncrementedField will be 11
For Identification
const schema = new mongoose.Schema({
_id: Number,
somefield: Number
});
schema.plugin(AutoIncrementID, {});
const model = mongoose.model('SomeModel', schema);
const doc = await model.create({ somefield: 10 }); // _id will be 1
(typegoose)
@plugin(AutoIncrementID, {})
class SomeClass {
@prop()
public _id: number;
@prop() // does not need to be empty
public someIncrementedField: number;
}
const SomeModel = getModelForClass(SomeClass);
const doc = await SomeModel.create({ someIncrementedField: 10 }); // _id will be 1
Motivation
I started @typegoose/auto-increment
because mongoose-auto-increment
and mongoose-auto-increment-reworked
are archived and didnt get any update for at least 2 years, and there were many issues about them in typegoose so i thought it will be easy to make an up-to-date automatic incrementing plugin
Requirements
- Node 12.22.0+
- TypeScript 4.4+ (older versions could work, but are not tested)
- mongoose 6.2+
Install
npm i -s @typegoose/auto-increment
You also need to install mongoose
, because this plugin is made for mongoose
Testing
npm run test
/ npm run test:watch

Documentation
AutoIncrementSimple - Options
The options can either be an object or an array of objects (single field / multiple fields)
Note: This function will only increment if the document is not new, this is to apply the default value
field
string
This option is always required to get which field to increment
incrementBy
number
default 1
This option is optional, default is to increment by 1
AutoIncrementID - Options
The options can only be one single object
This plugin variant uses a model and a collection to store tracking(/counter) infomation to keep track of the ID in case the latest one gets deleted
Note: the model used to keep track of the counter, will use the connection that the assigned schema uses Note: when the model is completly new, the first document will be "1", see here as on why
if the hook should be skipped, use AutoIncrementIDSkipSymbol
const doc = new Model();
doc[AutoIncrementIDSkipSymbol] = true;
await doc.save();
Note: AutoIncrementIDSkipSymbol
can also be set inside hooks, but hooks might be called before others
incrementBy
number
default 1
This option is optional, default is to increment by 1
field
string
This option is optional, defaults to _id
trackerCollection
string
Set the Collection the tracker should use to store tracking infomation
This option is optional, defaults to identitycounters
trackerModelName
string
Set the ModelName to use for the tracker model
This option is optional, defaults to identitycounter
startAt
number
default 0
Set the starting number of the counter (the first document will be this number)
Notes
- Please dont add comments with
+1
or something like that, use the Reactions npm run doc
generates all documentation for all files that can be used as modules (is used for github-pages)npm run doc:all
generates documentation even for internal modules
