Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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

Versioning

Major.Minor.Fix (or how npm expresses it Major.Minor.Patch)
(This Project should comply with Semver)

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
