## Introduction

Sharkitek is a Javascript / TypeScript library designed to ease development of client-side models.
|

Sharkitek is a lightweight Javascript / TypeScript library designed to ease development of models.
|
||||
|
||||
With Sharkitek, you define the architecture of your models by specifying their properties and their types.
|
||||
Then, you can use the defined methods like `serialize`, `deserialize`, `patch` or `serializeDiff`.

## Examples

## Quick start
|
||||
|
||||
### Simple model definition
|
||||
**Note**: by convention, we define our models in a `model` static variable in the model's class. It is a good way to keep your model declaration near the actual class, and its usage will be more natural.
|
||||
|
||||
### Model definition

||||

### Model functions
|
||||
|
||||
#### Serialization
|
||||
|
||||
```typescript
|
||||
const instance = new Person();
|
||||
instance.id = 1;
|
||||
instance.createdAt = new Date();
|
||||
instance.name = "John Doe";

instance.email = "john@doe.test";
|
||||
instance.active = true;
|
||||
const serialized = Person.model.model(instance).serialize();
|
||||
console.log(serialized); // { id: 1, createdAt: "YYYY-MM-DDTHH:mm:ss.sssZ", name: "John Doe", email: "john@doe.test", active: true }
|
||||
```
|
||||
|
||||
#### Deserialization
|
||||
|
||||
```typescript
|
||||
const instance = Person.model.parse({
|
||||
id: 1,
|
||||
createdAt: "2011-10-05T14:48:00.000Z",
|
||||
name: "John Doe",
|
||||
email: "john@doe.test",
|
||||
active: true,
|
||||
});
|
||||
console.log(instance instanceof Person); // true
|
||||
console.log(instance.createdAt instanceof Date); // true
|
||||
```
|
||||
|
||||
#### Patch
|
||||
|
||||
```typescript
|
||||
const instance = Person.model.parse({
|
||||
id: 1,
|
||||
createdAt: "2011-10-05T14:48:00.000Z",

|
||||
email: "john@doe.test",
|
||||
active: true,
|
||||
});
|
||||
|
||||
instance.name = "Johnny";
|
||||
|
||||
// Patch serialized only changed properties and the identifier.
|
||||
console.log(Person.model.model(instance).patch()); // { id: 1, name: "Johnny" }
|
||||
// If you run it one more time, already patched properties will not be included again.
|
||||
console.log(Person.model.model(instance).patch()); // { id: 1 }
|
||||
```
|
||||
|
||||
#### Identifier
|
||||
|
||||
```typescript
|
||||
const instance = new CompositeKeys();
|
||||
instance.id1 = 5;
|
||||
instance.id2 = "foo";
|
||||
const instanceIdentifier = CompositeKeys.model.model(instance).getIdentifier();
