## Prerequisite
21
+
22
+
### Typescript Metadata
23
+
24
+
#### Reflection API
25
+
26
+
> ⚠ The reflect-metadata polyfill should be imported only once in your entire application because the Reflect object is
27
+
mean to be a global singleton.
28
+
29
+
Install the reflect-metadata polyfill.
30
+
31
+
```
32
+
npm install reflect-metadata --save
33
+
```
34
+
35
+
The type definitions for reflect-metadata are included in the npm package.
36
+
You need to add the following reference to the types field in your [tsconfig.json](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#types-typeroots-and-types):
37
+
38
+
```
39
+
"types": ["reflect-metadata"]
40
+
```
41
+
42
+
Finally, import reflect-metadata in some entry file in your application.
43
+
44
+
```
45
+
import "reflect-metadata"
46
+
```

+

#### Decorators
49
+
50
+
51
+
We need to enable the two experimental features to work with decorators, add this to your tsconfig.json:
52
+
53
+
```
54
+
"experimentalDecorators": true
55
+
"emitDecoratorMetadata": true
56
+
```

## First Sample

+
64
+
When all the setup work is done, define your first model and create a dynamo store to execute actions on the dynamoDB.

```typescript

@Model()

# Decorators
63
102
Decorators are used to add some metadata to our model classes, relevant to our javascript-to-dynamo mapper.
64
103
65
-
This is an experimental feature and requires to set the following typescript compiler options:
66
-
67
-
- "experimentalDecorators": true
68
-
- "emitDecoratorMetadata": true
69
-
70
104
Additionally we rely on the reflect-metadata (https://www.npmjs.com/package/reflect-metadata) library for reflection api.

To get started with decorators just add a [@Model()](https://shiftcode.github.io/dynamo-easy/modules/_decorator_impl_model_model_decorator_.html) Decorator to any typescript class.
