# dynamodb | ||
|
||
## Prerequisites | ||
|
||
- [winglang](https://winglang.io). | ||
|
||
## Installation | ||
|
||
```sh | ||
npm i @winglibs/dynamodb | ||
``` | ||
|
||
## Usage | ||
|
||
```js | ||
bring dynamodb; | ||
|
||
let table = new dynamodb.Table( | ||
attributes: [ | ||
{ | ||
name: "id", | ||
type: "S", | ||
}, | ||
], | ||
hashKey: "id", | ||
); | ||
|
||
// Streams. | ||
table.setStreamConsumer(inflight (record) => { | ||
log("record processed = {Json.stringify(record)}"); | ||
}); | ||
|
||
// Put and query. | ||
test "put and query" { | ||
table.put( | ||
item: { | ||
id: "1", | ||
body: "hello", | ||
}, | ||
); | ||
let response = table.query( | ||
keyConditionExpression: "id = :id", | ||
expressionAttributeValues: {":id": "1"}, | ||
); | ||
assert(response.count == 1); | ||
assert(response.items.at(0).get("id").asStr() == "1"); | ||
assert(response.items.at(0).get("body").asStr() == "hello"); | ||
} | ||
``` | ||
|
||
In case you want to instantiate your own DynamoDB SDK, you can get the connection details like this: | ||
|
||
```wing | ||
let connection = table.connection(); | ||
connection.endpoint; | ||
connection.tableName; | ||
``` | ||
