This plugin shares AWS.DynamoDB.DocumentClient() object, so you can easy use DynamoBD with fastify.
npm i fastify-dynamodb -S
Add it to you project with register and you are done!
You can access the DynamoDB DocumentClient via fastify.dynamo. The low-level client is also available via fastify.dynamoClient.
const fastify = require('fastify')()
fastify.register(require('fastify-dynamodb'), {
endpoint: 'http://localhost:8000',
region: AWS_REGION
})
fastify.listen(3000, err => {
if (err) throw err
console.log(`server listening on ${fastify.server.address().port}`)
})In your route file you can use the dynamodb client to perform queries: For further documentation on querying, see the DynamoDBDocumentClient docs.
const { GetCommand } = require("@aws-sdk/lib-dynamodb")
async function singleRoute(fastify, options) {
fastify.get(
'/users/:id',
async (request, reply) => {
let data
const { id } = request.params;
const params = {
TableName: TABLE_NAME,
Key: {
user_id: id
},
};
try {
data = await fastify.dynamo.send(new GetCommand(params));
} catch (e) {
reply.send(e)
}
return { data }
},
)
