Shows how to use the AWS SDK for JavaScript (v3) to work with Amazon DynamoDB.
DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability.
- Running this code might result in charges to your AWS account. For more details, see AWS Pricing and Free Tier.
- Running the tests might result in charges to your AWS account.
- We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
- This code is not tested in every AWS Region. For more information, see AWS Regional Services.
For prerequisites, see the README in the javascriptv3
folder.
- Hello DynamoDB (
ListTables
)
Code examples that show you how to perform the essential operations within a service.
Code excerpts that show you how to call individual service functions.
- BatchExecuteStatement
- BatchGetItem
- BatchWriteItem
- CreateTable
- DeleteItem
- DeleteTable
- DescribeTable
- ExecuteStatement
- GetItem
- ListTables
- PutItem
- Query
- Scan
- UpdateItem
Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.
Note: All code examples are written in ECMAscript 6 (ES6). For guidelines on converting to CommonJS, see JavaScript ES6/CommonJS syntax.
Run a single action
node ./actions/<fileName>
Run a scenario
Most scenarios can be run with the following command:
node ./scenarios/<fileName>
Run with options
Some actions and scenarios can be run with options from the command line:
node ./scenarios/<fileName> --option1 --option2
util.parseArgs is used to configure
these options. For the specific options available to each script, see the parseArgs
usage
for that file.
This example shows you how to get started using DynamoDB.
node ./hello.js
This example shows you how to do the following:
- Create a table that can hold movie data.
- Put, get, and update a single movie in the table.
- Write movie data to the table from a sample JSON file.
- Query for movies that were released in a given year.
- Scan for movies that were released in a range of years.
- Delete a movie from the table, then delete the table.
This example shows you how to do the following:
- Get a batch of items by running multiple SELECT statements.
- Add a batch of items by running multiple INSERT statements.
- Update a batch of items by running multiple UPDATE statements.
- Delete a batch of items by running multiple DELETE statements.
This example shows you how to do the following:
- Get an item by running a SELECT statement.
- Add an item by running an INSERT statement.
- Update an item by running an UPDATE statement.
- Delete an item by running a DELETE statement.
