Architect plugin for Local DynamoDB Docker

This is a plugin for a local DynamoDB instance using Docker.

When you are using Architect's sandbox mode, the plugin starts a Docker container running the amazon/dynamodb-local image.

If you have defined a @tables-streams section in your app.arc file, the respective streams will be enabled and their configured lambdas automatically triggered.

Prerequisites

• Docker installed and running on your system.
• Node.js (if this project is built as a Node.js tool).

Usage

1. Install this package using npm:

   npm install -D @nasa-gcn/architect-plugin-dynamodb-local

2. In your .env add the following:

   ARC_TABLES_PORT=8000
   ARC_DB_EXTERNAL=true

3. Add the following to your project's app.arc configuration file:

   @plugins
   nasa-gcn/architect-plugin-dynamodb-local

4. Seeding the database (optional):

   @dynamodb-local
   seedFile your-seed-file.json

If you want to utilize the @tables-streams, include a json formatted seedFile. The database will be seeded automatically during initialization. This will happen BEFORE Architect's built-in seeding step. By default, Architect will look for a file named sandbox-seed.json or sandbox-seed.js to seed the database. If you use this feature name the file differently, otherwise this plugin will skip the file seeding. To easily switch from using the built-in seed function, you can simply rename your existing sandbox-seed.[js|json] file and pass that as an argument to the plugin.

Seed File Format

The seedFile should be a JSON file where the keys are the table names and the values are the list of items to be added. Example:

{
  "table1": [
    {
      "someProperty":"some value",
      ...
    },
    {
      ...
    }
  ],
  "table2": [
    ...
  ]
}
