Installation

Global Installation (Recommended)

pnpm link --global

Or in your project:

pnpm add -D electro-viewer

Configuration

Create an electro-viewer-config.ts file in your project root:

export const config = {
  // AWS profile name from ~/.aws/credentials or ~/.aws/config
  profile: "your-aws-profile",

  // AWS region (optional - uses profile's default if not specified)
  region: "us-east-1",

  // Paths or glob patterns to your ElectroDB entity files
  // Relative paths from your project root
  // Examples:
  //   ["./entities.ts"] - Single file
  //   ["./packages/*/entities.ts"] - Glob pattern
  //   ["./entities.ts", "./custom/*.ts"] - Mix of direct paths and globs
  entityConfigPaths: ["./path/to/your/entities.ts"],

  // Optional: Path to tsconfig.json (defaults to "./tsconfig.json")
  tsconfigPath: "./tsconfig.json",

  // Optional: Environment variables needed by your entities file
  env: {
    IS_PERMISSIONED_ENV: "false",
    NODE_ENV: "development",
  },
} as const;

export type ElectroViewerConfig = typeof config;

Option	Type	Required	Default	Description
profile	string	Yes	-	AWS profile name
region	string	No	Profile default	AWS region
entityConfigPaths	string[]	Yes	-	Paths or glob patterns to entity files
tsconfigPath	string	No	"./tsconfig.json"	Path to tsconfig.json
env	Record<string, string>	No	{}	Environment variables

Usage

SST

If you're using SST, you can add a custom commmand to the multiplexer to automatically start Electro Viewer when you run sst start:

new sst.x.DevCommand("ElectroViewer", {
  link: [myTable],
  dev: {
    autostart: true,
    command: "pnpm electro-viewer",
  },
});

How It Works

Electro Viewer reads your ElectroDB entities configuration files to understand the PK/SK structure of your entities. When running, we'll use the AWS SDK along with the AWS CLI to query DynamoDB to make it easier to query entities.

Make sure your AWS profile has permissions to:

• dynamodb:Query
• dynamodb:GetItem
• Access to the tables you want to query
