initialize-local-dynamo

Seeds a local docker instance with data and packages it into a docker container

Start Dynamo

Pulls an empty copy of a local DynamoDb docker container and starts it.

index.StartDynamo({
    InitializationType: index.InitializationType.SharedDb),
    port: 8000
})

SeedDynamo

Given a directory containing table definitions this creates all tables and seeds the data.

index.SeedDynamo(directoryPath);

Each file should contain the definition for a single table and export two variables:

• table_params - a single object containing the table definition
• updates - an array of data points for the table

The format for table_params and updates objects are the same as for performing actions via the NodeJS AWS SDK. An example of this can be found in the integration tests.

SaveChanges

Commits the seeded data into a docker image which can be persisted in a docker repository.

var repository = "chagedorn/initialize-local-dynamo";
var tag = "test";

index.SaveChanges(repository, tag)

Example

Putting it all together these can be chained together:

var seeding = require('initialize-local-dynamo');
var tableDirectory = __dirname + '/tables';
var repository = "chagedorn/initialize-local-dynamo";
var tag = "test";

seeding.StartDynamo({
      InitializationType: index.InitializationType.SharedDb),
      port: 8000
  })
  .then(function() {
      return seeding.SeedDynamo(tableDirectory);
  })
  .then(function() {
      return seeding.SaveChanges(repository, tag);
  })
  .catch(function(err) {
      console.log(err);
      throw Error(err);
  });
