Examples

TaskApp

TaskApp is a simple three Entity service that tracks Organizations, Employees, and Tasks.

Setup

The following examples use models and code within the ElectroDB repository for examples: electrodb. Follow the steps below to get setup or follow along.

Install ElectroCLI Globally

Install electrocli via npm globally. Note: This may require sudo or administrator privileges.

$> npm install electrocli --global

Clone/Download Examples

Clone the electrodb repository and then navigate to the the TaskApp example.

$> git clone https://github.com/tywalch/electrodb.git
$> cd electrodb/examples/taskapp

Configure your DynamoDB Target

It is recommended that you use the dynamodb-local docker image.

$> docker pull amazon/dynamodb-local
$> docker run -p 8000:8000 amazon/dynamodb-local

More information on how to setup and configure that here.

If you want to use your own DynamoDB instance in AWS (be careful with incurring fees) you can modify the client.js file located in the electrodb directory from above: electrodb/examples/taskapp/lib/client.js.

Load the database

Records can be loaded into the example table by executing the file electrodb/examples/taskapp/bin/load.js. You will be prompted to confirm loading by typing y.

$> node electrodb/examples/taskapp/bin/load.js
   Your configuration is pointed to a local instance of dynamodb. This operation will create a table named 'electro' and then load 500 Employees and 600 Tasks records. Are you sure you want to proceed? y/N
$> y

Add the "Taskr" Service to electro cli

Use the add command to add the taskr.js within the electrodb/examples/src directory.

$> electro add electrodb/examples/src/taskr.js

Query TaskApp

Run queries against your models directly from the command line.

$> electro query taskapp

Options:
  -r, --raw                  Return raw field response.
  -p, --params               Return DocumentClient params as results instead of querying the table.
  -t, --table <table>        Override table defined on Instance.
  -l, --limit <number>       Limit the number of results returned.
  -f, --filter <expression>  Supply a filter expression "<attribute>, <operation>, [value1] [value2]". Use double commas to escape a comma. Available attributes include employee, firstName, lastName, office, title, team, salary, manager, dateHired, birthday. (default: [])
  -d, --delete               Delete items returned from query.
  -h, --help                 display help for command

| Access Pattern | Command | | -------------: | ------- | | employee | [options] <employee> | | coworkers | [options] <office> [team] [title] [employee] | | teams | [options] <team> [dateHired] [title] | | employeelookup | [options] <employee> | | roles | [options] <title> [salary] | | directreports | [options] <manager> [team] [office] | | task | [options] <task> [project] [employee] | | project | [options] <project> [employee] [status] | | assigned | [options] <employee> [project] [status] | | statuses | [options] <status> [project] [employee] | | locations | [options] <country> <state> [city] [zip] [office] | | office | [options] <office> | | workplaces | [options] <office> [team] [title] [employee] | | assignments | [options] <employee> |

Serve CRUD HTTP Server for TaskApp

Stand up an HTTP Server based all of your models.

$> electro serve 8080

Options:
  -v, --view-only  Serve with only get/query operations as endpoints. (default: false)
  -h, --help       display help for command

Use the --view-only flag to stand up an http server without exposing any put/create/update/patch/delete operations.
