## Run the examples

### Instructions

**Note**: All code examples are written in ECMAscript 6 (ES6). For guidelines on converting to CommonJS, see
[JavaScript ES6/CommonJS syntax](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/sdk-examples-javascript-syntax.html).

**Run a single action**

```bash
node ./actions/<fileName>
```

**Run a scenario**

Most scenarios can be run with the following command:
```bash
node ./scenarios/<fileName>
```

**Run with options**

Some actions and scenarios can be run with options from the command line:
```bash
node ./scenarios/<fileName> --option1 --option2
```
[util.parseArgs](https://nodejs.org/api/util.html#utilparseargsconfig) is used to configure
these options. For the specific options available to each script, see the `parseArgs` usage
for that file.
