AWSLambda

AWS Lambda Functions

Dev

Under root directory, run

``
npm ci
`

Make sure your editor support eslint and prettier (maybe you'll need to add extensions for them). VS Code (https://code.visualstudio.com/) is suggested here as the editor.

#### Configure Visual Studio Code

1. Install Eslint and Prettier extensions

2. Update settings to make use of the extensions, and let Prettier auto-format the code based on the eslint config file.
More specifically: In the top nav bar of VS Code, click Code -> Preferences -> Settings -> {} at the top right coner as shown below.

Update the settings as

`
{
// Editor
"explorer.confirmDelete": false,
"explorer.confirmDragAndDrop": false,
"window.openFilesInNewWindow": "on",
"window.zoomLevel": 0,
"editor.fontSize": 14,
"files.autoSave": "onFocusChange",
"editor.formatOnSave": true,
// Use eslint config as the rules for prettier
"javascript.format.enable": false, // disable default formatter
"prettier.eslintIntegration": true
}
`

Then restart the vs code editor, you should see Prettier automatically format your code, whenver you save your file.
!vscode auto formatting

Deploy using Serverless

$3

####Setup serverless module

First install serverless globally:

`
npm install -g serverless
`

####Setup AWS credentials
Edit ~/.aws/credentials and ~/.aws/config files under directory. For windows users this is C:\Users\USERNAME\.aws'

credentials file:

``
[aquaNow-PROD]
aws_access_key_id=...
aws_secret_access_key=...
`

config file - configure profile name and cloudformation stack region

`
[aquaNow-PROD]
region=us-east-1
`

When deploying the project, a stage variable is used to specify which environment (AWS Account) will the lambdas (as well as other infrastructures) be deployed to. Currently the available stage variables include: PROD, DEV.

Deploy the entire project:

`
sls deploy --stage PROD
`

Update a function - this is useful when you want to update and test a single lambda function:

`
sls deploy --stage PROD --function orderHistory
`

Create API Key for a user

`
const request = require("request");

const executeAPIUrl = 'https://execute.aquanow.io'; // Adjust your url accordingly

const options = {
method: 'POST',
url: ${executeAPIUrl}/apiKey,
headers:
{
'cache-control': 'no-cache',
'Content-Type': 'application/json'
},
body: {
userId: 'fuzionadmin', // required | username
customerId: 'aquanow', // optional
},
json: true
};

request(options, function (error, response, body) {
if (error) throw new Error(error);

console.log(body);
});

`

Run scripts in script folder

Make sure you have correct aws credentials configured on your terminal. You can check aws credentials using aws configure

`
npm run script scripts/addRfqExchange.js
