 1 | # Lambda-Contact
 2 | 
 3 | A simple aws-lambda function that allows you to have a contact form on your static website. (hosted on S3/Cloudfront) 
 4 | Currently, emails are sent via SES.
 5 | 
 6 | I made this aws-lambda function in August 2015 for a startup I joined and in 2017 I modified it to use serverless.
 7 | 
 8 | # Instructions
 9 | 
10 | 1. Install [serverless](https://serverless.com/)
11 | 2. Run `npm install`
12 | 3. Change the config.json file to match your 'from' to 'to'.
13 | 4. Run `serverless deploy`
14 | 5. Copy the URL from the output of the previous command and use it in your contact form.
15 | 
16 | ## Exmaple Form
17 | ```
18 | <form method="post" action="https://API_GATEWAY/contact">
19 |     <input name="name" required="true" placeholder="Name" type="text" id="name">
20 |     <input name="affiliation" placeholder="Affiliation" type="text">
21 |     <input name="email" placeholder="E-mail Address" type="email" required="true">
22 |     <textarea name="message" required="true" placeholder="Your message" maxlength="999"></textarea>
23 |     <button type="submit">Send</button>
24 | </form>
25 | ```
