Logon on to the AWS Management console and select API Gateway and follow these steps.Ĭlick “Getting started”.Click “Create API”.Select check box “Import from Swagger”Paste following swagger template and then click “Import” Logon on to the AWS Management console and select IAM and follow these steps to set required permissions.Ĭlick on Roles and select mywebsite_lambda_role.Under Inline Polices select Create Role Policy.Select Custom Policy and enter mywebsite-contact-us-table as Policy name.Copy and paste the following policy. The Lambda function needs permissions to store data in the DynamoDB table mywebsite-contact-us. Set mywebsite_lambda_role as Role Name and Click Allow. Logon on AWS Management console and select Lambda and follow below steps.Ĭlick Create a Lambda function.Select Blank function.Skip Configure Triggers and click Next.In Configure function, set mywebsite-contact-us as Name and select Nodejs 8.10 as Runtime.Copy below function to Lambda function code.ħ. Once the table is ready, lets write a Lambda function in Node.js to store contact-us form data into this table. Note: Table creation may take few minutes. Logon on AWS Management console and select DynamoDB and follow these steps.Ĭlick Create table.Enter mywebsite-contact-us as Table name.Enter email as Partition key.Leave the rest of the settings as it is and click Create.
And finally we need an API endpoint to call the Lambda function from the website for that we will use Amazon API Gateway. Then we need an Amazon Lambda function to process the POST requests of the contact-us form. First we need a data store to keep our contact-us form data, and for that we will use Amazon DynamoDB (NoSQL Database). Lets create a contact-us api for a website. The best thing about these two services is, their Free Tier quota is quite high so you won’t have to pay anything until your website gets very popular. Amazon API Gateway gives us the ability to create any number of arbitrary APIs using Amazon Lambda as the backend.
When hosting the website using serverless technologies such as Amazon S3, APIs are essential for powering the dynamic sections of the website. In the previous post, we have discussed how to setup a static website using S3.Įvery website has at least one dynamic section like contact us, email subscription or a feedback form. This is Part-2 of a multi-part blog post of how you can run a fast dynamic website in a completely serverless manner using managed services provided by AWS.
