**Image Resize service**
---
Services:
--
- Lambda function
- API Gateway
This service requires an S3 Bucket as a source of images, set as Static Hosting, with the following
bucket policy:
-
```
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "AddPerm",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::BUCKET_NAME/*"
}
]
}
```
redirect rule:
-
```
404
https
API_GATEWAY_HOSTNAME
prod/resize?key=
307
```
ENV variables for BUCKET_NAME and URL are currently saved in the `function-template.yaml`
---
The image is requested in the folder on S3 that contains the resized copy like:
`path-to-image/s200x100/image.[jpg|webp]`
The original image must be in the parent folder like:
`path-to-image/image.jpg`
--
The 'resize' folder can have the following pattern:
- **s**200x100 (resize and crop with provided width and height)
- **w**200 (resize to provided width, keep ratio)
- **h**200 (resize to provided height, keep ratio)
--
Provess:
The file is requested to S3, when that size is not available the request gets redirected to the API gateway which fires the lambda function associated to perform the resize/crop/format on the original image.
*If a WEBP format is requested, the file will be generated always from the original JPG version and saved for further requests.*
Then the new file is saved in the correct folder into the S3 bucket itself and returned to the user.
