@rcoundon They should still be available as variables using ${} syntax.
They can be referenced inside the configuration using the likes of
stage: '${opt:stage, self:provider.stage}',But what I'd like to do is to reference them outside of the configuration e.g.
import type { AWS } from '@serverless/typescript';
console.log('${opt:stage, self:provider.stage}');
const serverlessConfiguration: AWS = {
...
provider: {
name: 'aws',
stage: 'dev',
stackTags: {
stage: '${opt:stage, self:provider.stage}',
}
}const serverless = require('serverless'); // Haven't worked out why I can't use import here yet
const sls = new serverless();
console.log(sls.service.provider.stage); // prints 'dev'So, looking through source code of serverless led me to the processedInput variable.
Doing this
const serverless = require('serverless');
const sls = new serverless();
sls.init();
console.log(JSON.stringify(sls.processedInput, null, 2));Produces
{
"commands": [
"offline",
"start"
],
"options": {
"stage": "production"
}
}processedInput isn't marked as private so I guess this is 'safe'...
Hey! Is there a way to keep deletionPolicy on an s3 bucket and dynamodb table and use the same buckets / s3 from old deployments on new stacks?
I want to use the same serverless.yml to deploy new stacks and redeploy stack using the previously retained s3 buckets / dynamodb tables.
I've set up the:
DeletionPolicy: Retain
but currently getting
An error occurred: xxxx - xx-xx-xx-xx already exists.
on redeployments

@rcoundon Thanks ross. It's working now . But I'm able to do a post request using a curl command. But when I'm testing the API with fetch I'm getting cors error(CORS Missing Allow origin). But I haven't enabled cors while deploying in Aws Api gateway and in aws lamba also?
Hi - you can specify cors on the http event:
events:
- http:
path: somepath
method: post
cors: trueBut you also need to return the necessary CORS headers from your lambda function.
For example, you could define a function to add the necessary headers to your returned objects something like
export function addCorsHeaders(response: APIGatewayProxyResult): APIGatewayProxyResult {
if (!response.headers) {
response.headers = {};
}
response.headers['Access-Control-Allow-Headers'] = 'Content-Type';
response.headers['Access-Control-Allow-Origin'] = '*';
response.headers['Access-Control-Allow-Methods'] = 'OPTIONS,POST,GET,PATCH,PUT,DELETE';
return response;
}Then you'd use it like:
const response = {
statusCode: 200,
body: JSON.stringify({
message: 'some data',
}),
};
return addCorsHeaders(response);Ive been looking into ways to bundle a serverless node application. I see serverless-webpack has the option for
includeModulesbut is there a reason that you wouldn't just want webpack to bundle/treeshake everything for you and just output a single file?
includeModules just gives you some options around including/excluding certain packages. For example, you might use something that is OS specific like sharp for local testing but not want this bundled in the package, so you can then use includeModules/forceExclude with sharp. Also, if you wanted to be specific about what to include you can use forceInclude, maybe you might want to do that with aws-sdk rather than use the version that lambda containers automatically include
Hello, can someone please advise if the following makes sense?
functions:
myCloudWatch:
handler: myCloudWatch.handler
events:
- cloudwatchEvent:
event:
arn: "arn:aws:events:us-east-1:123456789012:rule/MyScheduledRule"
source:
- 'aws.events'
detail-type:
- 'Scheduled Event'Generally I want to grant the λ function with a permission to be invoked by some scheduled rules, which are dynamic and therefore cannot be defined in the configuration yaml.
Thanks
