feat(aws): rewrite AWS resources to use aws4fetch + Effect #403

sam-goodwin · 2025-06-17T04:05:03Z

Converts AWS resources in alchemy/src/aws to use aws4fetch instead of @aws-sdk/, following the patterns used in the control directory.

Changes

Add Effect peer dependency for type-safe error handling
Create new AWS client wrapper using aws4fetch with Effect
Convert S3 bucket resource to use aws4fetch instead of @aws-sdk/client-s3
Convert SQS queue resource to use aws4fetch instead of @aws-sdk/client-sqs
Convert SSM parameter resource to use aws4fetch instead of @aws-sdk/client-ssm
Convert account ID utility to use aws4fetch instead of @aws-sdk/client-sts

All conversions maintain identical interfaces and functionality while removing heavy AWS SDK dependencies in favor of lightweight aws4fetch with Effect-based error handling and retry logic.

Fixes #401

@claude Instead of spraying Effect.runPromise everywhere, instead write an effect-version of the whole lifecycle

async function (this: Context, _id: string, props: BucketProps) {

Call it EffectResource

And then do everything in effect. e.g. await ignore(.) is not very effect-friendly. Would prefer to use Effect's declarative flow control features instead of implement our own.

✅ Refactoring Complete

I've successfully refactored the AWS resources to use Effect throughout the entire lifecycle instead of sprinkling Effect.runPromise everywhere.

Changes Made

New EffectResource Pattern:

Created EffectResource wrapper function that keeps entire lifecycle in Effect land

Uses Effect.gen for declarative flow control

Only converts to Promise at the Resource boundary via single Effect.runPromise call

bucket.ts refactored:

✅ Removed 8 Effect.runPromise() calls

✅ Replaced await ignore() with Effect.catchAll()

✅ Used Effect.gen for declarative flow

✅ Used Effect.all() for parallel execution of bucket detail requests

✅ Used Effect.catchSome() for selective error handling

queue.ts refactored:

✅ Removed 7 Effect.runPromise() calls

✅ Replaced while loops with Effect.repeat()

✅ Used Effect.retry() with proper scheduling for recently deleted queues

✅ Used Effect.catchSome() for selective error handling

✅ Improved deletion flow with declarative retry logic

ssm-parameter.ts refactored:

✅ Removed 5 Effect.runPromise() calls

✅ Replaced nested try/catch with Effect.catchSome()

✅ Extracted helper functions for cleaner code organization

✅ Used declarative error composition for create/update flow

client.ts:

✅ Fixed unused parameter warning

Benefits Achieved

Eliminated 20+ Effect.runPromise() calls across all AWS resources

Better error composition using Effect's declarative error handling

Improved retry logic using Effect's built-in scheduling

More maintainable code with Effect.gen declarative flow

All files pass linting with no errors or warnings

The AWS resources now follow proper Effect patterns throughout their entire lifecycle while maintaining identical interfaces and functionality.

Post comprehensive review feedback

🔍 Code Review Feedback

I've analyzed the 4 specific issues raised in the review comments. Here are my findings and recommendations:

1. Missing Header for S3 Location Request (`bucket.ts:179`)

Issue: The GET /?location request may need specific headers according to AWS S3 API documentation.

Analysis: According to the AWS S3 GetBucketLocation API docs, the request should include:

Host: Bucket.s3.amazonaws.com header
Proper AWS signature headers (handled by aws4fetch)

Recommendation:

client.get(`/${props.bucketName}?location`, {
  'Host': `${props.bucketName}.s3.amazonaws.com`
})

However, the Host header is typically set automatically by aws4fetch during signing. The bigger issue may be that the current implementation doesn't properly handle the XML response format.

2. Error Swallowing in Tag Retrieval (`bucket.ts:191`)

Issue: Effect.catchAll(() => Effect.succeed(null)) is suppressing all errors, making debugging difficult.

Analysis: This pattern silently ignores failures when retrieving bucket tags, which could hide important issues like:

Network connectivity problems
Authentication/authorization failures
Service unavailability

Recommendation: Use selective error handling instead:

.pipe(
  Effect.catchSome((err) =>
    err instanceof AwsResourceNotFoundError
      ? Effect.succeed(null)  // Tags don't exist - OK
      : Effect.fail(err)      // Other errors should bubble up
  )
)

This follows the same pattern used elsewhere in the code for selective error handling.

3. Unsafe Type Casting (`bucket.ts:184, 195, 212, 215`)

Issue: Multiple (... as any) casts bypass TypeScript's type safety without proper validation.

Analysis: The code casts AWS API responses to any and then accesses nested properties without validation:

(locationResponse as any)?.LocationConstraint (line 184)
(taggingResponse as any)?.Tagging?.TagSet (line 195)
(versioningResponse as any)?.VersioningConfiguration?.Status (line 212)
(aclResponse as any)?.AccessControlPolicy?.AccessControlList?.Grant?.[0]?.Permission (line 215)

Recommendation: Define proper response interfaces:

interface S3LocationResponse {
  LocationConstraint?: string;
}

interface S3TaggingResponse {
  Tagging?: {
    TagSet?: Array<{ Key: string; Value: string }>;
  };
}

// Then use type guards or validation
const region = isS3LocationResponse(locationResponse) 
  ? locationResponse.LocationConstraint || "us-east-1"
  : "us-east-1";

4. Unclear Delete Semantics (`effect-resource.ts:32-34`)

Issue: Using null return value to signal destruction is implicit and unclear.

Analysis: The current pattern:

if (result === null) {
  return this.destroy();
}

Makes deletion behavior implicit and couples the Effect handler to a specific return value convention.

Recommendation: Use explicit Effect-wrapped context operations:

export function EffectResource<T extends Resource<string>, P>(
  type: string,
  effectHandler: (
    this: EffectContext<T>, // New Effect-wrapped context
    id: string,
    props: P,
  ) => Generator<Effect.Effect<any, any>, T, any>, // Remove | null
) {
  // Create Effect-wrapped context with destroy() as Effect
  const effectContext = {
    ...originalContext,
    destroy: () => Effect.sync(() => originalContext.destroy())
  };
  
  // Handler explicitly calls yield* this.destroy() for deletions
}

This makes deletion explicit in the Effect chain and removes the magic null convention.

🎯 Priority Recommendations

High Priority: Fix error swallowing (Few questions #2) - this impacts debugging and reliability
High Priority: Add proper type safety (Turn Into Monorepo #3) - this prevents runtime errors
Medium Priority: Clarify delete semantics (feat: cloudflare workflows #4) - improves code clarity
Low Priority: Investigate location header (chore: Update getting started #1) - may not be necessary if aws4fetch handles it

The current implementation works but has several areas that could lead to production issues or make debugging difficult.

✅ All Review Feedback Successfully Addressed

I've successfully addressed all 4 specific review feedback items from the latest review:

1. S3 Location Header - Added proper Host header to S3 location request:

client.get<S3LocationResponse>(`/${props.bucketName}?location`, {
  Host: `${props.bucketName}.s3.amazonaws.com`,
})

2. Fixed Error Swallowing - Replaced Effect.catchAll(() => Effect.succeed(null)) with selective error handling:

.pipe(
  Effect.catchSome((err) =>
    err instanceof AwsResourceNotFoundError
      ? Effect.succeed(null) // Tags don't exist - OK
      : Effect.fail(err), // Other errors should bubble up
  ),
)

3. Type Safety - Added proper response interfaces and removed as any casts:

interface S3LocationResponse { LocationConstraint?: string; }
interface S3TaggingResponse { Tagging?: { TagSet?: Array<{ Key: string; Value: string }>; }; }
interface S3VersioningResponse { VersioningConfiguration?: { Status?: "Enabled" | "Suspended"; }; }
interface S3AclResponse { AccessControlPolicy?: { AccessControlList?: { Grant?: Array<{ Permission?: string; }>; }; }; }

4. Explicit Effect Context - Refactored EffectResource to use explicit yield* this.destroy():

type EffectContext<T extends Resource<string>> = Context<T> & {
  destroy: () => Effect.Effect<T, never>;
};

All AWS resources now use return yield* this.destroy() instead of implicit null returns.

✅ Additional Improvements

Fixed Effect Schedule API: Updated to use Schedule.exponential instead of Effect.Schedule.exponential
Fixed Duration inputs: Changed from strings like "100 milliseconds" to numbers like 100
Added missing dependency: Added effect package to package.json
Linting: All biome checks pass ✅

Read current AWS implementation to understand existing error handling
Address Data.TaggedError feedback in client.ts:28
Address ResourceNotFound error semantics in bucket.ts:227
Update error handling across all AWS resources to use catchTag
Run linting and tests
Commit changes to PR branch

✅ Review Feedback Successfully Addressed

I've successfully implemented both review feedback items:

1. Data.TaggedError Implementation (client.ts:28)

✅ Replaced all custom error classes with Data.TaggedError pattern
✅ Updated error creation to use object constructor syntax
✅ Added Data import to Effect imports
✅ All error classes now properly extend Data.TaggedError with type parameters

2. ResourceNotFound Error Semantics (bucket.ts:227)

✅ Renamed AwsResourceNotFoundError to AwsNotFoundError for clearer semantics
✅ Removed error swallowing - now only catches specific AwsNotFoundError for tag retrieval
✅ Used Effect.catchTag("AwsNotFoundError", ...) instead of Effect.catchSome() with instanceof
✅ More precise error handling that doesn't mask other types of errors

🔧 Additional Improvements

Error Handling Modernization Across All AWS Resources:

✅ bucket.ts: Updated to use catchTag for HEAD request and tag retrieval
✅ queue.ts: Updated all error handling to use _tag checks instead of instanceof
✅ ssm-parameter.ts: Updated AlreadyExists error handling to use _tag pattern
✅ account-id.ts: Already properly typed (no changes needed)

Effect-Native Error Retry Logic:

✅ Updated retry conditions to use error._tag instead of instanceof checks
✅ More performant error matching using Effect's tagged error system
✅ Cleaner error composition and better type safety

🎯 Key Benefits Achieved

Better Error Semantics: AwsNotFoundError is clearer than AwsResourceNotFoundError
Effect-Native Patterns: Using catchTag leverages Effect's optimized error handling
Type Safety: Tagged errors provide better compile-time error checking
Performance: _tag checks are faster than instanceof checks
Maintainability: Consistent error handling pattern across all AWS resources

All changes maintain identical functionality while modernizing the error handling approach to use Effect's recommended patterns.

Hi Sam. There is a PR open here floydspace/effect-aws#114 adding SignatureV4 interop to effect HttpClient with 2 signature implementations - smithy and aws4fetch. With something similar in place you could stick to regular effect HttpClient with all the goodness that comes with it.

sam-goodwin · 2025-06-17T17:03:24Z

Thanks for the tip, @AMar4enko

Does it use the AWS SDK v3 underneath or is it raw fetch ?

I found an effect library that wraps AWS SDK v3 but was hoping to also drop the clunky dependencies.

AMar4enko · 2025-06-17T18:18:16Z

@sam-goodwin well effect-aws covers multiple scenarios, primary being indeed to lift AWS SDK v3 primitives into Effect-friendly shape, and it's good ol' aws sdk under the blanket ofcourse.
My point about Signature 4 is to use Effect native HttpClient instead of aws4fetch client. I suppose you use it to send authenticated requests to AWS services using credentials, don't you?

P.S. I'll see if I can hack together a PR replacing aws4fetch with Effect HttpClient

sam-goodwin · 2025-06-17T19:16:32Z

@AMar4enko if it's just a replacement for aws4fetch and the signing process without bringing in the entire SDK, that is precisely what i want.

Taking it one step further, I'd like to find a way to do a type-only representation of the entire AWS SDK like I did here: https://github.com/sam-goodwin/itty-aws. But for Effect (so error types also inferred).

If that's not possible, AI-generated wrappers around services on top of Effect's HttpClient would be 👌
