Greptile Summary

Created a centralized @sim/tsconfig package with four configuration presets (base, nextjs, library, library-build) and migrated all apps and packages to extend from these shared configs, eliminating ~200 lines of duplicate TypeScript configuration. Resolved type errors in the testing package by strategically relaxing types to use any with proper eslint directives, allowing the testing utilities to accept data shapes from any app without type conflicts. Updated all test files in apps/sim to work with the new testing package types.

Key Changes:

• Created @sim/tsconfig package with reusable TypeScript configurations
• Migrated 8 tsconfig.json files to extend from shared configs (apps/sim, apps/docs, 6 packages)
• Fixed testing package type errors by using any types for flexibility across different app types
• Updated Docker builds to include new tsconfig package and fixed isolated-vm path for Bun
• Moved misplaced dependencies from root to apps/sim package.json
• Updated User-Agent strings from "SimStudio" to "Sim" across 11 files for branding consistency

Confidence Score: 5/5

• This PR is safe to merge with no concerns
• Well-architected monorepo improvement that centralizes TypeScript configuration following best practices. The testing package type changes are intentional and properly documented - using any with eslint directives is the correct approach for a shared testing library that needs to work across different app types. All changes are consistent, backward-compatible, and the Docker updates properly account for Bun's module structure.
• No files require special attention

Important Files Changed

Filename	Overview
packages/tsconfig/package.json	added new shared tsconfig package with proper exports for base, nextjs, library, and library-build configurations
packages/tsconfig/base.json	created base TypeScript configuration with ES2022 target, strict mode, and modern bundler module resolution
packages/testing/src/types/index.ts	relaxed types to use any with index signatures to prevent conflicts with app-specific types
packages/testing/src/builders/workflow.builder.ts	converted to use any return type for build() method to be assignable to any app's workflow type
packages/testing/src/factories/block.factory.ts	changed all factory functions to return any type to accept any app type without conflicts
apps/sim/tsconfig.json	migrated to extend from shared tsconfig/nextjs.json, significantly reducing duplicate configuration
docker/app.Dockerfile	added tsconfig package to Docker build and updated isolated-vm path to match Bun's new structure
apps/sim/package.json	added tsconfig dependency and moved root-level dependencies here, alphabetized imports

Dev->>TSConfig: Add library.json (extends base + declarations, noEmit)
Dev->>TSConfig: Add library-build.json (extends base + emit)
Dev->>TSConfig: Define package.json exports
Note over Dev,Docker: Phase 2: Update Testing Package Types
Dev->>Pkgs: Relax testing package types to use 'any'
Dev->>Pkgs: Add eslint-disable for @typescript-eslint/no-explicit-any
Dev->>Pkgs: Update factories to return 'any' for flexibility
Dev->>Pkgs: Add nanoid dependency to testing package
Dev->>Pkgs: Update testing package tsconfig to extend @sim/tsconfig/library.json
Note over Dev,Docker: Phase 3: Migrate All TSConfigs
Dev->>Apps: Update apps/sim/tsconfig.json to extend @sim/tsconfig/nextjs.json
Dev->>Apps: Update apps/docs/tsconfig.json to extend @sim/tsconfig/nextjs.json
Dev->>Pkgs: Update packages/db to extend @sim/tsconfig/library.json
Dev->>Pkgs: Update packages/logger to extend @sim/tsconfig/library.json
Dev->>Pkgs: Update packages/cli to extend @sim/tsconfig/library-build.json
Dev->>Pkgs: Update packages/ts-sdk to extend @sim/tsconfig/library-build.json
Note over Dev,Docker: Phase 4: Fix App Test Type Errors
Dev->>Apps: Update utils.test.ts to use legacySubBlocks() helper
Dev->>Apps: Add explicit type assertions in store.test.ts
Dev->>Apps: Import operation types for proper casting
Note over Dev,Docker: Phase 5: Update Dependencies & Docker
Dev->>Root: Move misplaced dependencies from root to apps/sim
Dev->>Apps: Add @sim/tsconfig to all package devDependencies
Dev->>Docker: Add tsconfig package to Docker build stages
Dev->>Docker: Update isolated-vm path for Bun's new structure
Note over Dev,Docker: Phase 6: Branding Consistency
Dev->>Apps: Update User-Agent from "SimStudio" to "Sim" (11 files)
Note over Dev,Docker: Result: Centralized TS config, resolved type errors
