Deploy your JavaScript app to AWS
Step-by-step deployment help for JavaScript apps on AWS. We fix JavaScript-specific deployment issues, configure AWS, and get your app live. From $19.
JavaScript issues we fix before deploying
Common JavaScript problems that affect AWS deployments.
Prototype pollution
AI-generated code merges user-supplied objects into prototypes via Object.assign or spread operators without sanitization, enabling property injection attacks.
Loose equality comparisons
Using == instead of === leads to type coercion bugs where '0' == false, null == undefined, and other non-obvious truthy/falsy comparisons cause silent logic errors.
Unhandled promise rejections
Async functions without try/catch or .catch() handlers cause unhandled rejection warnings and silent failures in production.
Global variable leaks
Missing 'const' or 'let' declarations create implicit globals that pollute the global scope and cause unpredictable behavior across modules.
AWS deployment issues we check for
Common AWS problems that break JavaScript apps in production.
IAM policies with wildcard permissions
AI-generated infrastructure code grants Action: '*' and Resource: '*' permissions, violating least-privilege principles and creating critical security exposure.
Security groups open to 0.0.0.0/0
Database and internal service security groups allow inbound traffic from any IP address, exposing RDS instances and backend services to the public internet.
S3 bucket policy allows public read
AI tools configure S3 buckets with public-read ACLs for convenience, inadvertently exposing private user data and application secrets.
Lambda cold starts degrading API performance
Infrequently called Lambda functions experience 3-10 second cold starts. AI-generated architectures don't configure provisioned concurrency or optimize bundle size.

Frequently asked questions
How do I deploy a JavaScript app to AWS?
We handle JavaScript deployments to AWS end to end. Start with our code audit ($19) to identify deployment blockers specific to your JavaScript project, then we configure AWS, fix issues, and get your app live in production.
What JavaScript issues affect AWS deployments?
JavaScript projects commonly have prototype pollution and loose equality comparisons. On AWS, these combine with iam policies with wildcard permissions and security groups open to 0.0.0.0/0 to cause deployment failures.
Can SpringCode deploy my JavaScript project to AWS?
Yes. We specialize in deploying JavaScript applications to AWS. We audit your codebase for JavaScript-specific issues, configure AWS correctly, and handle the full deployment so your app runs reliably in production.
What does JavaScript deployment to AWS cost?
Our code audit ($19) identifies all AWS deployment blockers in your JavaScript project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
