Faast.js is a TypeScript/JavaScript library that transforms ordinary modules into serverless cloud functions on AWS Lambda, handling packaging, infrastructure setup, and cleanup automatically. It enables massively parallel batch computing with thousands of concurrent invocations, real-time cost estimation, and a local mode for testing without cloud resources.
Use cases
- run batch jobs on thousands of cloud cores from JavaScript
- call AWS Lambda functions like regular async functions
- estimate the cost of serverless workloads in real time
- parallelize CPU-bound tasks across serverless functions
- test serverless functions locally without an AWS account
- compare Lambda memory configurations for cost and speed
- avoid managing infrastructure for ephemeral compute jobs
When to choose
- you want serverless batch computing from Node.js with zero infrastructure management
- you need to fan out thousands of parallel function invocations on AWS Lambda
- you want type-safe cloud function calls with first-class TypeScript support
- you need real-time cost snapshots and cost analysis for serverless workloads
When to avoid
- you need event-driven or always-on serverless services rather than batch invocation
- you require cloud providers other than AWS (only AWS and local providers are supported)
- your workload needs long-running processes beyond Lambda execution limits
- you need a managed platform or dashboard rather than a pure library
