Node bindings for Plaid
Official Node.js client for the Plaid financial data API, auto-generated from Plaid's OpenAPI spec. If you're building fintech in Node and need bank account linking, transactions, identity, or asset reports, this is the library you use — there's no real alternative.
Generated from the OpenAPI schema, so types stay in sync with the actual API without manual maintenance. Full TypeScript coverage means you get autocompletion on every request/response shape. The sandbox environment support is genuinely useful for development without touching real bank data. Error objects include structured fields (error_type, error_code, request_id) that map directly to Plaid's documented error taxonomy, making error handling tractable.
Auto-generated code means the internals are unreadable — debugging a weird request failure means stepping through Axios interceptors and mustache-generated classes, not human-written logic. Error handling has a gotcha: the full error object contains your API secret in error.config.headers, and the README buries this warning in a single line — easy to leak credentials in logs. No built-in retry logic or rate limit handling; you're on your own for RATE_LIMIT_EXCEEDED. The library locks you to a single API version (2020-09-14), so if Plaid ships a new version with breaking changes, a major bump is your only upgrade path.
