1 Best APIs for Multiple DB Support in Nigeria

Hasura is an open-source GraphQL and REST API engine that instantly generates production-ready APIs directly from your database schema — no manual API code required. Connect Hasura to a PostgreSQL database and within seconds you have a full GraphQL API with queries, mutations, and real-time subscriptions for every table and relationship in your schema. For Nigerian developers and startups who want to move quickly without writing repetitive CRUD API boilerplate, Hasura is one of the most powerful productivity tools in the modern backend development toolkit. Nigeria's startup ecosystem is characterized by small, fast-moving engineering teams that need to ship working products quickly while managing limited engineering resources. Building a backend API from scratch — designing endpoints, writing database queries, handling authentication, implementing pagination, and maintaining the code — takes significant time that could be spent on product differentiation and user experience. Hasura eliminates the most repetitive parts of this work, letting Nigerian developers focus on what makes their product unique. The core feature is automatic GraphQL API generation. When Hasura connects to a PostgreSQL database, it immediately exposes GraphQL queries (for reading data), mutations (for creating, updating, and deleting data), and subscriptions (for real-time data streaming) for every table. Relationships between tables are automatically reflected as nested GraphQL types — a users table with a related orders table can be queried in a single GraphQL request that returns users with their nested order arrays, with automatic SQL JOIN generation. Row-level permissions are one of Hasura's most important security features for Nigerian applications. Rather than implementing authorization logic in application code, permissions are defined in Hasura's console as rules: "A user can only read their own rows," "An admin can read all rows," "Guests can only read published records." These rules are enforced at the database query level, making it extremely difficult to accidentally expose data that should be private — a critical security guarantee for Nigerian fintech and health tech applications handling sensitive user data. Real-time subscriptions use WebSocket connections to stream data changes to clients. When a Nigerian analytics dashboard needs to update in real time as new orders come in, or when a chat application needs to display messages as they are sent, Hasura's subscriptions push updates to connected clients automatically without polling. This eliminates the need for Nigerian developers to build WebSocket server infrastructure and manage pub/sub systems. Event triggers allow Hasura to call external webhooks when database operations occur — when a new user is inserted, trigger an email welcome sequence; when an order is updated, notify the logistics system. This event-driven architecture enables Nigerian developers to build complex workflows without tightly coupling services. Hasura is self-hostable via Docker (free) or available as Hasura Cloud with a generous free tier of 60 requests per minute and 1 million operations per month. Hasura's Remote Schemas feature allows federating external GraphQL APIs into the Hasura gateway — making a unified GraphQL endpoint that combines database data with external API data in a single query. Nigerian applications that need to combine PostgreSQL data with third-party API responses can use Remote Schemas to build a unified data layer that resolves all queries from one endpoint. Hasura's event triggers fire webhooks on specific database operations (INSERT, UPDATE, DELETE on specified tables), enabling event-driven architectures where database changes automatically trigger downstream processes — sending notifications, updating caches, or initiating workflows. Nigerian fintech and e-commerce applications can use event triggers to ensure that every significant data change automatically propagates to all dependent systems reliably.
