Explore GraphQL, a query language and runtime for APIs, and learn how queries, mutations, and schemas enable precise data requests and a contract between client and server.
Add a GraphQL mutation to create products with an input type, return a product array, and define a resolver, then explore Apollo GraphQL with Express and TypeScript.
Install the TypeScript compiler with npm, ensuring Node is installed from nodejs.org, then initialize tsconfig.json with tsc --init and set es6, commonjs, and dist.
Define an auth resolvers object with a signup mutation in an auth/resolvers.ts file, handling async signup via input, parent, and context, and prepare for TypeScript type generation from the schema.
Create the app data source in the source folder, configure a local Postgres database via Docker (localhost:5432, admin/admin, main database), and define entities from the dist folder.
Define and implement the sign in mutation and input, verify user by email with a query builder, compare passwords with bcrypt, and return a JWT while hiding passwords in GraphQL.
Create a room service with a repository to persist rooms and initial messages. Then add messages to existing rooms using a query builder to append to a jsonb messages array.
Test and secure a GraphQL API by running Postgres, starting the server, and using Apollo Sandbox to sign in, create rooms, and send messages with JWT authentication.
Add validation to your project using the class-validator package, applying email and min length decorators to user properties, exploring decorators for URL, array, and case checks, and handling validation errors.
Explore real-time messaging with socket.io, enabling instant delivery of new messages and room updates between web clients and servers without page refresh.
