Build the TaskFlow API Module

Create a NestJS/Fastify Tasks module and trace one request through the framework pipeline.

Build plan

Work through it one observable step at a time

01
Bootstrap Nest with Fastify and verify the listen address/port.
02
Create TasksModule and register it in AppModule.
03
Add TasksService and inject it into TasksController.
04
Implement `GET /tasks` with in-memory data first.
05
Add a validation pipe to one route parameter or DTO.
06
Add a simple guard and interceptor, then log the order in which the request passes them.
07
Add centralized exception handling for one deliberate error.
08
Add liveness/readiness endpoints and verify graceful shutdown.
09
Draw the actual request path based on the logs you observed.

Evidence

Do not rely on “it seems to work”

Evidence to collect

A clean Git diff or file-tree changeCommands used and their exit/resultBrowser, HTTP, database, test, container, or CI evidence that proves the behaviorOne deliberate failure, the evidence you used, and the root-cause fixA short explanation of why the final responsibility lives in the chosen layer

Project exit ticket

Close the project only when these are true

Completion

I can demonstrate every deliverable.I can reproduce one key part without the walkthrough.I can explain one trade-off I deliberately chose.I can show one failure that my tests, constraints, or runbook now protects against.
