Super solid Happy Thoughts API — clean structure, good validation, authentication works well, and the routes are easy to follow. No major issues. Nice job!
| required: [true, "Email is required"], | ||
| unique: true, | ||
| match: [/.+@.+\..+/, "Please enter a valid email"], | ||
| }, |

Good validation setup here , nice requirements and helpful error messages. makes the API safer and easier to debug.
| const token = req.header("Authorization"); | ||
| if (!token) { | ||
| return res.status(401).json({ error: "Not logged in" }); | ||
| } |

Nice reusable auth middleware. Easy to follow and attaching the user to req.user makes the protected routes very readable.
| } | ||
| if (String(thought.user) !== String(req.user._id)) { | ||
| return res.status(403).json({ error: "You can only edit your own thoughts" }); | ||
| } |

This works fine. One alternative could be using thought.user.equals(req.user._id), which is a bit more Mongoose-style for comparing ObjectIds.

Nice clear route logic here. Easy for me to follow the flow from request to database query and toresponse.

Good middleware setup. Makes sure the API can properly read JSON from the frontend.
| required: [true, "Message is required"], | ||
| minlength: [5, "Message must be at least 5 characters"], | ||
| maxlength: [140, "Message must be at most 140 characters"], | ||
| }, |
| { method: "POST", path: "/thoughts/:id/like", description: "Like a thought" }, | ||
| ], | ||
| }); | ||
| }); |

Nice idea documenting the API routes here. Makes it easy to see what endpoints exist.
