Mentor Meeting Planner with Next.js: A 2027 Project Guide

A student scheduling guidance needs a trustworthy answer to a small operational question: how many confirmed meeting minutes are planned by topic? This Next.js project turns that question into a server-and-client web feature. The useful result is a traceable decision rule, a clear output and evidence that a change behaves as expected.

This is a 2027 study-edition project brief. All example records and operational situations are fictional. Start with basic Next.js knowledge, the ability to inspect structured data and a local practice environment. The complete first version should answer the stated question before adding accounts, real integrations or additional screens.

Define the project rule

Confirmed meeting minutes represent booked time. Cancelling a meeting removes booked minutes, while rescheduling changes the existing record rather than creating another active copy. For this exercise, one row represents one meeting. The stable key is record_id; meeting_topic is the grouping or filtering label. The numeric duration_minutes field uses minutes. Accepted states are requested, confirmed, cancelled.

The summary selects status confirmed and applies sum to the selected numeric values. Keep this definition visible in the interface, response or report so another learner can reproduce it. Use positive finite values in the starter fixture and define any future zero or missing-value policy explicitly.

Choose the Next.js approach

Decide which information belongs on the server and which interaction needs a client component. Treat every client value as untrusted when it reaches a server boundary. Keep secrets out of browser bundles and write down how data freshness should behave before choosing a caching strategy. Check the documentation matching the installed framework version.

The three design decisions to explain in your project notes are:

• Server and client responsibility. Apply this choice to meeting records and explain its effect on duration_minutes.
• Explicit freshness expectations. Apply this choice to meeting records and explain its effect on duration_minutes.
• Safe input handling at server boundaries. Apply this choice to meeting records and explain its effect on duration_minutes.

Work through a small sample

The three records below are deliberately small enough to inspect by hand. They are a compact specification for the data shape and expected result, and can later be expanded into a larger synthetic fixture.

[
  {
    "record_id": "mentor-meetings-01",
    "meeting_topic": "Project Feedback",
    "duration_minutes": 25,
    "status": "confirmed",
    "recorded_on": "2027-01-04"
  },
  {
    "record_id": "mentor-meetings-02",
    "meeting_topic": "Portfolio Review",
    "duration_minutes": 40,
    "status": "requested",
    "recorded_on": "2027-01-05"
  },
  {
    "record_id": "mentor-meetings-03",
    "meeting_topic": "Debugging Help",
    "duration_minutes": 15,
    "status": "confirmed",
    "recorded_on": "2027-01-06"
  }
]

Only the first and third records match confirmed. Their duration_minutes values are 25 and 15; the full-fixture result is 40 minutes, with 2 matching records. Selecting meeting_topic = Project Feedback leaves the first record, so the result becomes 25 minutes, with 1 match. This provides two independent checks for the filter and aggregation.

The full-fixture output contract is:

{
  "matching_count": 2,
  "operation": "sum",
  "value": 40,
  "unit": "minutes"
}

Check the result by meeting_topic

The overall figure answers the all-records version of the question. Grouping by meeting_topic produces the following separate expectations, using the same confirmed rule. The middle group has a record in the source fixture but no qualifying observation.

Use this breakdown when answering the group-level question. Compare like-for-like units and keep the matching count visible, especially for averages. A different filter changes which records enter the calculation; it does not change the meaning of the metric.

The code blocks describe sample data and an expected result. Implement the surrounding feature using the installed version of your chosen tools, then save the actual run evidence separately from these expectations.

Build the feature in three passes

1. Build the information hierarchy

Show the meeting_topic, duration_minutes and status of each meeting with visible labels. Place the meeting_topic filter beside the summary it controls. A reader should understand the unit, minutes, without needing to inspect the fixture.

2. Connect the filter to one source of data

Derive the selected meeting records and their sum from the same collection. Keep the confirmed rule explicit. Render an empty-match explanation with the applied filter rather than showing a blank chart that looks broken.

3. Demonstrate an interaction and recovery

Use the first sample label as a filter, reset it, and try a value with no match. If this feature includes saving, provide a pending state and an error state. A static prototype should identify the interaction that still needs implementation.

Find the mistake before polishing the result

A useful defect to introduce deliberately is: Rescheduling creates two confirmed copies of the same meeting. First reproduce it against the fixture, then identify the smallest rule or state transition that explains the mismatch. Fix that boundary and rerun the full-fixture and selected-label examples. This creates a stronger explanation than changing several unrelated parts until the screen looks right.

The scenario-specific acceptance check is: Reschedule the fixture meeting and preserve one stable identifier. Preserve before-and-after evidence. Add a missing meeting_topic, a negative duration_minutes, an unrecognised status and a duplicate record_id as separate invalid cases. Define the rejection or duplicate-handling policy before testing, and verify that invalid input does not silently change valid existing records.

Check the Next.js concerns as well:

• A refreshed page must show the intended state.
• Browser code must not expose server credentials.
• A cached response must not mix two users' data.

For an empty filter match, the expected sum value is 0. Keep matching_count at zero. This distinction prevents an empty dataset from being interpreted as a measured observation.

Explain the finished work in a portfolio

Show the student scheduling guidance question, the record definition and the expected calculation first. Then demonstrate a meeting_topic filter and the acceptance check. Include the fixture, setup instructions, chosen tool versions, actual test output and one remaining limitation in the repository. If you show a screenshot, pair it with the input that produced it. Another learner should be able to repeat the same result from a clean checkout.

For a focused extension, add a second meeting_topic selection and compare the two groups using the same rule. Specify how missing groups appear and keep the original fixture as a regression case. Expand scope only after the current calculation, state handling and recovery path remain understandable.

Questions learners often ask

Which meeting records belong in the result?

Select records whose status is exactly confirmed and that satisfy the chosen meeting_topic filter. Other states remain in the source data and can have separate summaries. Follow the domain rule above when a record changes state.

What should happen when no records match?

Return a zero total with a matching count of zero and a clear empty-result message. Keep the applied filter visible so the user can change it. Avoid using a loading indicator for a completed request that simply has no matching data.

How can I prove the duration_minutes result is correct?

Reconcile the first and third sample records, then repeat the calculation for Project Feedback alone. Save both expected and actual outputs, and rerun the scenario-specific acceptance check after making a change.
