generateDays

Generates a list of days, each with time slots between a given start and end time, skipping weekends.

Use Case

This utility is designed to help create mock or real meetingsByDay data compatible with your MeetingSelector component — especially useful in development, testing, or preview environments.

Function Signature

generateDays(
  date: Date,
  nbDays: number,
  startTime: Time,
  endTime: Time,
  interval: number
): MeetingsByDayGenerated[]

Parameters

Name	Type	Description
date	Date	The starting date for slot generation.
nbDays	number	Number of weekdays to generate (weekends are skipped).
startTime	Time	Time of day when the slots should start (e.g. { hours: 9, minutes: 0 }).
endTime	Time	Time of day when the slots should end.
interval	number	Length of each slot in minutes.

Returns

type MeetingsByDayGenerated = {
  date: Date;
  slots: {
    date: Date;
  }[];
};

An array of objects, each containing:

• A date
• An array of slot objects ({ date: Date }) between startTime and endTime spaced by interval

Behavior

• The first day starts immediately or from startTime, depending on the current time.
• All time slots are rounded to the next closest interval.
• Times are set with zero seconds and milliseconds for consistency.

Example

import { generateDays } from '<framework>-meeting-selector';

const days = generateDays(
  new Date(), // today
  5, // generate 5 weekdays
  { hours: 9, minutes: 0 }, // start at 09:00
  { hours: 17, minutes: 0 }, // end at 17:00
  30 // 30-minute slots
);

console.log(days);
/*
[
  {
    date: 2025-07-16T00:00:00.000Z,
    slots: [
      { date: 2025-07-16T09:00:00.000Z },
      { date: 2025-07-16T09:30:00.000Z },
      ...
    ]
  },
  ...
]
