MVHS Schedule

MVHS Schedule is an easy library to fetch the periods on any specific day. It returns an array of Periods (Period {start: Date; end: Date; period: string}) to represent periods. It will work no matter what timezone it is run in.

I use the firebase REST api to fetch the schedule and then I cache it to localstorage. It will refresh the data if it is older than a day. If there is an error anyway then it will use the cached data anyway, even if it's expired. If there is no cached data then it will throw an error.

Functions:

getScheduleFromDay(day: Date): Promise<string>

Returns a string of what schedule is on that day. Used internally by getPeriodsOnDay.

const schedule = getScheduleFromDay(new Date('11/15/2021'))
/* example output:
"Schedule A"
*/
getPeriodsFromSchedule(date: Date, schedule: String): Promise<Period[]>

Gets the periods for a schedule. The date is required to set the correct day for the returned period array's Date objects. Used internally in getPeriodsOnDay.

getPeriodsFromSchedule(new Date('11/15/2021'), 'Schedule A')
/* Example output:
[
  {
    start: "2020-11-15T00:00:00.000Z",
    end: "2020-11-15T01:00:00.000Z",
    period: "1"
  }
]
*/
getPeriodsOnDay(day: Date): Promise<Period[]>

Gets the periods on a day. Internally calls both getScheduleFromDay and getPeriodsFromSchedule.

getPeriodsOnDay(new Date('11/15/2021'))
/* Example output:
[
  {
    start: "2020-11-15T00:00:00.000Z",
    end: "2020-11-15T01:00:00.000Z",
    period: "1"
  }
]
*/
getPeriodsFromDayCount(day: Date, dayCount : Number) : Promise<Period[][]>

returns an array of array of Periods, one array for each day, starting with the input day and going forwards for dayCount days. Example:

getPeriodsFromDayCount(new Date('11/15/2021'), dayCount)
/* Example output:
[
  [
    {
      start: "2020-11-15T00:00:00.000Z",
      end: "2020-11-15T01:00:00.000Z",
      period: "1"
    }
  ]
]
*/
getTimeOfPeriod(period: number, date:Date): Promise<Period>

Gets the time of a period by calling getPeriodsOnDay and then returns a single Period object.

getTimeOfPeriod(1, new Date('11/15/2021'))
/* Example output:
{
  start: "2020-11-15T00:00:00.000Z",
  end: "2020-11-15T01:00:00.000Z",
  period: "1"
}

TSDX User Guide

If you’re new to TypeScript, checkout this handy cheatsheet

Commands

To run TSDX, use:

npm start # or yarn start

This builds to /dist and runs the project in watch mode so any edits you save inside src causes a rebuild to /dist.

To do a one-off build, use npm run build or yarn build.

To run tests, use npm test or yarn test.

Configuration

Code quality is set up for you with prettier, husky, and lint-staged. Adjust the respective fields in package.json accordingly.

Jest

Jest tests are set up to run with npm test or yarn test.

Bundle Analysis

size-limit is set up to calculate the real cost of your library with npm run size and visualize the bundle with npm run analyze.

Rollup

TSDX uses Rollup as a bundler and generates multiple rollup configs for various module formats and build settings. See Optimizations for details.

TypeScript

tsconfig.json is set up to interpret dom and esnext types, as well as react for jsx. Adjust according to your needs.

Continuous Integration

GitHub Actions

Two actions are added by default:

  • main which installs deps w/ cache, lints, tests, and builds on all pushes against a Node and OS matrix
  • size which comments cost comparison of your library on every pull request using size-limit

Optimizations

Please see the main tsdx optimizations docs. In particular, know that you can take advantage of development-only optimizations:

// ./types/index.d.ts
declare var __DEV__: boolean

// inside your code...
if (__DEV__) {
  console.log('foo')
}

Named Exports

Per Palmer Group guidelines, always use named exports. Code split inside your React app instead of your React library.
