CSC73010 – Programming Mobile Systems

Assignment 1 (S3 2020)

This assignment is due on Friday, 18 December 2020, 11:00 pm. You should submit your source code as a ZIP

archive for all parts of the assignment to assignment 1 submission link in the unit site. If the file size is too large

to upload to submission link, please send the ZIP file via e-mail or via a method specified by your tutor. Note that

marks will be deducted for poorly structured or uncommented code. All source code files submitted must include

title comments that at least identify the author and the assignment part. The separate parts of the assignment are

to be submitted in separate subdirectories (e.g. Part1, Part2 etc.) – submissions that ignore this instruction and

leave all assignment files in one directory will be penalised.

Please note that this assignment will be due after the weekly sessions have covered the last of the required

materials. Do not leave this assignment to the last minute – you can start on it while concepts are fresh in your

mind. You may start Part 1 before you have studied all of the required materials. If you require an extension, you

must apply to your tutor before the due date to be considered. Unless an extension is approved, there is a penalty

(see Unit Information Guide).

This assignment requires you to develop an application using TypeScript for Part 1, and Angular for Part 2, to

demonstrate your knowledge of the TypeScript language and Angular framework. Your apps should be standalone

apps without server contact for data. The app will not save data after the browser window is closed, but you

will need to maintain a JavaScript structure (e.g. JavaScript object) so that changes made remain while the browser

window is open.

Part 2 can be an expansion of Part 1 though you can start again from scratch if you wish. It is recommended that

you save your Part 1 before you start modifying it for Part 2. For lesser marks, you can divide your assignment

into several smaller HTML pages to demonstrate the different aspects without having everything working

together. This is not the preferred method.

Part 1 – Basic TypeScript App (12 marks)

The aim is to develop a simple one-page TypeScript app for a library to maintain a small database of book

information while the browser window is open. You can initialise your app with hardcoded data, or you can start

with an empty data structure. Types are important in your code; however, there is no need to type everything, and

general applicability of typing is as you have seen in the study guide. For example, there is no need to define a

function type in a function definition as TypeScript and the reader can easily deduce the type from the function

definition. You will have to type parameters and return values, though. Marks may be deducted for too few type

definitions, i.e. writing JavaScript instead of TypeScript.

The book data has the following fields:

? ISBN

? Title

? Author

? Publication Date

? Number of Pages

? Availability (“Paperback”, “eBook”, “Audio book”)

? Edition

The data has the following requirements (1 mark):

- Each record must have a value for all fields. Only the Edition field can be blank.

- The book Availability must be one of the options shown.

- An ISBN can only be entered and saved once (it must be unique for each book).

Your database would probably be a TypeScript array of JavaScript objects, each of which has properties

corresponding to the above fields. You can use another data structure if you wish, but types will be necessary to

ensure the integrity of the data (1 mark).

Your app should implement:

- A way to edit book data (2 marks). Remember you do not have to permanently save the data between

browser sessions, but you do have to save it while the app is active. HTML form widgets are the easiest

here.

- A way to add a new book information (2 marks). Consider re-using the edit form above, and it will require

careful thought so as not to confuse the user.

- A way to delete an individual book with a “Do you really want to…” interaction to reduce accidental

deletions (2 marks).

- A way to search the book by the ISBN field (2 marks). This will probably be done with an HTML list,

but you may use other techniques (e.g. implement a search text field – harder).

Your app should also:

- Provide an interface equally viewable by narrow and wider mobile screens (it will be tested). Note that

this is just a request to keep your app simple and displayable on narrow screen as well as possibly wider

screens. You can put links in a long page to navigate your app on narrow screens. This will be important

when we get to mobile device apps later in the unit (1 mark).

- Use interactive features (e.g. use innerHTML assignments) to improve user experience (not alert()

calls!). You are expected to do error messages where necessary (1 mark).

Part 2 – Expand the App (13 marks)

Modify the app from part 1 to become a multipage Angular app. For example, place the add record on a separate

page to the search facility. You can use as many pages as you like but don’t forget to use an error page (for

malformed URLs), an Information page, e.g. about the app and have your name as an app developer. A Help page

showing how to use the app would be nice as well.

Marks are allocated as follows:

1. Having a working Angular app with appropriate Angular coding (3 marks). Minimally the app will have

one component and one module, but to implement the following requirements, you will need more

components.

2. Using Angular forms (3 marks). This is separate to the multipage facility. If you just add Angular code

to the one-page TypeScript app from Part 1, you have not used Angular forms.

3. The multipage facility using the Angular router (3 marks). This includes the navigation between pages,

error indicators and no broken links.

4. Add at least one help button on each page that shows appropriate help messages. You should make

interaction with the help facility as easy as possible. Also add helpful information, including error

messages, when data entry is incorrect (3 marks).

5. Use of CSS styles (1 mark). Just use them, there are no marks for artistic design. We are looking for the

ability to use styles. Feel free to use styles you find in the Angular documentation or other on-line sources

(a reference to the original designer should be made in your code if appropriate).
