SJTU CS1951 lab assignment

Assignment details: https://github.com/ACMClassCourse-2021/TicketSystem

Getting Started

You need CMake (≥ v3.16) and a C++ compiler capable of C++ 20. We use g++ and clang++. To build the project, run bin/build from the root directory. More details can be found in HACKING.md.

A Node.js binding is available. To build the binding, you need to have a recent version of Node.js and npm, and cmake-js on your $PATH. To build the binding, run bin/build-node from the root directory.

This project runs only on *nix systems (i.e. not Microsoft Windows).

Node-C++ interop: Alan-Liang

Code Structure

lib/ contains library stuff unrelated to business logic. It is written to replace many useful utilities in the C++ STL, and to implement file storage.

src/ contains business logic of the ticket system. The main function performs a Read-Eval-Print Loop (REPL). The node module provides an interface to the Node platform. The command parser parses the command string into command arguments, and main dispatches the command.

Frontend code is to be written in JavaScript utilizing the Vue.js library. A backend-for-frontend (BFF), also written in JavaScript and to be ran in the Node runtime, acts as the intermediary between frontend API calls and the C++ backend. It also serves static assets. Optionally, a reverse proxy could be used to achieve load balancing, HTTPS, logging or other purposes.

The frontend would be a single-page application (SPA). The frontend code would fetch raw data in JSON format from the BFF, and turn it into a DOM structure to be rendered in the browser. Detailed UI/UX design is TBD.

For the detailed code structure, see docs/refman.pdf or https://faketicket-docs-demo.vercel.app/, both generated by Doxygen. They contain the same contents. You can generate these docs by running doxygen in the root directory of this repository.

SJTU CS1951 lab assignment
Assignment details:
https://github.com/ACMClassCourse-2021/TicketSystem
Getting Started
You need CMake (≥ v3.16) and a C++ compiler capable of C++
20. We use g++ and clang++. To build the project, run
bin/build from the root directory. More details can be
found in HACKING.md.
A Node.js binding is available. To build the binding, you
need to have a recent version of Node.js and npm, and
cmake-js on your $PATH. To build the binding,
run bin/build-node from the root directory.
This project runs only on *nix systems (i.e. not Microsoft
Windows).
Code Owners
Overall structure: Alan-Liang

Library utilities: Alan-Liang

Misc, Order, User, Parser: Alan-Liang

Rollback, Train: BLeaves

Frontend:

UI & API Design, Implementation, BFF: BLeaves

Node-C++ interop: Alan-Liang
Code Structure
lib/ contains library stuff unrelated to business logic.
It is written to replace many useful utilities in the C++
STL, and to implement file storage.
src/ contains business logic of the ticket system. The
main function performs a Read-Eval-Print Loop (REPL).
The node module provides an interface to the Node platform.
The command parser parses the command string into command
arguments, and main dispatches the command.
Frontend code is to be written in JavaScript utilizing the
Vue.js library. A backend-for-frontend (BFF), also written
in JavaScript and to be ran in the Node runtime, acts as the
intermediary between frontend API calls and the C++ backend.
It also serves static assets. Optionally, a reverse proxy
could be used to achieve load balancing, HTTPS, logging or
other purposes.
The frontend would be a single-page application (SPA). The
frontend code would fetch raw data in JSON format from the
BFF, and turn it into a DOM structure to be rendered in the
browser. Detailed UI/UX design is TBD.
For the detailed code structure, see docs/refman.pdf or
https://faketicket-docs-demo.vercel.app/, both generated
by Doxygen. They contain the
same contents. You can generate these docs by running
doxygen in the root directory of this repository.
