This project is an interview assignment with the following requirements:
- User comes to main page and sees a list of todos.
- Creation/Updating/Deleteion must be done without page refresh.
- Size of js must be less then 50Mb (gzipped).
- Amount of dependencies must be minimal.
- Todos must be saved into SQLite database.
- Tables in DB must be created with migrations.
In this project I am featuring the following:
- Typescript and Node.js
- No external dependencies in server or client side code.
- Lightweight – Only 8K js
- Layered server architecture: router/view/model/sqlite layers.
- Fully Ajax driven – no page refresh
- Create/Read/Update/Delete features are in place and are RESTful
- All code is OOP
- In-house built simple migration feature that keeps track of order and version
- Secure. Access restricted to a clearly defined set of resources
- Settings, libraries, sqlite adapter are abstracted into separate classes
- Client side HTML is generated with JS class on–the–fly.
- Fast and furious time of completion of project: 1.5 days.
To build service, install sqlite3:
npm install sqlite3
To run typescript transpiler:
npx tsc
To start service run:
node js/server/app.js
The migrations run on every server start:
