MicroFrontends

Adding eslint

1. In VScode extensions remove Tslint and install Eslint (exact extension name: dbaeumer.vscode-eslint)
2. In a project root remove tslint.json
3. copy .eslintrc.js
4. run: npm i -D eslint @typescript-eslint/parser @typescript-eslint/eslint-plugin eslint-plugin-jsdoc
5. uninstall tslint, tslint-sonarts: npm un tslint tslint-sonarts

Frontend handling events

There are Instant events and Delayed Events:

• Instant events (t <= 5 seconds) which are used frequently, like getting data for table. We confirm instant events and let them into EventBus.
• Delayed events (t >= 5 seconds) which are used rarely, like long calculations. User confirms them.

Environment Table

Environment	Database-Backend	Login	Shell	Nginx
Production	Real	Real	Yes	Yes
Staging	Stage[1]	Stage	Yes	Yes
Development	Local	Local	Yes	Yes
Isolated	Local	None	No	No
Solo	Mock[2]	None	No	No

1. As close to real as possbile, maybe even a copy with snapshots done periodically, to recover after tests or failures
2. Solo is intended to check for visual feel only, thus microfrontend should be self sustained (no connections) and instead of calling to real backend should use mocks which might as well be used by tests.

Production

The bussiness environment

Staging (not implemented)

Environment for regression tests after unit and integration tests are done; this environment should be set up just as production one: publically available for clients and our testing team to do regression tests

Development

Same as production but set up locally for developing new features

Isolated

Used for testing microfrontend alone but with connection to development backend/database

Solo

Used for writing initial view which does not require anything else in the environment. In order for it to work, mock services should conditionally injected.

Development setup (all micro frontends):

1. cd launcher and run npm run watch (assuming micro frontends were installed), which will start watch on: MaterialReceipts, Occupation, Personnel and Shell micro frontends.
2. cd ReverseProxy and run ./nginx.exe (which will start server on localhost:80) then control from other console using ./nginx.exe -s stop or ./nginx.exe -s reload

Development setup (one by one micro frotnend):

1. cd <desired project>
2. npm i skip if you have already installed everything
3. npm run start (it does ng serve but with unique port)

Adding new micro frontend

1. cd installer
2. npm ci to install same dependecy tree, without modifying anything
3. npm run build will build
4. npm run start will start script, follow instructions
5. currently shell and menu integration is not implemented (you have to manually ad to shell and menu)

Authentication

Enable

1. In backend database ApiGateway -> UserValidTokens -> set ALL entries' field IsDeleted to false
2. In every frontend enable in environments/environment.ts change EnvironmentTypes enum to Development or higher (prod, stage)

Disable

1. In backend database ApiGateway -> UserValidTokens -> set ALL entries' field IsDeleted to true
2. In every frontend enable in environments/environment.ts change EnvironmentTypes enum to Isolated or lower
