Migrate to ES6 modules

Configure project to use ES6 modules to enable top-level await
capabilities. This change helps project to align well with modern JS
standards.

- Set `type` to `module` in `package.json`.
- Use import/export syntax in Cypress configuration files.
- Rename configurations files that do not support modules to use
  the `.cjs` extension:
  - `vue.config.js` to `vue.config.cjs` (vuejs/vue-cli#4477).
  - `babel.config.js` to `babel.config.cjs (babel/babel-loader#894)
  - `.eslintrc.js` to `.eslintrc.cjs` (eslint/eslint#13440,
    eslint/eslint#14137)
  - `postcss.config.js` to `postcss.config.cjs` (postcss/postcss#1771)
- Provide a workaround for Vue CLI & Mocha ES6 modules conflict in
  Vue configuration file (vuejs/vue-cli#7417).

+Love your input! Contributing to this project should be as easy and transparent as possible, whether it's:
+
+- reporting a bug,
+- discussing the current state of the code,
+- submitting a fix,
+- proposing new features,
+- or becoming a maintainer.
+
+As a small open source project with small community, it can sometimes take a long time to address the issues so please be patient.
 
 ## Pull request process
 
-- [GitHub flow](https://guides.github.com/introduction/flow/index.html) with [GitOps](./img/architecture/gitops.png) is used
-- Your pull requests are actively welcomed.
-- The steps:
-  1. Fork the repo and create your branch from master.
-  2. If you've added code that should be tested, add tests.
-  3. If you've changed APIs, update the documentation.
-  4. Ensure the test suite passes.
-  5. Make sure your code lints.
-  6. Issue that pull request!
-- 🙏 DO
-  - Document your changes in the pull request
-- ❗ DON'T
-  - Do not update the versions, current version is only [set by the maintainer](./img/architecture/gitops.png) and updated automatically by [bump-everywhere](https://github.com/undergroundwires/bump-everywhere)
+Your pull requests are actively welcomed. We collaborate using [GitHub flow](https://docs.github.com/en/get-started/quickstart/github-flow).
+
+The steps:
+
+1. Fork the repo and create your branch from master.
+2. If you've added code that requires testing, add tests. See [tests.md](./docs/tests.md).
+3. If you've done a major change, update the documentation. See [docs/](./docs/).
+4. Ensure the test suite passes. See [development.md | Testing](./docs/development.md#testing) for commands.
+5. Make sure your code lints.See [development.md | Linting](./docs/development.md#linting) for commands.
+6. Issue that pull request!
+
+**🙏 DO:**
+
+- Document why (what you're trying to solve) rather than what in the pull request.
+
+**❗ DON'T:**
+
+- Do not update the versions, current version is [set by the maintainer](./docs/ci-cd.md#gitops) and updated automatically by [bump-everywhere](https://github.com/undergroundwires/bump-everywhere).
+
+Automated pipelines will run to control your PR and they will publish your code once the maintainer merges your PR.
+
+📖 You can read more in [ci-cd.md](./docs/ci-cd.md).
+
+## Extend scripts
+
+Here's quick information for you who want to add more scripts.
+
+You have two alternatives:
+
+1. [Create an issue](https://github.com/undergroundwires/privacy.sexy/issues/new/choose) and ask for someone else to add the script for you.
+2. Or send a PR yourself. This would make it faster to get your code into the project. You need to add scripts to related OS in [collections](src/application/collections/) folder. Then you'd sent a pull request, see [pull request process](#pull-request-process).
+   - 📖 If you're unsure about the syntax, check [collection-files.md](docs/collection-files.md).
+   - 📖 If you wish to use templates, use [templating.md](./docs/templating.md).

-- Free (both free as in beer and free as in speech)
-- No need to run any compiled software that has access to your system, just run the generated scripts
-- Have full visibility into what the tweaks do as you enable them
-- Ability to revert (undo) applied scripts
-- Everything is transparent: both application and its infrastructure are open-source and automated
-- Easily extendable with [own powerful templating language](./docs/templating.md)
-- Each script is independently executable without cross-dependencies

+- [parsing and compiling](#parsing-and-compiling) the [application data](#application-data).
+
+📖 Refer to [architecture.md | Layered Application](./architecture.md#layered-application) to read more about the layered architecture.
 
 ## Structure
 
-- [`/src/` **`application/`**](./../src/application/): Contains all application related code.
-  - [**`collections/`**](./../src/application/collections/): Holds [collection files](./collection-files.md)
-  - [**`Common/`**](./../src/application/Common/): Contains common functionality that is shared in application layer.
-  - `..`: other classes are categorized using folders-by-feature structure
+Application layer code exists in [`/src/application`](./../src/application/) and includes following structure:
+
+- [**`collections/`**](./../src/application/collections/): Holds [collection files](./collection-files.md).
+- [**`Common/`**](./../src/application/Common/): Contains common functionality in application layer.
+- `...`: rest of the application layer source code organized using folders-by-feature structure.
 
 ## Application state
 
-- [ApplicationContext.ts](./../src/application/Context/ApplicationContext.ts) holds the [CategoryCollectionState](./../src/application/Context/State/CategoryCollectionState.ts) for each OS
-- Uses [state pattern](https://en.wikipedia.org/wiki/State_pattern)
-- Same instance is shared throughout the application to ensure consistent state
-- 📖 See [Application State | Presentation layer](./presentation.md#application-state) to read more about how the state should be managed by the presentation layer.
-- 📖 See [ApplicationContext.ts](./../src/application/Context/ApplicationContext.ts) to start diving into the state code.
+It uses [state pattern](https://en.wikipedia.org/wiki/State_pattern) with context and state objects. [`ApplicationContext.ts`](./../src/application/Context/ApplicationContext.ts) the "Context" of state pattern provides an instance of [`CategoryCollectionState.ts`](./../src/application/Context/State/CategoryCollectionState.ts) (the "State" of the state pattern) for every supported collection.
+
+Presentation layer uses a singleton (same instance of) [`ApplicationContext.ts`](./../src/application/Context/ApplicationContext.ts) throughout the application to ensure consistent state.
+
+📖 Refer to [architecture.md | Application State](./architecture.md#application-state) to get an overview of event handling and [presentation.md | Application State](./presentation.md#application-state) for deeper look into how the presentation layer manages state.
 
 ## Application data
 
-- Compiled to [`Application`](./../src/domain/Application.ts) domain object.
-- The scripts are defined and controlled in different data files per OS
-- Enables [data-driven programming](https://en.wikipedia.org/wiki/Data-driven_programming) and easier contributions
-- Application data is defined in collection files and
-- 📖 See [Application data | Presentation layer](./presentation.md#application-data) to read how the application data is read by the presentation layer.
-- 📖 See [collection files documentation](./collection-files.md) to read more about how the data files are structured/defined and see [collection yaml files](./../src/application/collections/) to directly check the code.
+Application data is collection files using YAML. You can refer to [collection-files.md](./collection-files.md) to read more about the scheme and structure of application data files. You can also check the source code [collection yaml files](./../src/application/collections/) to directly see the application data using that scheme.
 
-## Parsing
+Application layer [parses and compiles](#parsing-and-compiling) application data into [`Application`](./../src/domain/Application.ts)). Once parsed, application layer provides the necessary functionality to presentation layer based on the application data. You can read more about how presentation layer consumes the application data in [presentation.md | Application Data](./presentation.md#application-data).
 
-- Application data is parsed to domain object [`Application.ts`](./../src/domain/Application.ts)
-- Steps
-  1. (Compile time) Load application data from [collection yaml files](./../src/application/collections/) using webpack loader
-  2. (Runtime) Parse and compile application and make it available to presentation layer by [`ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts)
+Application layer enables [data-driven programming](https://en.wikipedia.org/wiki/Data-driven_programming) by leveraging the data to the rest of the source code. It makes it easy for community to contribute on the project by using a declarative language used in collection files.
 
-### Compiling
+### Parsing and compiling
 
-- Parsing the application files includes compiling scripts using [collection file defined functions](./collection-files.md#function)
-- To extend the syntax:
-  1. Add a new parser under [SyntaxParsers](./../src/application/Parser/Script/Compiler/Expressions/SyntaxParsers) where you can look at other parsers to understand more.
-  2. Register your in [CompositeExpressionParser](./../src/application/Parser/Script/Compiler/Expressions/Parser/CompositeExpressionParser.ts)
+Application layer parses the application data to compile the domain object [`Application.ts`](./../src/domain/Application.ts).
+
+A webpack loader loads (or injects) application data ([collection yaml files](./../src/application/collections/)) into the application layer in compile time. Application layer ([`ApplicationFactory.ts`](./../src/application/ApplicationFactory.ts)) parses and compiles this data in runtime.
+
+Application layer compiles templating syntax during parsing to create the end scripts. You can read more about templating syntax in [templating.md](./templating.md) and how application data uses them through functions in [collection-files.md | Function](./collection-files.md#function).

+# Architecture overview
+
+This repository consists of:
+
+- A [layered application](#layered-application).
+- [AWS infrastructure](#aws-infrastructure) as code and instructions to host the website.
+- [GitOps](#gitops) practices for development, maintenance and deployment.
+
+## Layered application
+
+Application is
+
+- powered by **TypeScript**, **Vue.js** and **Electron** 💪,
+- and driven by **Domain-driven design**, **Event-driven architecture**, **Data-driven programming** concepts.
+
+Application uses highly decoupled models & services in different DDD layers:
+
+- presentation layer (see [presentation.md](./presentation.md)),
+- application layer (see [application.md](./application.md)),
+- and domain layer.
+
+Application layer depends on and consumes domain layer. [Presentation layer](./presentation.md) consumes and depends on application layer along with domain layer. Application and presentation layers can communicate through domain model.
+
+![DDD + vue.js](./../img/architecture/app-ddd.png)
+
+### Application state
+
+State handling uses an event-driven subscription model to signal state changes and special functions to register changes. It does not depend on third party packages.
+
+The presentation layer can read and modify state through the context. State changes trigger events that components can subscribe to for reactivity.
+
+Each layer treat application layer differently.
+
+![State](./../img/architecture/app-state.png)
+
+*[Presentation layer](./presentation.md)*:
+
+- Each component holds their own state about presentation-related data.
+- Components register shared state changes into application state using functions.
+- Components listen to shared state changes using event subscriptions.
+- 📖 Read more: [presentation.md | Application state](./presentation.md#application-state).
+
+*[Application layer](./application.md)*:
+
+- Stores the application-specific state.
+- The state it exposed for read with getter functions and set using setter functions, setter functions also fire application events that allows other parts of application and the view in presentation layer to react.
+- So state is mutable, and fires related events when mutated.
+- 📖 Read more: [application.md | Application state](./application.md#application-state).
+
+It's comparable with `flux`, `vuex`, and `pinia`. A difference is that mutable application layer state in privacy.sexy is mutable and lies in single "store" that holds app state and logic. The "actions" mutate the state directly which in turns act as dispatcher to notify its own event subscriptions (callbacks).
+
+## AWS infrastructure
+
+The web-site runs on serverless AWS infrastructure. Infrastructure is open-source and deployed as code. [aws-static-site-with-cd](https://github.com/undergroundwires/aws-static-site-with-cd) project includes the source code.

+# Development
+
+Before your commit, a good practice is to:
+
+1. [Run unit tests](#testing)
+2. [Lint your code](#linting)
+
+You could run other types of tests as well, but they may take longer time and overkill for your changes. Automated actions executes the tests for a pull request or change in the main branch. See [ci-cd.md](./ci-cd.md) for more information.
+
+## Commands
+
+### Prerequisites
+
+- Install node >15.x.
+- Install dependencies using `npm install`.
+
+### Testing
+
+- Run unit tests: `npm run test:unit`
+- Run integration tests: `npm run test:integration`
+- Run e2e (end-to-end) tests
+  - Interactive mode with GUI: `npm run test:e2e`
+  - Headless mode without GUI: `npm run test:e2e -- --headless`
+
+📖 Read more about testing in [tests](./tests.md).
+
+### Linting
+
+- Lint all (recommended 💡): `npm run lint`
+- Markdown: `npm run lint:md`
+- Markdown consistency `npm run lint:md:consistency`
+- Markdown relative URLs: `npm run lint:md:relative-urls`
+- JavaScript/TypeScript: `npm run lint:eslint`
+- Yaml: `npm run lint:yaml`
+
+### Running
+
+- Run in local server: `npm run serve`
+  - 💡 Meant for local development with features such as hot-reloading.
+- Run using Docker:

 # Presentation layer
 
-- Consists of Vue.js components and other UI-related code.
-- Desktop application is created using [Electron](https://www.electronjs.org/).
-- Event driven as in components simply listens to events from the state and act accordingly.
+The presentation layer handles UI concerns using Vue as JavaScript framework and Electron to provide desktop functionality.
+
+It reflects the [application state](./application.md#application-state) and allows user interactions to modify it. Components manage their own local UI state.
+
+The presentation layer uses an event-driven architecture for bidirectional reactivity between the application state and UI. State change events flow bottom-up to trigger UI updates, while user events flow top-down through components, some ultimately modifying the application state.
+
+📖 Refer to [architecture.md (Layered Application)](./architecture.md#layered-application) to read more about the layered architecture.

+## Visual design best-practices
+
+Add visual clues for clickable items. It should be as clear as possible that they're interactable at first look without hovering. They should also have different visual state when hovering/touching on them that indicates that they are being clicked, which helps with accessibility.

+The decision to not use third-party state management libraries like [`vuex`](https://web.archive.org/web/20230801191617/https://vuex.vuejs.org/) or [`pinia`](https://web.archive.org/web/20230801191743/https://pinia.vuejs.org/) was made to promote code independence and enhance portability.
 
-- [Dialog.vue](./../src/presentation/components/Shared/Dialog.vue) is a shared component that can be used to show modal windows
-- Simply wrap the content inside of its slot and call `.show()` method on its reference.
-- Example:
+Stateful components can mutate and/or react to state changes (e.g., user selection, search queries) in the [ApplicationContext](./../src/application/Context/ApplicationContext.ts). Vue components import [`CollectionState.ts`](./../src/presentation/components/Shared/Hooks/UseCollectionState.ts) to access both the application context and the state.
 
-  ```html
-    <Dialog ref="testDialog">
-      <div>Hello world</div>
-    </Dialog>
-    <div @click="$refs.testDialog.show()">Show dialog</div>
-  ```
+[`UseCollectionState.ts`](./../src/presentation/components/Shared/Hooks/UseCollectionState.ts) provides several functionalities including:
+
+- **Singleton State Instance**: It creates a singleton instance of the state, which is shared across the presentation layer. The singleton instance ensures that there's a single source of truth for the application's state.
+- **State Change Callback and Lifecycle Management**: It offers a mechanism to register callbacks, which will be invoked when the state initializes or mutates. It ensures that components unsubscribe from state events when they are no longer in use or when [ApplicationContext](./../src/application/Context/ApplicationContext.ts) switches the active [collection](./collection-files.md).
+- **State Access and Modification**: It provides functions to read and mutate for accessing and modifying the state, encapsulating the details of these operations.
+- **Event Subscription Lifecycle Management**: Includes an `events` member that simplifies state subscription lifecycle events. This ensures that components unsubscribe from state events when they are no longer in use, or when [ApplicationContext](./../src/application/Context/ApplicationContext.ts) switches the active [collection](./collection-files.md).
+
+📖 Refer to [architecture.md | Application State](./architecture.md#application-state) for an overview of event handling and [application.md | Application State](./presentation.md#application-state) for an in-depth understanding of state management in the application layer.
+
+## Dependency injections
+
+The presentation layer uses Vue's native dependency injection system to increase testability and decouple components.
+
+To add a new dependency:
+
+1. **Define its symbol**: Define an associated symbol for every dependency in [`injectionSymbols.ts`](./../src/presentation/injectionSymbols.ts). Symbols are grouped into:
+   - **Singletons**: Shared across components, instantiated once.
+   - **Transients**: Factories yielding a new instance on every access.
+2. **Provide the dependency**: Modify the [`provideDependencies`](./../src/presentation/bootstrapping/DependencyProvider.ts) function to include the new dependency. [`App.vue`](./../src/presentation/components/App.vue) calls this function within its `setup()` hook to register the dependencies.
+3. **Inject the dependency**: Use Vue's `inject` method alongside the defined symbol to incorporate the dependency into components.
+   - For singletons, invoke the factory method: `inject(symbolKey)()`.
+   - For transients, directly inject: `inject(symbolKey)`.
+
+## Shared UI components
+
+Shared UI components promote consistency and simplifies the creation of the front-end.
+
+In order to maintain portability and easy maintainability, the preference is towards using homegrown components over third-party ones or comprehensive UI frameworks like Quasar.
+
+Shared components include:
+
+- [ModalDialog.vue](./../src/presentation/components/Shared/Modal/ModalDialog.vue) is utilized for rendering modal windows.
+- [TooltipWrapper.vue](./../src/presentation/components/Shared/TooltipWrapper.vue) acts as a wrapper for rendering tooltips.
 
 ## Sass naming convention
 
-- Use lowercase for variables/functions/mixins e.g.
+- Use lowercase for variables/functions/mixins, e.g.:
   - Variable: `$variable: value;`
   - Function: `@function function() {}`
   - Mixin: `@mixin mixin() {}`
-- Use - for a phrase/compound word e.g.
+- Use - for a phrase/compound word, e.g.:
   - Variable: `$some-variable: value;`
   - Function: `@function some-function() {}`
   - Mixin: `@mixin some-mixin() {}`
-- Grouping and name variables from generic to specific e.g.
+- Grouping and name variables from generic to specific, e.g.:
   - ✅ `$border-blue`, `$border-blue-light`, `$border-blue-lightest`, `$border-red`
   - ❌ `$blue-border`, `$light-blue-border`, `$lightest-blue-border`, `$red-border`

 - Use of pipes for writing cleaner code and letting pipes do dirty work.
 
 ## Expressions
 
-- Expressions in the language are defined inside mustaches (double brackets, `{{` and `}}`).
-- Expression syntax is inspired mainly by [Go Templates](https://pkg.go.dev/text/template).
-- Expressions are used in and enabled by functions where they can be used.
+- Expressions start and end with mustaches (double brackets, `{{` and `}}`).
+  - E.g. `Hello {{ $name }} !`
+- Syntax is close to [Go Templates ❤️](https://pkg.go.dev/text/template) but not the same.
+- Functions enables usage of expressions.
   - In script definition parts of a function, see [`Function`](./collection-files.md#Function).
   - When doing a call as argument values, see [`FunctionCall`](./collection-files.md#Function).
+- Expressions inside expressions (nested templates) are supported.
+  - An expression can output another expression that will also be compiled.
+  - E.g. following would compile first [with expression](#with), and then [parameter substitution](#parameter-substitution) in its output.
+

-- A block is defined as `{{ with $parameterName }} Parameter value is {{ . }} here {{ end }}`.
-- The parameters used for `with` condition should be declared as optional, otherwise `with` block becomes redundant.
-- Example:
+Skips its "block" if the variable is absent or empty. Its "block" is between `with` start (`{{ with .. }}`) and end (`{{ end }`}) expressions.
+E.g. `{{ with $parameterName }} Hi, I'm a block! {{ end }}` would only output `Hi, I'm a block!` if `parameterName` has any value..
