 The following developer guide rules are specific for working with the React framework.
 
-#### Prefer reactDirective over react-component
-
-When using `ngReact` to embed your react components inside Angular HTML, prefer the
-`reactDirective` service over the `react-component` directive.
-You can read more about these two ngReact methods [here](https://github.com/ngReact/ngReact#features).
-
-Using `react-component` means adding a bunch of components into angular, while `reactDirective` keeps them isolated, and is also a more succinct syntax.
-
-**Good:**
-
-```html
-<hello-component
-  fname="person.fname"
-  lname="person.lname"
-  watch-depth="reference"
-></hello-component>
-```
-
-**Bad:**
-
-```html
-<react-component name="HelloComponent" props="person" watch-depth="reference" />
-```
-
 #### Name action functions and prop functions appropriately
 
 Name action functions in the form of a strong verb and passed properties in the form of on<Subject><Change>. E.g:

 - Use `i18n.translate()` in NodeJS or any other framework agnostic code, where `i18n` is the I18n engine from `@osd/i18n` package.

-
-AngularJS wrapper has 4 entities: translation `provider`, `service`, `directive`
-and `filter`. Both the directive and the filter use the translation `service`
-with i18n engine under the hood.
-
-The translation `provider` is used for `service` configuration and
-has the following methods:
-- `addMessages(messages: Map<string, string>, [locale: string])` - provides a way to register
-translations with the library
-- `setLocale(locale: string)` - tells the library which language to use by given
-language key
-- `getLocale()` - returns the current locale
-- `setDefaultLocale(locale: string)` - tells the library which language to fallback
-when missing translations
-- `getDefaultLocale()` - returns the default locale
-- `setFormats(formats: object)` - supplies a set of options to the underlying formatter
-- `getFormats()` - returns current formats
-- `getRegisteredLocales()` - returns array of locales having translations
-- `init(messages: Map<string, string>)` - initializes the engine
-
-The translation `service` provides only one method:
-- `i18n(id: string, { values: object, defaultMessage: string, description: string })` –
-translate message by id
-
-The translation `filter` is used for attributes translation and has
-the following syntax:
-```
-{{ ::'translationId' | i18n: { values: object, defaultMessage: string, description: string } }}
-```
-
-Where:
-- `translationId` - translation id to be translated
-- `values` - values to pass into translation
-- `defaultMessage` - will be used unless translation was successful (the final
-  fallback in english, will be used for generating `en.json`)
-- `description` - optional context comment that will be extracted by i18n tools
-and added as a comment next to translation message at `defaultMessages.json`
-
-The translation `directive` has the following syntax:
-```html
-<ANY
-  i18n-id="{string}"
-  i18n-default-message="{string}"
-  [i18n-values="{object}"]
-  [i18n-description="{string}"]
-></ANY>
-```
-
-Where:
-- `i18n-id` - translation id to be translated
-- `i18n-default-message` - will be used unless translation was successful
-- `i18n-values` - values to pass into translation
-- `i18n-description` - optional context comment that will be extracted by i18n tools
-and added as a comment next to translation message at `defaultMessages.json`
-
-If HTML rendering in `i18n-values` is required then value key in `i18n-values` object
-should have `html_` prefix. Otherwise the value will be inserted to the message without
-HTML rendering.\
-Example:
-```html
-<p
-  i18n-id="namespace.id"
-  i18n-default-message="Text with an emphasized {text}."
-  i18n-values="{
-    html_text: '<em>text</em>',
-  }"
-></p>
-```
-
-Angular `I18n` module is placed into `autoload` module, so it will be
-loaded automatically. After that we can use i18n directive in Angular templates:
-```html
-<span
-  i18n-id="welcome"
-  i18n-default-message="Hello!"
-></span>
-```
-
-In order to translate attributes in AngularJS we should use `i18nFilter`:
-```html
-<input
-  type="text"
-  placeholder="{{ ::'osd.management.objects.searchAriaLabel' | i18n: {
-    defaultMessage: 'Search { title } Object',
-    values: { title }
-  } }}"
->
-```

 ### Description
 
-The tool is used to extract default messages from all `*.{js, ts, jsx, tsx, html }` files in provided plugins directories to a JSON file.
+The tool is used to extract default messages from all `*.{js, ts, jsx, tsx }` files in provided plugins directories to a JSON file.
 
 It uses Babel to parse code and build an AST for each file or a single JS expression if whole file parsing is impossible. The tool is able to validate, extract and match IDs, default messages and descriptions only if they are defined statically and together, otherwise it will fail with detailed explanation. That means one can't define ID in one place and default message in another, or use function call to dynamically create default message etc.
