1.2. Documentation

Here will explain the API provided by our app that can be found under the globally defined namespace NagwaHTMLEditor.

1.2.1. Component Library API

A react component is exposed and exported as default that renders the Editor component.

type Locale = "ar/eg" | "en/eg"

type UploadType = "image" | "audio" | "attachment"
type UploadFunction = (file: File) => Promise<string>
type UploadProps = { storeUrl?: string; uploadFn?: UploadFunction; limit?: number; accept?: string[] }
type UploadConfig = string | UploadFunction | UploadProps

type Feature =
  | "marks" // bold, italic, underlined, and strikethrough marks
  | "color" // text color
  | "scriptEffects" // sub script and super script
  | "alignment"
  | "directions"

}

export const NagwaHTMLEditor: React.VFC<Props> = () => {...}
export default NagwaHTMLEditor

1.2.2. Component Library API Explanation

NagwaHTMLEditor: This is the main component to be used to render an instance of the Editor and keep its state in memory. This component is exported namely and as default so that you can use the NagwaHTMLEditor name when importing or use any other name needed in your case. This is a void react component that accepts some props as follows:
- uniqueKey: This key is required and has to be unique because it stores the different editors states in an object with this uniqueKey. If it was not provided (not recommended) it will fallback to a randomly generated key so that you won't need to add a uniqueKey when you need to render only one Editor, if there's more than one please provide a uniqueKey.
- locale: The locale of the provided oldValue to set the direction of the element according to it. This property is optional and falls back to "en/eg" if not provided.
- oldValue: The old HTML value to initiate the app with. This is an optional property, if not provided the app will start with an empty state.
- uploadImage: Can be a function that handles uploading the image inputted by the user, a string url that represents a file storage or hosting service that contains images to be called by ID, or an object containing both properties, and extra. This property is optional, if not provided the feature of inserting images will not be available.
- uploadAudio: Can be a function that handles uploading the audio inputted or recorded by the user, a string url that represents a file storage or hosting service that contains audios to be called by ID, or an object containing both properties, and extra. This property is optional, if not provided the feature of inserting audios will not be available.
- uploadAttachment: Can be a function that handles uploading the file attached by the user or an object containing the function, and extra. This property is optional, if not provided the feature of attaching files will not be available.
- hideToolbarOnBlur: If this property was passed as true the toolbar will be hidden until the editor is focused. The default value is false which will make the toolbar visible at all times.
- include: An array of feature string to include these features in the editor. By default, all features are included.
- exclude: An array of feature string to exclude from the editor. By default, no feature is excluded. If both include and exclude arrays are present, the exclude array will me omitted, and only the features in the include array will be included.
- onInit: A callback function that will fire once the editor is initialized. An optional editorAPI can be expected as an argument to the function.
- onChange:A callback function that will fire with every update of the editor's value. An optional string value (the new editor's value) can be expected as an argument to the function.
- onAttachmentClick: A callback function that will fire when an attachment row is clicked. An optional attachment object and an optional index can be expected as arguments to the function. This property defaults to a function that will download the attachment when clicked. If set to null, Nothing will happen when clicking the attachment.
- autoFocus: A boolean that indicates whether or not to focus the editor if it is initialized. Defaults to false.
- toolbarStyles: A CSSProperties (styles) object that can be passed to apply styles to the toolbar.
- textareaStyles: A CSSProperties (styles) object that can be passed to apply styles to the editor's textarea.

Aside from the exported component the API extraction and deletion is implementing the following functions that are namely exported.

interface EditorAPI {
  editor: CustomEditor // The slate Editor API
  getValue: (includeAttachments = true) => string
  getDeserializedValueWithoutAttachments: () => Descendant[]
  getAttachmentsValue: () => string
  getDeserializedAttachments: () => AttachmentObj
  setValue: (oldValue: string, { locale?: "ar/eg" | "en/eg"; includeAttachments: boolean } = { includeAttachments: true }) => void
  setDeserializedValue: (oldValue: Descendant[], shouldDeleteAttachments = true) => void
  setAttachments: (oldValue: string | AttachmentObj[]) => void
  clear: (shouldDeleteAttachments = true) => void
  readonly isEmpty: boolean
}

function getEditorAPI(uniqueKey: string): EditorAPI // The same Static API interface (See the below section)
function deleteEditorAPI(uniqueKey: string): boolean

EditorAPI:
- editor: The slate editor itself
- getValue: This method serializes the current editor value state into the desired HTML output. It takes an optional parameter includeAttachments. If set to true, the attachments value will be serialized also. It defaults to true.
- getDeserializedValueWithoutAttachments: This method returns the current state of the corresponding editor, without the attachments part. The state matches the structure mentioned in the @types folder.
- getAttachmentsValue: This method serializes the attachments and returns its string value.
- getDeserializedAttachments: This method returns the current state of attachment array. The state matches the structure mentioned in the @types folder.
- setValue: This method deserializes the HTML string inputted and sets the editor's state to the deserialized value. It takes an optional options object with the following properties:
  - includeAttachments: If set to true, the attachments value will be set also, else, the textarea value will be set only, and the attachments will remain the same. It defaults to true.
  - locale: "ar/eg" or "en/eg"
- setDeserializedValue: Sets the editor's current value from slates Descendant object array. It takes an optional parameter shouldDeleteAttachments that defaults to true. If true, will delete current attachments
- setAttachments: Takes an attachments HTML markup string, or an array of attachment object, and sets the attachments.
- deleteAttachments: Deletes current attachments
- clear: This method clears the current editor value state and empties the editable area. It takes an optional parameter shouldDeleteAttachments that defaults to true. If true, will delete current attachments
- isEmpty: This is a read-only property that tells you if the current state of the editor is empty or not.
getEditorAPI: A function that accesses the store with the uniqueKey and returns the corresponding EditorAPI for this editor instance. Notice that this uniqueKey should be the same one as the one provided for the NagwaHTMLEditor component.
This function is only namely exported.
deleteEditorAPI: A function that accesses the store with the uniqueKey and deletes the corresponding EditorAPI for this editor instance. Notice that this uniqueKey should be the same one as the one provided for the NagwaHTMLEditor component.
This function is only namely exported.

1.2.3. Static API Interface

The Static library uses the same API as the component library with some differences.

type Descendant = CustomElement | CustomText

type StaticHTMLEditorProps = HTMLEditorProps & { containerId: string }

class NagwaHTMLEditor {
  public static init: (config: StaticHTMLEditorProps) => EditorAPI
}

1.2.4. Static API Explanation

The static library API uses the same API of the Component API's Interface with few different exported items.

NagwaHTMLEditor:
- init: The main method that initiates the app with the desired config and returns EditorAPI object with utility methods.
EditorConfig:
- containerId: The id of the HTML element to contain the app. Note that the element corresponding with the provided id will be replaced with a div element with the same provided id. This property is mandatory for the app to run, if not provided the app won't run.

1.3. Editor Output Samples

Here are some editor output samples that you can get using the getValue method:

      })
      const stemEditorValue = stemEditor.getValue()

1.4.2. Using the Component Library API

Here's an example of how to consume the Component Library API.
After installing the library (see: Install Component Library Using NPM), in your react app import the editor and the needed functions from the library as follows:

import { FC, useEffect } from "react"
import NagwaHTMLEditor, { getEditorAPI } from "nagwa-html-editor"

const uniqueKey = "******" //make sure it's unique for every editor instance

const Component:FC = () => {

  useEffect(() => {
    const editorAPI = getEditorAPI(uniqueKey)
    console.log(editorAPI)
  })

  return <NagwaHTMLEditor uniqueKey={uniqueKey} />
}

2. Forking Guide

These instructions will get you a copy of the project up and running on your local machine.

2.1. Prerequisites

You have to have Node.js v14.18.1, and npm v6.14.15 installed.
Also, check ./package.json for all the packages used in this project

2.2. Installing

Clone this repo, open the terminal and navigate to the repo directory on your local machine, and then run:

npm install

wait until it's done and you're good to go!

Note: if installation fails because if npm, make sure you're using v16. if it still fails, install using v14, then re-install using v16.

Note: There will be a high severity audit problem when you install the packages.
This Problem is caused by react-scripts package.
This is a false positive according to #9469 (comment) from the maintainers on this issue, so there's nothing to worry about.

3. Built With

TypeScript - The main language used.
Node.js v16 - The run-time environment used to run and build the app (Currently working using v16).
React - The web framework used.
Slate - The library used to create the text editor.

4. Main Features

Inserting any type of text.
Making text bold.
Making text italic.

5. Git Style

5.1. Message Structure

A commit messages consists of three distinct parts separated by a blank line: the title, an optional body and an optional footer. The layout looks like this:

type: subject

body

5.1.1. The Type

The type is contained within the title and can be one of these types:

feat: a new feature
fix: a bug fix
docs: changes to documentation
style: formatting, missing semi colons, etc; no code change
refactor: refactoring production code
test: adding tests, refactoring test; no production code change
chore: updating build tasks, package manager configs, etc; no production code change

5.1.2. The Subject

Subjects should be no greater than 50 characters, should begin with a capital letter and do not end with a period.

Use an imperative tone to describe what a commit does, rather than what it did. For example, use change; not changed or changes.

5.1.3. The Body

Not all commits are complex enough to warrant a body, therefore it is optional and only used when a commit requires a bit of explanation and context. Use the body to explain the what and why of a commit, not the how.

When writing a body, the blank line between the title and the body is required and you should limit the length of each line to no more than 72 characters.
