Edit Article

Details

The articles actions for posting end editing articles had to be updated to work with comments and articles:

//post to blockchain
if (isComment) {
  //generate unique permalink for new comment
  const newPermLink = getUniquePermalinkComment(parentPermlink);
  await api.comment(parentAuthor, parentPermlink, store.user.username, newPermLink, '', body, {});
} else {
  //generate unique permalink for new article
  const newPermLink = getUniquePermalink(title);
  await api.comment('', tags[0], store.user.username, newPermLink, title, body, {tags: tags});

  //successfully posted to blockchain, now posting to backend with permalink and category
  await apiPost('/posts/create', {
    author: store.user.username,
    permlink: newPermLink,
    access_token: store.user.accessToken,
    category: tags[1],
    tags: tags
  });
}

(actions/articles.js - postArticle)

The editArticle function is similar, comments do not need call to the backend API of KnackSteem because they only get stored in the blockchain and an API call to the backend gets the comments with SteemConnect - server side.
Side note: Posting and editing comments needs an empty object for the last parameter (JSON Metadata).

The Editor component is in use for new contributions, editing contributions, new comments (replies) and editing comments now. One component to rule them all :)
Several properties have been added to make the component versatile, including some code comments to make it clear what they are being used for. Different functions are being called when the user clicks on the button for posting/updating (it will be a different label depending on the operation). And if there is a callback function (as React prop), it will get called right after the editing or posting happened:

if (isEdit) {
  await dispatch(editArticle(title, value.toString('markdown'), tags, articleData, isComment, parentPermlink, parentAuthor));
} else {
  await dispatch(postArticle(title, value.toString('markdown'), tags, isComment, parentPermlink, parentAuthor));
}
if (onDone) {
  onDone();
}

(components/Editor/index.js)

Editing and posting are similar to some extend, so we may be able to combine them later. I wanted to keep them separate for now though, just in case there´s more to be added. It is a different operation after all.
Side Note: Parent permalink and author name are always needed for posting and editing comments in the blockchain, so I had to add those as props as well. It could just be included in the comment response of the backend later though, that would reduce some code in the frontend.

Configuration for the SteemConnect callback can be found in the main config file. It depended on the dev/prod flag earlier, this PR changes it to an URL that should always be correct - no matter if it´s the dev build or the prod build:

//general configuration for the app
export default {
  SteemConnect: {
    scope: ['login', 'custom_json', 'claim_reward_balance', 'vote', 'comment', 'delete_comment'],
    callbackURL: `${window.location.origin}/callback`
  }
};

(config.js)

The article detail page and the component for a single comment have new state variables and callback functions for activating the editor for editing and replying:

onEditClick = () => {
  this.setState({
    isEditMode: true
  });
};
onReplyClick = () => {
  this.setState({
    isReplyMode: true
  });
};
onCancelEditorClick = () => {
  this.setState({
    isEditMode: false,
    isReplyMode: false
  });
};
onDoneEditorClick = () => {
  this.setState({
    isEditMode: false,
    isReplyMode: false,
    isLoading: true
  });
  //reload after update
  this.getArticle();
};

(containers/ArticleDetail/index.js)

For example, a click on the reply link only sets the state variable isReplyModeto true. The rest is taken care of by React in the render function with conditional rendering:

{isReplyMode && <Editor isEdit={false} isComment={true} onCancel={this.onCancelEditorClick} onDone={this.onDoneEditorClick} parentPermlink={data.permlink} parentAuthor={data.author} />}

(containers/ArticleDetail/index.js)

Generating the permalink for comments works in a different way, so i had to add a separate function for that. It takes the parent permalink and adds a re- at the beginning and a random string at the end:

//generate unique permalink for comments
export const getUniquePermalinkComment = (permlink) => {
  return `re-${permlink}-${Math.random().toString(36).substr(2, 16)}`;
};

(services/functions.js)
