editorjs-parser is a NPM package for parsing the output object of EditorJs to HTML.
This is a fork of the original package and has the following changes:
- Support for more classes for blocks (so you can set a class for every element - useful for frameworks live tailwindcss)
- Support for more blocks (eg. checklist)
Only supported by the original package.
Use the package manager npm to install editorjs-parser.
npm install --save @SCNetwork/editorjs-parserTo use the package in a browser, import Browser version through CDN to your HTML file and just call edjsParser class:
const parser = new edjsParser(config, customParsers, embedMarkup);To import the package in Node and Front-end code:
const edjsParser = require("editorjs-parser");
const parser = new edjsParser(config, customParsers, embedMarkup);NOTE: Parameters are optional. If you want to only pass the second parameter, set the first parameter to undefined.
To parse all blocks, pass the exact EditorJs' output object:
const markup = parser.parse(output);To parse one block, pass a complete block:
const markup = parser.parseBlock(block);NOTE: HTML markup in code blocks are already sanitized and ready to be sent to browser. You don't have to do anything.
NOTE: Code blocks are compatible with highlight.js

Warning (you may need to style that yourself)
NOTE: It is pointless to use both
imageandsimple-imageblock types in the same editor instance, but this parser supports both of them, and you can use any of them that fulfills your needs.
If you have a custom block like so:
{
type: "customBlock",
data: {
// Your data
}
}You can pass an object of custom parsers or override existing parsers of supported blocks as the second argument, like so:
const customParsers = {
customBlock: function(data, config) {
// parsing functionality
// the config arg is user provided config merged with default config
},
image: function(data, config): {
return `<img src="${data.file.url}" alt="${data.caption}" >`;
}
}
const parser = new edjsParser(undefined, customParsers);NOTE: The config arg is user provided config merged with default configuration.
This is the default configuration. You can override any of these properties by passing a config object.
{
image: {
use: "figure", // figure or img (figcaption will be used for caption of figure)
imgClass: "img",
figureClass: "fig-img",
figCapClass: "fig-cap",

},
paragraph: {
pClass: "paragraph",
},
header: {
1: {
hClass: "header1"
},
2: {
hClass: "header2"
},
3: {
hClass: "header3"
},
4: {
hClass: "header4"
},
5: {
hClass: "header5"
},
6: {
hClass: "header6"
}
},
warning: {
containerClass: "warning",
titleClass: "warningTitle",
messageClass: "messageClass"
},
checklist: {
itemClass: "checklistItem",
checkBoxClass: "checkBox",
contentClass: "checklistContent",
containerClass: "CheckboxContainer"
},
delimiter: {
element: 'br', // Element of the delimeter, supports every element (eg. br, hr, p, h1)
class: 'delimiter',
content: null // Only availble if the selected element can contain a value
},
list: {
"ol": {
listClass: "ol-list",
listItemClass: "ol-list-item"
},
"ul": {
listClass: "ol-list",
listItemClass: "ol-list-item"
}
},
code: {
codeBlockClass: "code-block",
},
embed: {
useProvidedLength: false,
// set to true if you want the returned width and height of editorjs to be applied
// NOTE: sometimes source site overrides the lengths so it does not work 100%
},
quote: {
applyAlignment: false,
// if set to true blockquote element will have text-align css property set
quoteClass: "quote",
pClass: "pQuote",
citeClass: "cite"
},
table: {
trClass: "tr",
tableClass: "table",
tbodyClass: "tbody",
tdClass: "td"
}
};To use the relative path, you should return the filename of the uploaded image from your backend, alongside the url (for more info docs).
Then include the property name of filename in config like so: (for example the property name of the returned filename is imageFileName)
const config = {
image: {
path: "/img/<imageFileName>";
}
};
const parser = new edjsParser(config);NOTE: Images will have class img.
NOTE: If the image is stretched, the parsed img tag will have img-fullwidth as class.
NOTE: If image is set to have a border, the parsed img tag will have img-border as class.
NOTE: If withBackground is set to true, the parsed img tag will have img-bg as class.
You can style, according to these classes.
If you want the returned width and height of embedded element to be applied, set useProvidedLength option to true in the config:
const config = {
embed: {
useProvidedLength: true,
},
};
const parser = new edjsParser(config);If you want to render a custom markup for your embed service, pass it in an object in third argument. For example if you want your own markup to be rendered for Youtube video embed, you got to do this:
const parser = new edjsParser(undifined, undifined, {
youtube: `Your markup in string`,
});You also have access to data object. To use that you should put variable names in placeholders, like so:
const customEmbeds = {
youtube: `<iframe src="<%data.embed%>" width="<%data.width%>"><%data.caption%></iframe>`,
};
const parser = new edjsParser(undifined, undifined, customEmbeds);NOTE: If you want to have useProvidedLength functionality, use <%data.length%> instead of <%data.width%> and <%data.height%> in embed markups.
<%data.length%> returns string like this: width="300" height="500"
If you need the returned alignment of blockquotes to be set, set applyAlignment to true in the config:
const config = {
quote: {
applyAlignment: true;
}
};
