@hiveio/content-renderer

Portable library that renders Hive posts and comments to string. It supports markdown and html and mimics the behaviour of condenser frontend.

Features:

• supports markdown and html

• sanitizes html and protects from XSS

Credit: this library is based on the code from condenser. It's aim is to allow other projects display Hive content the right way without porting the same code over and over.

Server side usage

Installation:

$ npm install --save @hiveio/content-renderer

Typescript:

import { DefaultRenderer } from "@hiveio/content-renderer";

const renderer = new DefaultRenderer({
    baseUrl: "https://hive.blog/",
    breaks: true,
    skipSanitization: false,
    allowInsecureScriptTags: false,
    addNofollowToLinks: true,
    doNotShowImages: false,
    ipfsPrefix: "",
    assetsWidth: 640,
    assetsHeight: 480,
    imageProxyFn: (url: string) => url,
    usertagUrlFn: (account: string) => "/@" + account,
    hashtagUrlFn: (hashtag: string) => "/trending/" + hashtag,
    isLinkSafeFn: (url: string) => true,
});

const safeHtmlStr = renderer.render(postContent);
