truncate html by text length
using npm.
npm install -S trunc-html
trunc(html, limit, options?)Returns the result of truncating the provided html. A plain-text version is provided as well.
var html = 'the force is <strong>with this one</strong>. some more rubbish';
trunc(html, 30);
// <-
// { html: 'the force is <strong>with this one</strong>. …',
// text: 'the force is with this one. …' }
limitMaximum amount of text characters allowed. When the limit is reached, the algorithm will trace back to the last word separator and trim the rest into a … glyph.
options.ignoreTagsIf you'd like to supress certain HTML tags from being output you can provide an array of tags to be excluded, set ignoreTags to something like ['strong'].
options.imageAltTextIf you'd like to use the alt attribute for the text portion of the result, instead of dropping images entirely in text flavor, set imageAltText to true.
options.sanitizerOptions passed to insane. Note that these options are overridden by the options provided by trunc-html, so you can't use transformText, which trunc-html reserves for itself.
