First install Node.js and PhantomJS, then create a new js file to load the node-webshot module:

Define options:

Const options = {/ / browser window screenSize: {width: 755, height: 25}, / / document area of the page to be screenshot shotSize: {height: 'all'}, / / Page type siteType:' html'}

Here, the width of the browser window should be set reasonably according to the situation of the web page, the height can be set to a very small value, and then the height of the document area of the page must be set to all, and the width defaults to the width of the window, so that you can take a complete screenshot of the table with the smallest size.

Next, define the html string:

Let html = "target rich text html code, eg:..."

Note that the HTML code must remove the newline character and replace the double quotation marks with single quotation marks.

Finally, take a screenshot:

Webshot (html, 'demo.png', options, (err) = > {if (err) console.log (`Webshot error: ${err.message} `);}); that's all for "how WeChat Mini Programs interprets web content". Thank you for reading.
