API: TypeScript (pure) (r1)

This API supports TypeScript in the browser. The World is pure TypeScript.

This API enables pure TypeScript editing by setting up a few things for you. If you do not like that, use the TypeScript API to get full control of the page.

This API works as follows:

• The World is a web page with HTML elements.
• The code is pure TypeScript.
• The API includes the latest typescript.js.
• At run-time the TypeScript code is compiled using ts.transpile and run.
• The TypeScript code is syntax highlighted. It is not syntax checked. We do not have TypeScript syntax checking yet.

This API has further features:

• Obfuscation is disabled. We do not have TypeScript obfuscation yet.
• Includes jQuery 3.6.0.
• The API sets a blank page and sets a page title.
• There is no run header.
• You reload and close the page like any other tab.
• Links on the page open in the same window (not in a new window like in the canvas APIs).
• The API loads up minimal CSS that should not conflict with user CSS.
• The style of the blank page is a body with margin 0 and padding 0. You can change it using JS like this:

   
    $('body').css( "margin", "20px" );
    $('body').css( "padding", "20px" );
  

Screenshots:

• The screenshot does not assume there is a canvas. Instead it takes a screenshot of the HTML.
• It uses the html2canvas library to build a screenshot of your page using JS.
• The html2canvas library has some limitations and may not be able to accurately screenshot your page.

• The basic design of this site is for .js files. For TypeScript, we leave the underlying file type as .js (not .ts). It does not matter and you will not normally notice.

TypeScript only code. The API will compile it and run it.
