    build status

    This is a TypeScript AST Transformer that can speed up reconciliation and reduce garbage collection pressure by hoisting React elements to the highest possible scope, preventing multiple unnecessary reinstantiations, similar to babel-plugin-transform-react-constant-elements.

    Example:

    const Hr = () => {
      return <hr className="hr" />;
    };
     
    // becomes 
    const _ref = <hr className="hr" />;
     
    const Hr = () => {
      return _ref;
    };

    This is especially useful for hoisting static but expensive content such as SVG.

    Usage

    First of all, you need some level of familiarity with the TypeScript Compiler API.

    compile.ts & tests should have examples of how this works. The available options are:

    verbose?: boolean

    Enabling this will allow this transformer to log out which nodes are hoisted.
