How to use data attributes in React without using quotes (quotes in this case make code less readable)?

const e = React.createElement;

e(
  "span", {
    id: "foo",
    className: "bar",
    "data-tippy-content": "tooltip",
  }, "Foobar"),

... and without using JSX.

    You can't. Object keys must be either quoted or valid JS identifiers. data-tippy-content is a subtraction, as far as JS is concerned. Commented Jun 16, 2019 at 7:42
  • I was hoping something like dataSet was available. github.com/facebook/react/issues/1259 Commented Jun 16, 2019 at 7:50

Since you're already not using JSX, you could write a wrapper for React.createElement that transforms dataset: {...} into data- attributes:

const e = (tag, attrs, children) => {
  const { dataset, ...otherAttrs } = attrs;
  if (dataset) {
    for (const key in dataset) {
      otherAttrs[`data-${key}`] = dataset[key];
    }
  }
  return React.createElement(tag, otherAttrs, children);
};

e("h1", {dataset: {"tippy-content": "foo"}}, ...);
