Need to use babel and preact-compat?

.babelrc

{
  "plugins": [
    ["transform-react-jsx", { "pragma":"h" }],
    ["module-resolver", {
      "root": ["."],
      "alias": {
        "react": "preact-compat",
        "react-dom": "preact-compat"
      }
    }]
  ],
  "presets": [
    ["es2015"],
    "react"
  ],
}
