# Create Template

> Create a new template with optional variables.

export const ResendParamField = ({children, body, path, ...props}) => {
  const [lang, setLang] = useState(() => {
    return localStorage.getItem('code') || '"Node.js"';
  });
  useEffect(() => {
    const onStorage = event => {
      const key = event.detail.key;
      if (key === 'code') {
        setLang(event.detail.value);
      }
    };
    document.addEventListener('mintlify-localstorage', onStorage);
    return () => {
      document.removeEventListener('mintlify-localstorage', onStorage);
    };
  }, []);
  const toCamelCase = str => typeof str === 'string' ? str.replace(/[_-](\w)/g, (_, c) => c.toUpperCase()) : str;
  const resolvedBody = useMemo(() => {
    const value = JSON.parse(lang);
    return value === 'Node.js' ? toCamelCase(body) : body;
  }, [body, lang]);
  const resolvedPath = useMemo(() => {

  }, [path, lang]);
  return <ParamField body={resolvedBody} path={resolvedPath} {...props}>
      {children}
    </ParamField>;
};

## Body Parameters

  The HTML version of the template.
</ParamField>

<ParamField body="alias" type="string">

</ParamField>

<ParamField body="from" type="string">
  Sender email address.

  This value can be overridden when sending an email using the template.
</ResendParamField>

<ParamField body="text" type="string">
  The plain text version of the message.

  <Info>
    If not provided, the HTML will be used to generate a plain text version. You can opt out of this behavior by setting value to an empty string.
  </Info>
</ParamField>

<ParamField body="react" type="React.ReactNode">
  The React component used to write the template. *Only available in the Node.js
  SDK.*
</ParamField>

<ParamField body="variables" type="array">
  The array of variables used in the template. Each template may contain up to 50 variables.

  Each variable is an object with the following properties:

  <Expandable defaultOpen title="properties">
    <ParamField body="key" type="string" required>
      The key of the variable. We recommend capitalizing the key (e.g. `PRODUCT_NAME`). The following variable names are reserved and cannot be used:
      `FIRST_NAME`, `LAST_NAME`, `EMAIL`, `RESEND_UNSUBSCRIBE_URL`, `contact`, and `this`.
    </ParamField>

    <ParamField body="type" type="'string' | 'number'" required>
      The type of the variable.

      Can be `'string'` or `'number'`
    </ParamField>

    <ResendParamField body="fallback_value" type="string | number">
      The fallback value of the variable. The value must match the type of the variable.

      If no fallback value is provided, you must provide a value for the variable when sending an email using the template.
    </ResendParamField>
  </Expandable>

  <Info>
    Before you can use a template, you must publish it first. To publish a
    template, use the [Templates dashboard](https://resend.com/templates) or
    [publish template API](/api-reference/templates/publish-template).
