### How do I add 3rd party dependencies that are not npm packages?
You can add such dependencies by putting them in `static` directory in the root of your project. The `static` directory will be copied when building the plugin.

### I am getting this message when I run my plugin: `Unable to dynamically transpile ES module A loader plugin needs to be configured via SystemJS.config({ transpiler: 'transpiler-module' }).`
This error occurs when you bundle your plugin using the `grafana-toolkit plugin:dev` task and your code comments include ES2016 code.
There are two issues at play:
* The `grafana-toolkit plugin:dev` task does not remove comments from your bundled package.
* Grafana does not support [ES modules](https://hacks.mozilla.org/2018/03/es-modules-a-cartoon-deep-dive/).
If your comments include ES2016 code, then SystemJS v0.20.19, which Grafana uses internally to load plugins, interprets your code as an ESM and fails.
To fix this error, remove the ES2016 code from your comments.
