| ## Use `npm` to get our dependencies in the right place | |||
| `htmlwidgets` load dependencies in a way that's exactly the same as using a | |||
| `<script>` tag in the HTML `<head>`. | |||
| Look at the documentation on Frappe Charts and decide which file we should use. | |||
| Here's the block from their docs | |||
| ``` | |||
| <script src="https://cdn.jsdelivr.net/npm/frappe-charts@1.2.4/dist/frappe-charts.min.iife.js"></script> | |||
| <!-- or --> | |||
| <script src="https://unpkg.com/frappe-charts@1.2.4/dist/frappe-charts.min.iife.js"></script> | |||
| ``` | |||
| We need to get our dependecy into a subfolder of `inst/htmlwidgets`. | |||
| Convention is `inst/htmlwidgets/lib/<dependency_name>`. | |||
| Rather than creating the directoy and copying over, etc., | |||
| we can have an `npm` build script do this for us. | |||
| To avoid issues with mac/windows, | |||
| we'll add a dev dependency on [`cpy-cli`](https://github.com/sindresorhus/cpy-cli) | |||
| ```bash | |||
| npm install cpy-cli --save-dev | |||
| ``` | |||
| and | |||
| ```{r create-lib-dir} | |||
| dir.create("inst/htmlwidets/lib/frappe-charts", recursive = TRUE) | |||
| ``` | |||
| and then edit `package.json` to add copy tasks | |||
| ``` | |||
| "scripts": { | |||
| "copy-js": "cpy 'node_modules/frappe-charts/dist/frappe-charts.min.iife*' inst/htmlwidgets/lib/frappe-charts/", | |||
| "build": "npm run copy-js" | |||
