Example app, how to include Frappe Charts in a public frappe page.

bench get-app https://github.com/alyf-de/frappe_charts_example.git
bench install-app frappe_charts
bench setup requirements
bench build --app frappe_charts

Please check the following files:

• frappe_charts/public/js/frappe_charts.js
• frappe_charts/public/build.json
• frappe_charts/www/index.html
• frappe_charts/www/index.js
• frappe_charts/hooks.py

Frappe Charts was installed via NPM (you don't need to run this again for this app):

cd ~/frappe-bench/apps/frappe_charts
npm init
npm i -P frappe-charts

This way it got added to package.json and will be added automatically when the app gets installed.

Then, in frappe_charts/public/js/frappe_charts.js we import the code from the NPM package and store it in frappe.Chart:

import { Chart } from 'frappe-charts/dist/frappe-charts.esm.js'

frappe.Chart = Chart;

In frappe_charts/public/build.json we define to build the above file into js/frappe_charts.min.js. This step creates a new file frappe_charts.min.js that includes the definition of Chart and our own code from above. In frappe_charts/public a symbolic link to the app's node_modules folder gets created at the time of the build. This way we can include frappe charts' css from the node_modules folder in build.json.

The resulting files from the build will be stored in the assets/js/ folder on runtime.

In frappe_charts/hooks.py we define to serve assets/js/frappe_charts.min.js with every public page:

# include js, css files in header of web template
web_include_css = "assets/css/frappe_charts.min.css"
web_include_js = "assets/js/frappe_charts.min.js"

Now we can use frappe.Chart() in any public page, like frappe_charts/www/index.html.
