How to make Bokeh work with a REST api backend instead of bokeh-serve?

问题

How can I make Bokeh work with my own REST api backend using CustomJS instead of bokeh-serve? components() do not seem to render inputs and inputs seem to come always with a need to run bokeh-serve.

Barnabas, it is basically impossible to diagnose a problem if you do not provide actual code and describe in extreme detail what you have already tried. FWIW here is a minimal script that renders a Bokeh Button in a Flask app:

import flask

from bokeh.embed import components
from bokeh.core.templates import FILE
from bokeh.models.widgets import Button
from bokeh.resources import INLINE
from bokeh.util.string import encode_utf8

app = flask.Flask(__name__)

@app.route("/")
def foo():
    button = Button(label="test")

    script, div = components(button, INLINE)
    html = FILE.render(
        plot_script=script,
        plot_div=div,
        bokeh_js=INLINE.render_js(),
        bokeh_css=INLINE.render_css(),
    )
    return encode_utf8(html)

app.run(debug=True)

There are things I'd certainly do different in a real deployment (no INLINE resources, e.g) but without additional information about your actual use-case or what you are really wanting to do it is impossible to offer additional guidance.

It turns out that to use widgets one needs to include extra js and css to the html page.
In my case those are

bokeh-0.11.1.min.js,
bokeh-widgets-0.11.1.min.js
bokeh-compiler-0.11.1.min.js and
bokeh-widgets-0.11.1.min.css.
