How to access flask config in javascript?

Question

I need the config variables in javascript in my flask application. Currently, I access the config variables via:

@app.route(\'/api/getconfigs/\')
def get_con

You could load the specific variable into your jinja2 globals like so:

app.jinja_env.globals.update(VARIABLENAME=config['VARIABLENAME'])

Then in an always included base-template load the variable into your javascript like so.

Or just throw the whole config into your jinja2 env like so:

app.jinja_env.globals.update(config=app.config)

And then insert the specific Variable only if it is found in config.

{% if config['VARIABLENAME'] %}
     
{% endif %}
