Using nunjucks, how can I define some global variables that should always be available within all templates?
Ideally, they would be specified somewhere in the enviro
I was just looking for this and came here. Looks like there's now a recommended way which was added in recently in version 1.0.6.
See Environment.addGlobal.
It might be also helpfull for someone. It is possible to avoid writing any js code when dealing with global variables in nunjucks.
You need to create a _globals.html file, which contains all the global variables.
{% set some_var1 = "Foo" %}
{% set some_var2 = "Bar" %}
Then include _globals.html to any page, where you need the global variable. E.g. somePage.html
{% import '_globals.html' as globals %}
<span>{{globals.some_var1 }}</span>
<span>{{globals.some_var2 }}</span>
For more info please check http://mozilla.github.io/nunjucks/templating.html#set
It's not documented (or perhaps advised), but this works:
var njglobals = require('nunjucks/src/globals');
njglobals.someVar = 'someValue';
You can now use someVar
in your templates.
Be sure not to overwrite any of the existing properties of the njglobals
object, though (for nunjucks@1.0.1
, they are range
, cycler
and joiner
).
