Is there a way to set data dynamically ?

[gterras]

Hi,

Thanks for the nice plugin. I was wondering if there was a way to inject dynamic data to the template? Right now having to use a predefined config file make it really difficult (unless I'm missing something).

.nunjucksrc

{
    root: ".",
    data: { foo : "bar"}
} 

What if I want to inject a foo2 prop inside a specific template ? This is working :

index.html.njk

...
{% set foo2 = 'bar2' %}
{{ foo2 }} 

but this is not :
index.html.njk

...
{% set foo2 = 'bar2' %}
<script src="./script.js.njk" ></script>

script.js.njk
{{ foo2 }} // Output nothing

The only solution I am considering right now is to fs.writeFile the .nunjucksrc, is there better to do ?

Thank you !

.nunjucksrc is for static data (JSON). If you want dynamic data, you'll need to use a JS file, e.g.:

$ cat nunjucks.config.js

module.exports = {
    data ({ filename }) {
        if (filename === 'script.js.njk') {
            return { foo2: 'whatever' }
        } else {
            return { foo: 'bar' }
        }
    }
}
