Precompile nunjucks templates using Webpack 4












1














Moving from Gulp to Webpack (it's a Backbone.js app). I need to precompile all the *.html files (nunjucks templates) & concat into a single js file (e.g. template.min.js).



How can I do that using webpack.config.js?



Project structure:






js/
apps/
app.js

views/
v1.js // from here using templates, not by require
v2.js

templates/
t1.html // these are nunjucks files
t2.html

webpack.config.js







How using Nunjucks templates into JS codes (Backbone.js)?






module.exports = Backbone.View.extend({

t1Tpl: 't1.html', // template file path into templates/ directory

el: 'body',
...
...
render() {
$('body').html(global.nunjucksEnv.render(this.t1Tpl));
}
...
...
});





this was the previous gulp.task to precompile & concat the file:






const nunjucks = require('gulp-nunjucks');
...
...
gulp.task('templates', function() {
return gulp.src(paths.templates.files) // get all the templates/**/*.html files
.pipe(nunjucks()) // precompile
.pipe(concat('templates.min.js')) // concat into a single templates.min.js file
});





I want to do the exact task using Webpack Rules/Plugins configs.

  • From the top of my head I don't know whether there is a way to accomplish this (there surely is), but even if there is one, it wouldn't be "idiomatic webpack". What speaks against loading the template via the nunjucks-loader and require instead of stating the filename in the View (t1Tpl: require('nunjucks!./views/t1.html'))? It would even add the benefit of compile time errors if the template file name has a typo in the backbone view.

  • ok, then I've to do lots of change in every view file (I've thousands of view files & every file has multiple templates). It would be great if I can do this without changing in view files!

    Couldn't this be achieved mostly by search/replace? Replace Tpl: ' by Tpl: require('...

  • I need precompiled *.js file. If I do require('...'), it's not working with global.nunjucksEnv.render(this.t1Tpl) command.

  • Yes, the global.nunjucksEnv.render has to be slightly adjusted. It just has to call .render(params) on the passed parameter this.t1Tpl as described in tje docs of nunjuck-loader: var tpl = require('./views/page.njk'); var html = tpl.render({ message: 'Foo that!' });
