How do I specify the base path for templates?

[slavafomin]

Hello!

Thank you for this great library!

However, how do I specify the base path for templates? The opts here doesn't have such option.

Thanks!

Right now, gulp-nunjucks uses the base path of the file that was passed to the plugin as the first argument that is passed to the nunjucks.FilesystemLoader constructor. This means that it is impossible to for instance include any files that live in any parent directory.

Maybe allow specifying paths in the compile signature?

@slavafomin You can work around it by passing a nunjucks.Environment in the options to compile like so:

.pipe(gnunjucks.compile({},{
  env: new nunjucks.Environment(new nunjucks.FileSystemLoader('some-base-path'))
}))

This base path will be used for all your require and extend statements.

Yup, that's the correct way to do it, else it falls back to file.base. https://github.com/sindresorhus/gulp-nunjucks/blob/master/index.js#L21.

Thanks @wolthers, for a suggestion!

I've found this module to have better API and more options:
https://github.com/carlosl/gulp-nunjucks-render

And it has path option out of the box. Gonna use it for now.

A slightly cleaner way around this can be achieved by using gulp-base:

.pipe(base('src'))
.pipe(nunjucks.compile())
.pipe(base('src/html'))

If you get

TypeError: nunjucks.FileSystemLoader is not a constructor

That is probably because you imported gulp-nunjucks as nunjucks, like

const nunjucks = require('gulp-nunjucks');

You need to import the original nunjucks like this:

const nunjucks_lib = require('nunjucks');

And usage could be like

gulp.src('some-base-path/file.template')
  .pipe(nunjucks.compile(data,{
    env: new nunjucks_lib.Environment(new nunjucks_lib.FileSystemLoader('some-base-path'))
  }))
  // ...

After around 5 years I've stumbled upon the same problem and had to use another package again :)

By the way, I still don't understand why this issue was closed.

After so many hours of investigation I've found out that all I had to do was add a second argument to the src function of gulp:

gulp.src('./docs/homepage/index.html', {base: './docs'})

Because gulp-nunjucks will fallback to this path, and so the ./docs will be the base path and all include statements in the Nunjucks code needs to be changed now to take this into consideration.

then I was able to include files in my templates which where outside the ./docs/homepage folder but still inside its parent folder.
