Can't use together with expressions plugin

[cossssmin]

Found a weird issue: if you use posthtml-expressions together with this plugin, it will fail with either a TypeError or a ReferenceError (depending on which one you add to the plugins array first).

So this setup:

const html = `<fetch url="https://jsonplaceholder.typicode.com/users/1">
  {{ response.name }}
</fetch>`

posthtml([
    require('posthtml-expressions')({ locals: { var: 'test' } }),
    require('posthtml-fetch')()
  ])
    .process(html)
    .then(result => result.html)
    .catch(error => { throw error })

Fails with ReferenceError: response is not defined

If you switch plugin order, you get TypeError: nodes.reduce is not a function.

However, if you skip expression parsing with @{{ }}, it works 😵

<fetch url="https://jsonplaceholder.typicode.com/users/1">
  @{{ response.name }}
</fetch>

... that correctly outputs 'Leanne Graham' and the build doesn't break.

@Scrum any ideas? Is my setup wrong or is there a bug in the plugin?

@cossssmin Hi, I understand it like this:

1. If used @{{ response.name }} then the value is taken from the local scoup
2. If used {{ response.name }} then the value is taken from the global scoup
   and trying to find a variable in the global scope ({ locals: { var: 'test' } }) it fails

Yes, that's what I also understand is happening... But it shouldn't, and in fact you should be able to use it before posthtml-expressions like this:

posthtml([
    require('posthtml-fetch')()
    require('posthtml-expressions')({ locals: { var: 'test' } }),
  ])
    .process(html)
    .then(result => result.html)

But if you do that, you get an error in posthtml-expressions about nodes.reduce

[cossssmin]

Added a failing test in the expressions branch. As you'll see, it currently fails with:

TypeError {
  message: 'nodes.reduce is not a function',
}

@cossssmin I moved it because this is a package error posthtml-expression

Ah, ok, let me know if you need anything else from my side 👍
