Quick example does not work

[djensen47]

I cloned the repository. Did an npm install. Went into the examples directory. Ran node using-hapi.js and received the following error:

It looks like the examples in the docs directory were not updated to use a require statement instead of a string. I can submit a pull request to fix this tomorrow-ish.

[dgonzalez]

That would be awesome. If you need any help, please ping me. I might be able to assist you.

[djensen47]

Also, the getting started guide for Seneca is maybe using an old example of how to integrate seneca with a web server: http://senecajs.org/getting-started/#web-server-integration

There is no reference to seneca-web in this section and I think the example only works on Express? Maybe that's an issue for the seneca repo but I thought I might mention it here too.

Hi djensen47 ,

Yes, the example is no longer synchronized with current state of plugins. I ran into the same problem with the express example. The issue is that the adapter can no longer be called as stated in the code. You must require a special plugin for Express located here : https://github.com/senecajs/seneca-web-adapter-express

Now after moving some files for my personal arrangement, I was able to make it run :

'use strict'
var Seneca = require('seneca')
var Express = require('express')
var Web = require('seneca-web')
var Routes = require('./routes')
var Plugin = require('./plugin')

var config = {
    routes: Routes,
   adapter: require('seneca-web-adapter-express'),
   context: Express()
 }

var seneca = Seneca() .use(Plugin) .use(Web, config)
 .ready(() => {
    var server = seneca.export('web/context')()

  server.listen('4000', () => {
  console.log('server started on: 4000')
})

})

The point is to require 'seneca-web-adapter-express' and pass it as the adapter. The same seems to go for hapi, have a look at https://github.com/senecajs/seneca-web-adapter-hapi

Hope this can help.

[djensen47]

Yup, thanks, helpful. I discovered this the other day too.

Hi Dave,

What do you get exactly and how do you send your request ?

Also, it appears that the Express example doesn't work at all even when using require for the adapter.

I didn't understand the question but I went ahead and fixed the examples with #112.

[imatmati]

Good, I was thinking about those changes, but you did it. Now, all examples will be ... working examples.
