How to use routes in seneca-web for rest api?

Question

I want to create rest API with seneca-web (express). I could not find any (full) documentation for a routes file used in it. I base one these examples. Let's assume i have a resource called Task. I want to have these http methods:

• GET /tasks
• GET /tasks/:taskId
• POST /tasks

Here is routes.js:

module.exports = [
  {
    prefix: '/tasks',
    pin: 'role:api,path:*',
    map: {
      all: {
        GET: true,
        prefix: ''
      },
      ':taskId': {
        GET: true
      }

    }
  },
  {
    pin: 'role:api,path:*',
    map: {
      tasks: {
        POST: true
      }

    }
  }
]

and my seneca plugin for handling:

module.exports = function task (options) {
  this.add({role: 'api', path: 'all'}, function (msg, respond) {
    console.log(msg)
    this.act('role:task,cmd:all', respond)
    respond(null, [{name: 'First Task', description: 'Description of     the First Task'}])
  })
  this.add({role: 'api', path: '*'}, function (msg, respond) {
    console.log(msg)
    this.act('role:task,cmd:single', {taskId: msg.args.params.taskId}, respond)
  })
}

• I am not sure how to separate POST and GET actions here.
• I found also problematic the fact that keys in map object of routes are taken as a part of a path, eg. GET /tasks/all instead of GET /tasks.

Thanks for any help.

here is example of seneca-web with routes

=========index.js=======

const seneca = require('seneca')()
const express = require('express')()
const web = require('seneca-web')
const cors = require('cors')

var Routes = [{
  prefix: '/products',
  pin: 'area:product,action:*',
  map: {list: {GET: true}}
}]
express.use(cors())
var config = {
  routes: Routes,
  adapter: require('seneca-web-adapter-express'),
  context: express,
  options: {parseBody: true}
}
seneca.client()
.use(web, config)
.ready(() => {
  var server = seneca.export('web/context')()
  server.listen('8082', () => {
    console.log('server started on: 8082')
  })
})
seneca.add({area: 'product', action: 'list'}, function (args, done) {
  try {
    done(null, {response: 'Product List'})
  } catch (err) {
    done(err, null)
  }
})

start app using command : node index.js

open link in your browser http://localhost:8082/products/list
