Wa-automate-nodejs: Feature: Expose a basic express middleware from Client

[smashah]

Implementing this library with express shouldn't be so complicated and verbose. A simple middleware should be able to manage the vast majority of functionality from the client. This feature needs to be implemented with minimal increased library footprint.

How to use the middleware:

import { create } from '@open-wa/wa-automate';
const express = require('express')
const app = express()
app.use(express.json())
const PORT = 8082;

function start(client){
  app.use(client.middleware);
  app.listen(PORT, function () {
    console.log(`\n• Listening on port ${PORT}!`);
  });
  ...
}


create({
  sessionId:'session1'
}).then(start)

All requests need to be POST requests. You use the API the same way you would with client. The method can be the path or the method param in the post body. The arguments for the method should be properly ordered in the args array in the JSON post body.

Example:

  await client.sendText('[email protected]','test')
  //returns "[email protected]_3EB0645E623D91006252"

as a request with a path:

const axios = require('axios').default;
axios.post('localhost:8082/sendText', {
    args: [
       "[email protected]",    
       "test"    
        ]
  })

or as a request without a path:

const axios = require('axios').default;
axios.post('localhost:8082', {
    method:'sendText',
    args: [
       "[email protected]",    
       "test"   
        ]
})

I will continue to explore it.

Thanks

Hello,
I cant seem to send an image. I am wsing the latest version of the library and was able to get most things to work except sending of files.
it usually returns b64Data.split is not a function among other errors. My simple axios request is as follows

const file = 'iVBORw...cx';
const axios = require('axios').default;
axios.post('http://localhost:8082/sendFile', {
    args: [
        "[email protected]",
        [file],
        'ing.png',
        'ntesho!'
    ]
}).then((res) => console.log(res.data))
    .catch(err => console.log(err))

Thanks once again for your incredible work.

afaik you need to send the base64 data directly. Here is how i send it (not with the REST api, mind you)

client.sendImage(
          to,
          `data:${mime.lookup(FILE)};base64,${fs.readFileSync(FILE).toString('base64')}`,
           FILE.substring(FILE.lastIndexOf('/') + 1).trim(),
          caption
        );

Here i am using the libs mime and fs in node.
mime to lookup the mimetype and then fs to open and read the FILE.

Note that FILE is a filepath

Oh. Thanks. I will try that in a minute
