SyntaxError: The requested module 'tydom-client' does not provide an export named 'createClient'

[mrwiwi]

Hi, new to node.js, could you please elaborate about how to use the module and the scripts ?

I installed it as guided, copied your simple client in a tydom.mjs file then tried node tydom.js (where i put my hostname, etc), but i got the error :

# node tydom.mjs (node:24059) ExperimentalWarning: The ESM module loader is experimental. file:///home/will/tydom.mjs:5 import {createClient} from 'tydom-client'; ^^^^^^^^^^^^ SyntaxError: The requested module 'tydom-client' does not provide an export named 'createClient' at ModuleJob._instantiate (internal/modules/esm/module_job.js:91:21) at async ModuleJob.run (internal/modules/esm/module_job.js:106:20) at async Loader.import (internal/modules/esm/loader.js:133:24)

I wish i could use it in nodered with home assistant...
Sorry if it's not the place to ask.

You should try without using modules in a plain .js file:

const {createClient} = require('tydom-client');

[mgcrea]

Actually the issue is that --experimental-modules doesn't support importing named exports from a commonjs module (except node's own built-ins) yet.

So another working code would be:

import tydomClient from 'tydom-client';
const {createClient} = tydomClient;

Thanks for the quick reply ! ;) And for the work !

My tydom.js :

`// Required when testing against a local Tydom hardware
// to fix "self signed certificate" errors
process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

//import {createClient} from 'tydom-client';
const {createClient} = require('tydom-client');

const username = '';
const password = '';
const hostname = '192.168..'; //'mediation.tydom.com'; // or '192.168.1.xxx'

const client = createClient({username, password, hostname});

(async () => {
console.log(Connecting to "${hostname}"...);
const socket = await client.connect();
// Get Tydom info
const info = await client.get('/info');
console.dir({info});
// Turn a light on
await client.put(/devices/${MY_DEVICE_ID}/endpoints/${MY_DEVICE_ID}/data, [

tried with your last suggestion ;)

[mgcrea]

You should set "type": "module" in your package.json

[mgcrea]

For the @babel/runtime/helpers/interopRequireWildcard I've just release a v0.4.1 that fixes it, update your package.json and npm i / yarn

[mrwiwi]

Working :) Time to play with it !

Any idea about how i can use it in nodered by the way ? (If you have a lead i could save me a lot of time and nerves :))

Could be really useful and compatible with almost all good home automation systems !

[mrwiwi]

Thanks a lot for your work !
