Node.js 10 requirement and more issues?

[danielpeintner]

A recent update related to coap-binding seems to require Node.js 10 to successfully run npm run bootstrap...

With version 8 I get lots of issues (e.g. also related to #10) while with Node.js 10 everything seems to work fine again.

1. I am not sure if it is already the time to switch
2. There are more issues with binding-websockets package
   node_modules/@types/ws/index.d.ts(179,24): error TS2694: Namespace '"net"' has no exported member 'AddressInfo'.
   Adding the following to ws.ts for example does the trick
   declare module 'net' {export interface AddressInfo {} }
3. TODO (we need to setup Travis again to avoid/notice such issues in the future)

The AddressInfo bug came from @types/ws: DefinitelyTyped/DefinitelyTyped#25890
It is fixed in 5.1.2, which is now the dependency for node-wot (5e68104).

NodeJS 10.* does not need the crypto polyfill (see https://github.com/AlCalzone/node-dtls-client/blob/master/install/postinstall.js), so no local compilation is needed then.

For versions < 10.* it should still work properly, given the prerequisites for node-gyp: https://github.com/nodejs/node-gyp#installation -- which is covered on Windows with the buildtools:

• Python 2.7
• make
• GCC

I will add this to the README for Linux and MacOS.

[danielpeintner]

The recent updates resolved the afore mentioned issues for node v10.

Running npm install -g --production windows-build-tools in CMD shell as administrator, as described in https://github.com/eclipse/thingweb.node-wot#windows, did NOT work for me with node v8.

Maybe an issue on my machine/installation. Do others experience the same issue?

For the last issue about Travis I opened another issue (see #22).

[mkovatsc]

Works for me on the "good" old Windows 7.

I remember an issue with the free Visual Studio compilers for Windows 10 and the need to manually install a specific version.

Which Windows and for 10 which build do you have?

[danielpeintner]

I am on Windows7 too.

Anyhow, node10 works... might really an issue n my side and I think we can close the issue
