How to use ripple-lib-extension

[tuloski]

Hi guys, sorry my ignorance in js and npm and so on, but I'm not able to use this library. I have a root folder with the package.json to use RippleAPI, where all the node-modules were created. Now I cloned this ripple-lib-extension into the root folder and?? If I try to use RippleOrderbook it sais it is not defined. Should I add something into the package.json and do some npm install?

[tuloski]

I tried npm install inside the "orderbook" folder and the "value", but both fail. I have node 5.8.0 and npm version 4.0.2.

Noone? @shekenahglory ?

are you looking to use the orderbook in node or browser? navigate to the orderbook directory then run npm install - it should compile to the dist/npm directory. For browser, you need the extra step of running gulp, which will compile to the dist/web directory.

I tried that but I get:

None?

Is there someone still maintaining ripple-lib and ripple-lib-extensions?

@tuloski can you try running npm install with --verbose?

[tuloski]

Tell the author that this fails on your system: npm ERR! babel -D --optional runtime -d dist/npm/ src/

It is not able to compile.

@lumberj it is of course printing lots of stuff with --verbose. Are you interested in some of them?

Yea, just paste it all into a gist and link to it here On Thu, Mar 23, 2017 at 3:24 PM tuloski [email protected] wrote:

It's 30k lines :)

It got cut off. Maybe inspect the output for where the error occurs and just share that part

[tuloski]

The error is on the last lines....look for ERR!, but basically babel is failing to compile. The dist folder is not created.

1. clone the repo
2. go to the module directory
3. run npm install (in my case there were some errors)
4. refer to the generated files in dist/npm

const OrderBook = require('./ripple-lib-extensions/orderbook/dist/npm/orderbook').OrderBook;
const altnet = 'ws://s.altnet.rippletest.net:51233';
const api = new RippleAPI({
  server: altnet
});
api.connect().then(function() {

    var book = OrderBook.createOrderBook(api, {
      currency_pays: 'XRP',
      issuer_gets: 'rHjGuGDJvKQ2RSLj3WesnxVoKVVhbSwYQL',
      currency_gets: 'USD'
    });

    book.on('model', function(offers) {
      console.log(offers);
    });
});

@inmyth I have errors and the dist folder is not created

I tried this on Ubuntu 16.04 with node 7.10 and npm 4.2.0. It didn't work on Windows.

One thing to note is ripple-lib-extensions is not the package name. There are 4 packages in the 4 subdirectorries. You can find the package name in package.json. They can be installed with npm, e.g.

npm install -g ripple-lib-orderbook
