@mariodeckers/nmb2b-client v1.0.0-beta.4.1

Network Manager B2B Client

forked from DGAC/nmb2b-client-js

Exposes a general purpose Javascript library to interact with NM B2B web services. The idea is to abstract pain points while offering an API that maps the NM B2B WS API.

NM target version: 26.0.0

Simple usage example

https://github.com/DGAC/nmb2b-client-js-example

Features

• No WSDL/XSD dependency. The library will download and cache those on start up.
• Natural serialization/deserialization of certain types.

For instance, the Flow.retrieveOTMVPlan query expects a day attribute with the XSD type DateYearMonthDay. This type is a string, representing a date in the YYYY-MM-DD format. This library allows you to pass a traditional JS Date object instead.

const res = await Flow.retrieveOTMVPlan({
  dataset: { type: 'OPERATIONAL' },
  day: new Date(),
  otmvsWithDuration: { item: [{ trafficVolume: 'LFERMS' }] },
});

• Request object key reordering when needed.

In SOAP, key order matters.

// OK
await Flow.retrieveOTMVPlan({
  dataset: { type: 'OPERATIONAL' },
  day: moment.utc().toDate(),
  otmvsWithDuration: { item: [{ trafficVolume: 'LFERMS' }] },
});

// Would normally fail
await const Flow.retrieveOTMVPlan({
  day: moment.utc().toDate(),
  dataset: { type: 'OPERATIONAL' },
  otmvsWithDuration: { item: [{ trafficVolume: 'LFERMS' }] },
});

The library reorder request object keys to match what's expressed in the XSD/WSDL. Therefore, the second example works fine.

• TypeScript support.

The following example will raise a type error.

// Raises a type error
await Flow.retrieveOTMVPlan({
  dataset: { type: 'OPERATIONNAL' }, // Notice the typo
  day: moment.utc().toDate(),
  otmvsWithDuration: { item: [{ trafficVolume: 'LFERMS' }] },
});

• Debug output

Debug output is controlled via the debug package. All debug output from this library is scoped under @dgac/nmb2b-client namespace.

Just set a DEBUG=@dgac/nmb2b-client* environment variable :

Usage

Main service

import makeB2BClient from '@dgac/nmb2b-client';

// See below for more information about the security argument
const client = await makeB2BClient({ security });

const res = await client.Airspace.queryCompleteAIXMDatasets();

Per domain service

import { makeAirspaceService } from '@dgac/nmb2b-client';

// See below for more information about the security argument
const Airspace = await makeAirspaceService({ security });

const res = await Airspace.queryCompleteAIXMDatasets();

Error handling

import { makeAirspaceService, NMB2BError } from '@dgac/nmb2b-client';

try {
  const Airspace = await makeAirspaceService({ security });

  const res = await Airspace.queryCompleteAIXMDatasets();
} catch (err) {
  if (err instanceof NMB2BError) {
    if (err.status === 'OBJECT_NOT_FOUND') {
      // ...
    }
  }

  // ...
}

B2B Security

Every request to the NM B2B web services must be authenticated using a client certificate. This library needs to be initialized with a security object, containing the certificate, key and passphrase associated.

With P12 certificate

import fs from 'fs';

const security = {
  pfx: fs.readFileSync('/path/to/cert.p12'),
  passphrase: 'your-passphrase',
};

makeB2BClient({ security }).then((client) => {
  client.Airspace.queryCompleteAIXMDatasets().then(() => {});
});

With PEM certificate

import fs from 'fs';

const security = {
  pem: fs.readFileSync('/path/to/cert.pem'),
  key: fs.readFileSync('/path/to/cert.key'),
  passphrase: 'your-passphrase',
};

makeB2BClient({ security }).then((client) => {
  client.Airspace.queryCompleteAIXMDatasets().then(() => {});
});
