ldapjs-promise-cel

LDAP Client and Server API for node.js with Promise support.

This is a simple wrapper around ldapjs for basic operations.

Installation

npm install --save ldapjs-promise-cel

Usage

For full docs, head on over to http://ldapjs.org.

The methods signatures are the same except instead of callbacks they return promises.

import * as ldap from 'ldapjs-promise-cel';

const client = ldap.createClient({
  url: 'ldap://127.0.0.1:1389',
  clientEventListener: (err) => {
      console.log(err);
  }
});
await client.bind(dn, password);

The ldapjs authors made the search method a special method that returns an EventEmitter so the user can handle each searchEntry as it is returned. Since this library is just wrapping ldapjs, it does not make any assumptions and returns the same EventEmitter. cel version - added createClient(options.clientEventListener) function register, that adds to the underlying ldapjs client client.on('error', clientEventListener), so it can handle connection resets and other extreme cases.

In order to await all of the results you could:

const results = client.search(base, options, controls).then(response => {
    const entries = [];
    let referrals = [];
    return new Promise((resolve, reject) => {
        response.on('searchEntry', entry => {
            entries.push(entry.object);
        });
        response.on('searchReference', referral => {
            referrals = referrals.concat(referral.uris);
        });
        response.on('error', error => {
            return reject(error);
        })
        response.on('end', result => {
            if (result.status !== 0) {
                return reject(result.status);
            }

            return resolve({
                entries: entries,
                referrals: referrals
            });
        });
    });
});

If this is exactly what you want, an extension method searchReturnAll has been added that does this.

const results = await client.searchReturnAll(base, options, controls);
for (let entry of results.entries) {
    ...
}
