Jasper Server REST v2 API client for publishing and running reports.

Usage

const jasperclient = require('jasperclient');
const fs = require('fs');

let client = new jasperclient({
    host: 'jasper.example.com',
    path: 'jasperserver',
    username: 'username',
    password: 'password',
    useBasicAuth: true,
});

// Publish a report
let publishResponse = client.reports.publish({
    path: '/Reports/Dummy',
    label: 'Dummy Report',
    datasource: '/datasources/Dummy',
    jrxml: Buffer.from(fs.readFileSync('./dummy.jrxml'),'UTF-8').toString('base64'),
    resources: [
        {
            'name': 'img.png',
            'file': {
                'fileResource': {
                    'type': 'img',
                    'label': 'img.png',
                    'content': Buffer.from(fs.readFileSync('./img.png')).toString('base64'),
                },
            },
        },
        {
            'name': 'sub.jrxml',
            'file': {
                'fileResource': {
                    'type': 'jrxml',
                    'label': 'sub.jrxml',
                    'content': Buffer.from(fs.readFileSync('./sub.jrxml'),'UTF-8').toString('base64'),
                },
            },
        }
    ],
});

// Fetch a report
let runResponse = client.reports.run({
    path: '/Reports/Dummy.pdf',
    format: 'pdf',
    params: {
        input1: 'value1',
        input2: 'value2',
    },
},{
    responseType: 'stream',
});

let writer = fs.createWriteStream('./dummy.pdf');

runResponse.data.pipe(writer);

writer.on('finish', function () {
    console.log('Successfully wrote file to ./dummy.pdf');
    // client.logout(); // only useful if useBasicAuth is false
});

writer.on('error', function (err) {
    console.log('Failed to write file: ',err);
    // client.logout(); // only useful if useBasicAuth is false
});

Constructor

@class - jasperclient -- Jasper Server REST API client for publishing and running reports.
@param { Object}  opt - Required configuration data.
@param { string}  opt.proto [http] - Protocol to use; optionally set to https.
@param { string}  opt.host - Hostname of the Jasper server.
@param {!number}  opt.port - Port number of the server (default is undefined).
@param {!string}  opt.path - Path of the server after the hostname (i.e. jasperserver).
@param {!string}  opt.username - Username to use when authenticating with the Jasper server.
@param {!string}  opt.password - Password to use with the username.
@param {!Boolean} opt.userBasicAuth - Send Basic Authorization header instead of using cookies (default is false)

Methods

login()

@function login - Create a cookie-based session with the Jasper server.  If the username and password
                  were provided to the constructor then they can be ommitted here, and it becomes
                  unneccessary to call this method directly; it will be called automatically when
                  the first request is made.
@async
@param {!string} opt.username - Username to use when authenticating with the Jasper server.
@param {!string} opt.password - Password to use with the username.
@returns {Promise<string>} - Resolves JSESSIONID upon success.
                           - Rejects with error string on failure.

logout()

@function logout - End the current session with the Jasper server.
@async
@returns {Promise<Object>} - Resolves an Axios response (see https://github.com/axios/axios#response-schema ).

request()

@function request - Send a request to the jasper server.  If a username and password
                    were provided to the constructor then a login will be performed
