npm uninstall ziti-sdk-nodejs --save
npm install @openziti/ziti-sdk-nodejs --save

Usage

Note: the module must be installed before use.

ESM example (client-side)

import ziti from '@openziti/ziti-sdk-nodejs';

// Somehow provide path to identity file, e.g. via env var
const zitiIdentityFile  = process.env.ZITI_IDENTITY_FILE;
// Authenticate ourselves onto the Ziti network
await ziti.init( zitiIdentityFile ).catch(( err ) => { /* probably exit */ });

const on_resp_data = ( obj ) => {
    console.log(`response is: ${obj.body.toString('utf8')}`);
};

// Perform an HTTP GET request to a dark OpenZiti web service
ziti.httpRequest(
  'myDarkWebService',            // OpenZiti Service name or HTTP origin part of the URL
  undefined,                     // schemeHostPort parm is mutually-exclusive with serviceName parm
  'GET',
  '/',                           // path part of the URL including query params
  ['Accept: application/json' ], // headers
  undefined,                     // optional on_req cb 
  undefined,                     // optional on_req_data cb
  on_resp_data                   // optional on_resp_data cb
);

ESM example (server-side ExpressJS)

import ziti from '@openziti/ziti-sdk-nodejs';
import express from 'express';
let app = ziti.express( express, zitiServiceName );
app.listen(ignored, function() { ... }

/**

That's right.

With only a single-line code change (the ziti.express call), your web server is now capable
of being invisible to malicious attackers on the internet, and only accessible to your 
trusted remote users.

Nothing else in your existing ExpressJS web server code needs to change!

Existing routing, middleware, etc., all operates the same as it always did... 
but now you enjoy the comfort of knowing that if a connection comes in, it is from 
a trusted identity on the client side.

No malicious actors can see your dark web server, and thus, no malicious actors can attack it.

CJS example (client-side)

var ziti = require('@openziti/ziti-sdk-nodejs');

const ziti_init = async (identity) => {
    return new Promise((resolve) => {
        ziti.ziti_init(identity, () => {
            resolve();
        });
    });
};

const ziti_service_available = (service) => {
    return new Promise((resolve) => {
        ziti.ziti_service_available(service, (status) => {
            resolve(status);
        });
    });
};

function ziti_dial(service) {
    return new Promise((resolve, reject) => {
        ziti.ziti_dial(
            service,
            (conn) => {
                resolve(conn);
            },
            (data) => {
                // Do something with data...
            },
        );
    });
}

const ziti_write = (conn, data) => {
    return new Promise((resolve) => {
        ziti.ziti_write(conn, data, () => {
            resolve();
        });
    });
};

(async () => {

    await ziti_init(LOCATION_OF_IDENTITY_FILE);

    let status = await ziti_service_available(YOUR_SERVICE_NAME);

    if (status === 0) {

        const conn = await ziti_dial(YOUR_SERVICE_NAME);

        let data = SOME_KIND_OF_DATA;

        let buffer = Buffer.from(data);

        await ziti_write(conn, buffer);

        ...etc
    }

})();
