Supports mutiple sessions. 6 | 7 | NOTE: It is not a TTY emulator. It doesn't support complex TTY interaction like in vi, nano and etc. It's good only for simple command/response cases. For fully featured TTY emulator I would suggest [Wetty](https://github.com/krishnasrinivas/wetty) project. 8 | 9 | Prerequisites 10 | ------------- 11 | Node.js v0.10 or newer. 12 | 13 | Installation 14 | ------------ 15 | 16 | Install from npm: 17 | 18 | $ npm install web-terminal -g 19 | 20 | Usage Examples 21 | -------------- 22 | 23 | ### Starting web-terminal: 24 | 25 | $ web-terminal --port 8088 26 | 27 | Open your favorite web browser, navigate to http://localhost:8088 and start playing with the browser based CLI. 28 | 29 | ### Integrating web-terminal with web applications: 30 | ```javascript 31 | 32 | var http = require("http"), 33 | terminal = require("web-terminal"); 34 | 35 | var app = http.createServer(function (req, res) { 36 | res.writeHead(200, {"Content-Type": "text/plain"}); 37 | res.end("Hello World\n"); 38 | }); 39 | 40 | app.listen(1337); 41 | console.log("Server running at http://127.0.0.1:1337/"); 42 | 43 | terminal(app); 44 | console.log("Web-terminal accessible at http://127.0.0.1:1337/terminal"); 45 | 46 | ``` 47 | Start the above application, then open your favorite browser and navigate to: http://localhost:8088/terminal 48 | 49 | Features 50 | -------- 51 | 52 | ### Colors 53 | Most of the display VT100 escape sequences are translated to HTML. However, Web-terminal doesn't present itself as TTY and 54 | therefore most programs won't output escape sequences to **stdout** unless they are explicitly instructed so. 55 | 56 | Example configurations: 57 | 58 | $ git config --global color.ui always 59 | 60 | $ npm config set color always --global 61 | 62 | ### Shell commands 63 | To execute commands through a shell such as bash or cmd.exe (for windows), an environment variable have to be set: 64 | 65 | $ export WEB_SHELL=bash 66 | 67 | ### JavaScript REPL 68 | To start the REPL, just type **node** without arguments in the browser. 69 | Type **.exit** to return to the command prompt. 70 | NOTE: REPL is executed on the server, not in the brwoser. 71 | 72 | Issues 73 | ------ 74 | Commands that require interaction with TTY cause web-terminal to stop responding. 75 | 76 | For instance, commands like sudo that require password from TTY directly cause web-terminal to stop responding. In this case the whole process has to be restarted. 77 | 78 | The workaround for the time being is to issue sudo with -S argument to instruct sudo to ask for password on the standard IO. 79 | Example: 80 | 81 | $ sudo -S apt-get install git-core 82 | 83 | For Git, passwords have to be stored to avoid this problem: 84 | 85 | $ git config credential.helper store 86 | 87 | Security Considerations 88 | ----------------------- 89 | Web-terminal does not provide embedded authentication and encryption mechanisms. 90 | Therefore, if the service is exposed to the Internet, it is strongly recommended to require TLS with client certificates or VPN connection. 91 | 92 | License 93 | ------- 94 | 95 | (MIT License) 96 | 97 | Copyright (c) 2013 Boyan Rabchev .
