Usage
tty.js is an app, but it's also possible to hook into it programatically.
var tty = require('tty.js');
var app = tty.createServer({
shell: 'bash',
users: {
foo: 'bar'
},
port: 8000
});
app.get('/foo', function(req, res, next) {
res.send('bar');
});
app.listen();
Configuration
Configuration is stored in ~/.tty.js/config.json or ~/.tty.js as a single
JSON file. An example configuration file looks like:
{
"users": {
"hello": "world"
},
"https": {
"key": "./server.key",
"cert": "./server.crt"
},
"port": 8080,
"hostname": "127.0.0.1",
"shell": "sh",
"shellArgs": ["arg1", "arg2"],
"static": "./static",
"limitGlobal": 10000,
"limitPerUser": 1000,
"localOnly": false,
"cwd": ".",
"syncSession": false,
"sessionTimeout": 600000,
"log": true,
"io": { "log": false },
"debug": false,
"term": {
"termName": "xterm",
"geometry": [80, 24],
"scrollback": 1000,
"visualBell": false,
"popOnBell": false,
"cursorBlink": false,
"screenKeys": false,
"colors": [
"#2e3436",
"#cc0000",
"#4e9a06",
"#c4a000",
"#3465a4",
"#75507b",
"#06989a",
"#d3d7cf",
"#555753",
"#ef2929",
"#8ae234",
"#fce94f",
"#729fcf",
"#ad7fa8",
"#34e2e2",
"#eeeeec"
]
}
}
Usernames and passwords can be plaintext or sha1 hashes.
256 colors
If tty.js fails to check your terminfo properly, you can force your TERM
to xterm-256color by setting "termName": "xterm-256color" in your config.
Security
tty.js currently has https as an option. It also has express' default basic
auth middleware as an option, until it possibly gets something more robust.
It's ultimately up to you to make sure no one has access to your terminals
but you.
CLI
tty.js --port 3000- start and bind to port 3000.tty.js --daemonize- daemonize process.tty.js --config ~/my-config.json- specify config file.
TERM
The main goal of tty.js is to eventually write a full xterm emulator.
This goal has almost been reached, but there are a few control sequences
not implemented fully. TERM should render everything fine when set to
xterm.
Portability
tty.js should ultimately be able to work on any unix that implements unix98
tty's and forkpty(3). tty.js builds on linux and osx, and it should build
on NetBSD, FreeBSD, and OpenBSD as well. If you have trouble building, please
post an issue.
Todo
The distance to go before full xterm compatibility.
- VT52 codes for compatibility
- All vt400 rectangle sequences
- Remaining DEC private modes
- Miscellaneous sequences: cursor shape, window title
- Origin Mode, Insert Mode
- Proper Tab Setting
