Connects node.js as a nrepl client to a Clojure nrepl server.
This is different from cljs-noderepl and similar projects as it does not connect node.js as the repl "target" (so that a nrepl Clojure client can eval code in a JS context) but the other way around ;)
To connect to a running nREPL server and send and receive an eval request do:
var nreplClient = require('nrepl-client');
nreplClient.connect({port: 7889}).once('connect', function() {
var expr = '(+ 3 4)';
client.eval(expr, function(err, result) {
console.log('%s => ', expr, err || result);
client.end();
});
});For a more detailed example and to use node.js also to start an nREPL Clojure process see examples/simple-connect.js.
## API
### `nrepl-client`
* `connect(options)`
* Creates a [`net.Socket`](http://nodejs.org/api/net.html#net_class_net_socket)
connection to an nREPL server. The connection object itself will have added
methods, see below.
* `options`: options from the [`net.connect`](http://nodejs.org/api/net.html#net_net_connect_options_connectionlistener) call.
* returns a `net.Socket` clojure connection
* clojure connection
* Wraps [nREPL messages](https://github.com/clojure/tools.nrepl#messages).
* `clone([session,] callback)
* `close([session,] callback)
* `describe([verbose,] callback)
* `eval(code, [session, id, evalFunc,] callback)
* `interrupt(session, id, callback)
* `loadFile(fileContent, [fileName, filePath,] callback)
* `lsSessions(callback)
* `stdin(stdin, callback)
* `send(msgObj, callback)` sends a custom message
### `nrepl-client/nrepl-server`
* `start(options, callback)`
* `options` options for configuring the nREPL server. Optional. `options == {startTimeout: NUMBER, verbose: BOOL, projectPath: STRING, hostname: STRING, port: NUMBER}`. See [nrepl-server.js](src/nrepl-server.js) for defaults.
* `callback(err, serverState)` function called when the server is started. `serverState == {proc: PROCESS, hostname: STRING, port: NUMBER, started: BOOL, exited: BOOL, timedout: BOOL}`
* `stop(serverState, callback)`
* `serverState` serverState returned from start
* `callback(err)` function called when the server is stopped
