Bun 1.2 Released with 90% Node.js Compatibility and Built-in S3 Object Support
Bun 1.2 enhances its JavaScript runtime with 90% Node.js compatibility, built-in S3 and Postgres support, HTML Imports, and faster, cloud-first performance.
This is a port of ZeroRPC to node.js. We have full client and server support for version 2 of the protocol, however there are issues with legacy support.
This project is alpha.
To install the package:
npm install zerorpc
To create a new server:
var zerorpc = require("zerorpc");
var server = new zerorpc.Server(context);
The constructor takes in a context object with the functions to expose over RPC. Only functions that do not have a leading underscore will be exposed. Each exposed method must take in a callback as the last argument. This callback is called as callback(error, response, more)
when there is a new update, where error is an error object or string, response is the new update, and more is a boolean specifying whether new updates will be available later.
Events:
error
- When an error occurs.Methods:
bind(endpoint)
- Binds the server to the specified ZeroMQ endpoint.connect(endpoint)
- Connects the server to the specified ZeroMQ endpoint.close()
- Closes the ZeroMQ socket.Full example:
var zerorpc = require("zerorpc");
var server = new zerorpc.Server({
addMan: function(sentence, reply) {
reply(null, sentence + ", man!", false);
},
add42: function(n, reply) {
reply(null, n + 42, false);
},
iter: function(from, to, step, reply) {
for(i=from; i<to; i+=step) {
reply(null, i, true);
}
reply(null, undefined, false);
}
});
server.bind("tcp://0.0.0.0:4242");
server.on("error", function(error) {
console.error("RPC server error:", error);
});
To create a new client:
var zerorpc = require("zerorpc");
var client = new zerorpc.Client(options);
The constructor optionally takes in an options object. Allowable options:
timeout
(number) - Sets the number of seconds to wait for a response before considering the call timed out. Defaults to 30.Events:
error
- When an error occurs.Methods:
bind(endpoint)
- Binds the server to the specified ZeroMQ endpoint.connect(endpoint)
- Connects the server to the specified ZeroMQ endpoint.close()
- Closes the ZeroMQ socket.invoke(method, arguments..., callback)
- Invokes a remote method.
method
is the method name.callback
is a method to call when there is an update. This callback is called as callback(error, response, more)
when there is a new update, where error is an error object, response is the new update, and more is a boolean specifying whether new updates will be available later.Full example:
var zerorpc = require("zerorpc");
var client = new zerorpc.Client();
client.connect("tcp://127.0.0.1:4242");
client.on("error", function(error) {
console.error("RPC client error:", error);
});
client.invoke("iter", 10, 20, 2, function(error, res, more) {
if(error) {
console.error(error);
} else {
console.log("UPDATE:", res);
}
if(!more) {
console.log("Done.");
}
});
