Simple RPC server and client for Node.js
npm i node-simple-rpc --save
Options :
var options = {
// Server host or ip address
host: 'localhost',
// Server port
port: 12345,
// Auth key, optional
auth: 'Your auth key',
// Max RPC Request length, defaults to 1MB.
// Used by server only
maxUploadSize: 1048576
};
Server :
const rpcServer = require('node-simple-rpc').server(options);
rpcServer.exports = {
helloWorld: (name, req, next) => {
next(null, "Hello " + name + "!");
},
add: (a, b, req, next) => {
next(null, a + b);
},
throwIfArgLte5: (arg, req, next) => {
if(arg <= 5) {
return next(new Error(arg + " <= 5"));
}
next(null, "Yo!");
},
// demonstrate multiple args
createFullName: (name, surname, next) => {
next(null, name, surname, name + ' ' + surname);
}
};
Client :
const rpcClient = require('node-simple-rpc').client(options);
rpcClient.helloWorld("John Doe", (err, result, req) => {
console.log(result);
// output : Hello John Doe!
});
rpcClient.add(1, 2, (err, result, req) => {
var args = req.input.data.args;
console.log("%s + %s = %s", args[0], args[1], result);
// output : 1 + 2 = 3
});
// Below call will output: "Error : 4 <= 5"
rpcClient.throwIfArgLte5(4, (err, result, req) => {
if(err){
return console.log("Error : %s", err.message);
}
console.log(result);
});
// Below call will output: "Yo!"
rpcClient.throwIfArgLte5(6, (err, result, req) => {
if(err){
return console.log("Error : %s", err.message);
}
console.log(result);
});
rpcClient.createFullName("John", "Doe", (err, name, surname, fullName, req) => {
console.log(fullName);
// output: John Doe
});
Server Middleware :
const rpcServer = require('node-simple-rpc').server(options);
rpcServer.use((req, next) => {
if(req.auth !== "Your auth key") {
return next(new Error("Unauthorized"));
}
next();
});
