jsonrpc 2.0 end point for Express.js
jsonrpc2-express: JSON-RPC end-point for express
=========
Module to configure an express router in order to expose a JSON-RPC
end-point.
npm install jsonrpc2-express
``javascript
const express = require('express');
const jsonrpc = require('jsonrpc2-express')
const app = express();
let routerRpc = express.Router();
jsonrpc('/rpc/module1', routerRpc, {
methods: require('./module1.js'),
bodyParser: {
limit: '50mb'
}
});
app.use('/api', routerRpc);
app.listen(3000, function() {
console.log('Server listening on port 3000');
});
`
The file module1.js with the implementation of the different methods is:
`javascript
exports.f1 = function(req) {
console.log(req.body.params)
return {
field1: 'answer from f1',
user: req.user
};
};
exports.f2 = function(req) {
console.log(req.body.params)
return {
field1: 'answer from f2',
user: req.user
};
};
exports.ferror = function(req) {
throw new Error("sorry");
};
`
The parameters for each method can be read from req.body.params
