μRPC v5\n\nTransport agnostic bidirectional JsonRPC 1.0 implementation for browser and\nnode.js.\n\n### Install\n\nInstall via npm:\n\n```\nnpm i urpc\n```\n\nImport in browser:\n\n```html\n\u003c!-- UMD --\u003e\n\u003cscript src=\"https://unpkg.com/@urpc/build/urpc.umd.js\"\u003e\u003c/script\u003e\n```\n\nAnd then use in some script:\n```html\n\u003cscript\u003e\n  const rpc = new Urpc.Connection()\n\u003c/script\u003e\n```\n\nSingle-file ESM and CommonJS versions are also distributed with a\nbuild.\n\n### Usage\n\nHello world example. This is a simple endpoint which provide single\nmethod `greet(name)`, which returns a greeting message as a result.\n\n```javascript\nimport {Connection} from 'urpc';\n\nasync function handler({req, res}) {\n  if (req.method === 'greet') {\n    res.result = `Hello, ${req.params[0]}!`;\n  }\n};\n\n// Create listening (server) connection with custom server\nwsServer.on('connection', (conn) =\u003e {\n  const rpc = new Connection(handler);\n\n  // Message exchange\n  conn.on('message', (message) =\u003e {\n    rpc.write(message);\n  });\n\n  rpc.on('message', (message) =\u003e {\n    conn.write(message);\n  });\n\n  // Connection state syncing\n  conn.on('close', () =\u003e {\n    rpc.close();\n  });\n\n  rpc.on('close', () =\u003e {\n    conn.close();\n  });\n\n  // Call remote end with the same handler\n  rpc.call('greet', ['World'])\n  .then((result) =\u003e {\n    result; // \"Hello, World!\"\n  });\n\n  // Send notification\n  rpc.publish('event', []);\n});\n```\n\n## Codecs\n\nBy default all messages passed in or out of a connection is encoded and decoded\nvia built-in default codec (which is JSON). But you may use no codec:\n\n```js\nimport {Connection} from 'urpc';\n\nconst rpc = new Connection({\n  codec: null, // no codec\n});\n```\n\nOr define another codec:\n```js\nimport {Connection} from 'urpc';\nimport CBOR from 'cbor';\n\nconst cborCodec = {\n  encode(v) {\n    return CBOR.encode(v)\n  },\n  decode(v) {\n    return CBOR.decode(v)\n  },\n};\n\nconst rpc = new Connection({\n  codec: cborCodec,\n});\n```\n\n\n## License\n\nMIT © [Rumkin](https://rumk.in)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frumkin%2Furpc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frumkin%2Furpc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frumkin%2Furpc/lists"}
