Simple REST

Simple REST framework.

This is alpha version, API may change drastically with major versions. Performance is probably bad.

Installation

npm install simple-rest

Usage

rest = require("simple-rest");

// Example
// If you return string response gets Content-Type: text/plain automatically.
rest.get("/test", function() {
  return "return text/plain string";
});

// Automatic variable name mapping (order of arguments in function doesn't matter)
// e.g. /user/1/name --> 1, name
rest.get("/user/:userId/:userProperty", function(userProperty, userId) {
  return userId+", "+userProperty;
});

// chaining
rest
  // if you return simple object then the response
  // has Content-Type: application/json automatically
  .get("/object", function () {
    return {msg: "return as application/json"};
  })

  // automatic setting Content-Type via function name
  .get("/pdf", function asApplicationPdf() {
    return {msg: "return as application/pdf"};
  })
  // POST
  .post("/post", function asNonExistent() {
    return "why"; // Content-Type: non-existent
  })

  // file download? no problem!
  .get("/file", function(File) {

    return File("package.json");

  })

  // auto-wire core module? not a problem!
  .delete("/file/:name", function returnsStatusCode(fs, name) {
    if(! fs.existsSync(name)) {
      return 404;
    } else {
      fs.unlinkSync(name);
      return 200;
    }
  })

  // asynchronous version of above
  // Note: if Async is injected then framework automatically assumes
  //       asynchronous callback will be called and ignores return
  //       value of handler.
  .delete("/fileAsync/:name", function returnsStatusCode(fs, name, Async) {
    fs.exists(name, function(exists) {

      setTimeout(function(){
        console.log("Unlink "+name);
        if(! exists) {
          Async(404);
        } else {
          fs.unlinkSync(name);
          Async(200);
        }
      }, 1000);

    });
  });
