C++ is faster than JavaScript.
+          Is it?

+  

+

+
+

+  

+    If possible, write it in JavaScript.

+    JS   ⟷ C++ boundary is slow to cross
+  

+
+  
function() { return Math.floor(133.7 / Math.PI); }

+      
+

native JS ~83,333,333 calls/s
V8 return ~13,333,333 calls/s
V8 async ~1,745,200 calls/s
thread pool ~83,682 calls/s (0.1%)

+

+
+

+  

+    
Why C++?

+
+    
    
+      
  • V8 is written in C++
    • 
+      
  • Wrapping existing C/C++ libraries
    • 
+      
  • Use more threads
    • 
+

+
+

+  

+    Develop with

+    $ CXX=clang node-waf configure

+    Also test with GCC
+  

+

+
+

+  
Defining functions

+
+  
modulename.cpp

+  
+
+  
    
+    
  • HandleScope cleans up handles created in this function
    • 
+    
  • Preserve returned value with scope.Close()
    • 
+  

+

+
+

+  
Exporting functions

+
+  
modulename.cpp

+  
+
+  
    
+    
  • target is what node.js calls exports
    • 
+  

+
+  
+$ node
+>  var mod = require('./build/Release/modulename.node'); 
+{ theAnswer: [Function] }
+>  mod.theAnswer(); 
+42
+>  
+

+

+
+

+  
Function arguments

+
+  
modulename.cpp

+  
+
+  
    
+    
  • args contains elements of type Value
    • 
+    
  • Cast to specific type with To* functions
    • 
+  

+

+
+

+  
+

+
+

+  
Callback functions

+
+  
modulename.cpp

+  
+
+  
    
+    
  • Call automatically retains arguments
    • 
+    
  • Don’t forget HandleScope scope at the top
    • 
+  

+

+
+

+  
The thread pool

+  


+  
+
+  
    
+    
  • JavaScript is single-threaded
    • 
+    
  • I/O and CPU in thread pool
    • 
+    
  • No V8 access from worker!
    • 
+  

+

+
+

+  
Passing data to the thread pool

+
+  
+
+  
    
+    
  • Not required, just a convention
    • 
+    
  • Persistent is a Handle that stays around until diposed of
    • 
+  

+

+
+
+
+

+  
Calling asynchronously

+
+  
+

+
+

+  
Worker function

+
+  
+
+  
    
+    
  • Function AsyncWork is blocking
    • 
+    
  • Do not use any V8 code, not even variable reads
    • 
+    
  • Convert values to POD or C++ types and store them in the baton
    • 
+  

+
+

+
+
+

+  
After function

+
+  
+
+  
    
+    
  • callback function is Permanent, need to delete manually
    • 
+  

+
+

+
+

+  
Wrap callbacks in TryCatch

+
+  
+
+  
    
+    
  • node::FatalException throws at the top of the event loop
    • 
+    
  • Catchable with process.on('uncaughtException', ...)
    • 
+  

+
+

+
+
+

+  

+    
API design

+    
    
+      
  • Challenge: Synchronous ➞ Asynchronous
    • 
+      
  • Use EventEmitter
    • 
+      
  • Chainable calls
    • 
+      
  • Instantiating objects vs. functions
    • 
+      
  • Make it hard to misuse
    • 
+      
  • Make it feel as “JavaScripty” as possible
    • 
+    

+  

+

+
+
+

+  
node-sqlite3 API

+
+  
+
+  
    
+    
  • No open() function, new implicitly opens
    • 
+    
  • Statements are executed as soon as database is open
    • 
+    
  • No need to “close” the database
    • 
+    
  • No callback? 'error' event on the Database object
    • 
+

+
+

+  
node-blend API

+  
    
+    
  • Blends two images of the same size
    • 
+  

+
+  
+
+  
    
+    
  • No need to create objects with new if you don’t require state
    • 
+  

+

+
