node-builder

I wrote this small bit of code to make it easier to create static JavaScript programs. It automatically “compiles” your own built-in 3rd party JavaScript file(s) with Node.js as a single standalone binary file. It’s still far from perfect and more like a proof of concept than an actual program.

Our test file dummy.js looks like this:

console.log("I am a dummy.js");

You can compile it by running:

$ node-builder.js -q -o dummy dummy.js

...and execute the binary file in usual way:

$ ./dummy
I am a dummy.js

Resulting binary file is a real binary file:

$ file dummy
dummy: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, not stripped

Only ./dummy file is needed to execute your program. Nothing else needs to be installed. (Except external modules, which node-builder doesn’t include in the executable (unless provided with the binary) but I probably will figure some way to support those too.)

This all works by using 3rd party support in Node.js. At the moment it does not actually precompile the source code into the executable like it is done for the standard library with Google v8. Maybe that will be supported someday. The code is simply included as it is inside the binary.

Something went wrong with that request. Please try again.
