6. Slow Installation • “npm install fengdie” took 2m12.560s • Great-Wall’ed

   in China • Remembered to use npm -g with sudo?

7. Too much complexities • “Should I care about those WARN’s?”

   • “or should I not?”

8. Node.js Runtime? • Making sure your user used the correct

   Node.js • Could multiple Node.js versions co-exist? • Wish to use ECMAScript 2017?

28. How it Works

29. Introducing /__enclose_io_memfs__ a “mounted” disk in RAM for your project

30. None

31. Basic Idea System calls on paths starting with
 /__enclose_io_memfs__
 are

    redirected to the RAM while others to the FS

32. /__enclose_io_memfs__/… others Image Curtesy: Evan-Amos

36. But there are so many API’s • require, require.resolve •

    fs.readFile, fs.readFileSync, fs.ReadStream • fs.readlink, fs.stat, fs.statSync, fs.readlinkSync • …

37. Yet we did this in 8 files only

38. That’s because… https://github.com/pmq20/libsquash libsquash https://github.com/pmq20/node-compiler Node.js Compiler

39. Introducing SquashFS

40. SquashFS • a compressed read-only file system • used by

    the Live CD versions of Arch Linux, Debian, Fedora, Gentoo, Mint, Salix, Ubuntu • used on OpenWrt and DD-WRT router firmware

41. fengdie’s
 node_modules/ 148M fengdie.squashfs 16M

42. SquashFS • Introduced in 2009 with Linux 2.6.29 • File

    format very stabilized • Unsquashfs and mksquashfs have win32 ports; 7-Zip on win32 also supports SquashFS • Part of kernel; GPL Licensed

43. Introducing libsquash

44. https://github.com/pmq20/libsquash libsquash • MIT licensed • Super embeddable • 1

    dependency only, which could be statically linked • Compiles on 3 platforms, even Windows XP with VC++ 2010 • Introduces VFD - virtual file descriptor, intercepting system calls unobtrusively libsquash

45. API of libsuqash mirroring system calls

46. Virtual File Descriptor generated by a duplicating file descriptor 0

47. Use libsquash unobtrusively Just include a header and it’s done!

48. Use libsquash unobtrusively Win32 API works as well

49. Hard-code an Entrance

50. node ~/fengdie/bin/cli.js (argv[1] preset to /__enclose_io_memfs__/bin/cli.js) ./fengdie

51. fengdie/*

52. fengdie/* fengdie.squashfs mksquashfs

53. fengdie/* fengdie.squashfs libsquash compile

54. fengdie/* fengdie.squashfs libsquash Node.js Runtime compile

55. fengdie/* fengdie.squashfs libsquash Node.js Runtime

56. fengdie/* fengdie.squashfs libsquash Node.js Runtime

57. fengdie/* fengdie.squashfs libsquash Node.js Runtime fengdie.exe Statically Link Statically Link

58. fengdie/* fengdie.squashfs libsquash Node.js Runtime fengdie.exe Statically Link Statically Link

59. fengdie.exe Distribute and Enjoy

60. Download & Install

61. nodec is also enclosed Operating System Architecture Download Link Windows

    x86 https://sourceforge.net/projects/ node-compiler/files/v0.9.4/ nodec.exe/download macOS x86-64 https://sourceforge.net/projects/ node-compiler/files/v0.9.4/nodec- darwin-x64/download Linux x86-64 https://sourceforge.net/projects/ node-compiler/files/v0.9.4/nodec- linux-x64/download

62. Install on Windows • SquashFS Tools 4.3 • Python 2.6

    or 2.7 • Visual Studio 2015 Update 3, all editions including the Community edition (remember to select "Common Tools for Visual C++ 2015" feature during installation). • Then download the executable nodec.exe and run it from the VC++ or VS Command Prompt.

63. Install on macOS • SquashFS Tools 4.3: brew install squashfs

    • Xcode + Command Line Tools • Python 2.6 or 2.7 • GNU Make 3.81 or newer

64. Install on macOS • curl -L https://sourceforge.net/projects/node- compiler/files/v0.9.4/nodec-darwin-x64/ download >

    nodec • chmod +x nodec • ./nodec

65. Install on Linux • SquashFS Tools 4.3 • gcc and

    g++ 4.8 or newer, or • clang and clang++ 3.4 or newer • Python 2.6 or 2.7 • GNU Make 3.81 or newer

66. Install on Linux • curl -L https://sourceforge.net/projects/node- compiler/files/v0.9.4/nodec-linux-x64/download > nodec

73. Applications

74. Quicker Install / Upgrade • Quicker upgrading embedded node.js applications

    / plugins • Quicker upgrading embedded node.js applications / plugins • E.g. fengdie inside the Tea IDE

75. Enabling Node.js Developers • Build softwares instead of modules •

    Distribute to non-technical users • Merchandise by building personal / enterprise softwares

76. Code Protection • Enable code signing for the entire application;

    guarantee not being altered or corrupted • Prevent hacking by users modifying exposed Javascript source code • Applicable to NW.js applications (DingTalk) and Electron applications (Tea)

77. Tips

78. Use --tmpdir=/a/fixed/location

79. Use CentOS release 5.8
 with gcc and g++ 4.8
 (possibly

    from devtoolset-2 of slc5-devtoolset)

80. Use Windows
 with a big Virtual Memory

81. Check dependencies using Dependency Walker, otool, ldd
 before releasing
