I'm eager to test this out on my project rurudb, a prototypal db which currently uses JSON.parse against loaded db file JSON string.

Sad thing is I don't know shit about C++ so this might be tricky.

I'm on Win7 x64 with visual studio build tools, and have existing packages in my projects which are also built using node-gyp.

Hi @davalapar, I don't understand your problem very well because this output is very unclear to me (there are years that I don't use Windows).

According to your error message, it seems to be a problem with your C++ default compiler.
This error here for example: c:\cygwin64\home\1234\rurudb\node_modules\simdjson\simdjson\src/simdjson.h(462): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

I checked the line on the simdjson.h file line 462 and it was fine: std::string_view get_corpus(const std::string& filename);

Also you get this error: c:\cygwin64\home\1234\rurudb\node_modules\simdjson\simdjson\src/simdjson.h(462): error C2039: 'string_view': is not a member of 'std' (compiling source file ..\simdjson\main.cpp) [C:\cygwin64\home\1234\rurudb\node_modules\simdjson\build\simdjson.vcxproj]

So I think that it could be that you don't have (or Windows doesn't have) the type string_view.

Do you think you could change the c++(possibly to clang++ or g++) compiler?

Let me know if you can do it! I can try to build it in a Windows machine I have over the weekend, in case you keep getting errors! Cheers

Hey @davalapar, have you tried npm install simdjson?

I am saying that because I found the following: yarnpkg/yarn#5115

Hey @davalapar, have you tried npm install simdjson?

Yes, however it's same error.

I think that it could be that you don't have (or Windows doesn't have) the type string_view.

Seems right, it appears that string_view is an std stuff in C++ 17 and it's my outdated node-gyp version causing this.

I tried adding:

			'msvs_settings': {
				'VCCLCompilerTool': {
					'AdditionalOptions': [ '-std:c++14' ]
				}
			}

to make it look like

{
    "targets": [{
        "target_name": "simdjson",
        "sources": [
            "simdjson/main.cpp",
            "simdjson/bindings.cpp",
        ],
        'include_dirs': [
            "<!@(node -p \"require('node-addon-api').include\")"
        ],
        "libraries": ["~/Projects/simdjson/build/libsimdjson.0.0.1.dylib"],
        'dependencies': [
            "<!(node -p \"require('node-addon-api').gyp\")"
        ],
        'defines': [ 'NAPI_DISABLE_CPP_EXCEPTIONS' ],
			'msvs_settings': {
				'VCCLCompilerTool': {
					'AdditionalOptions': [ '-std:c++14' ]
				}
			}
    }]
}

and the error will persist (as it should), but when I tried replacing -std:c++14 with -std:c++17 it will then say an extra error that it doesn't recognize it as a flag.

cl : Command line warning D9002: ignoring unknown option '-std:c++17' [C:\simdj
son_nodejs\build\simdjson.vcxproj]
cl : Command line warning D9002: ignoring unknown option '-std:c++17' [C:\simdj
son_nodejs\build\simdjson.vcxproj]

Do you think you could change the c++(possibly to clang++ or g++) compiler?

I think updating my outdated node-gyp or workstation (win7 lol) for now would be worth a shot, I'll re-open this issue instead if the issue persist on that case. Thank you!!

Hi @davalapar, I think I fixed your problem. I haven't merged into master because I am still working on it, but if you want, you can download it on this branch here: https://github.com/luizperes/simdjson_nodejs/tree/issue-6

Thanks for the feedback! However, I believe that your project is using the default JSON parser, since I am still giving support to it, in case that it fails for avx2. You will see that you are only compiling the nonavx2.cpp file.

I think I just fixed this problem for windows (both the warning for <nan.h> and the problem that it wouldn't compile properly. I would really appreciate if you could update your issue-6 branch and try to compile it. Please also post the output here, so I can check if it is working properly for windows.

Oh! One way to check if it is working properly is by running the benchmarks:

  • cd benchmark
  • node benchmark.js

The output should be something like:

Luizs-MacBook-Pro:benchmark luizperes$ node benchmark.js 
apache_builds.json#simdjson x 5,433 ops/sec ±0.39% (94 runs sampled) => 0.00018407286098149627
apache_builds.json#JSON x 1,430 ops/sec ±1.06% (89 runs sampled) => 0.0006994615262760572

See that for simdjson it did 5,433 ops/sec, but for JSON it did 1,430 ops/sec.
If the number of operations are close to each other (in the house of the 1000s, then it means that your project is using simdjson as an alias for JSON.

Please let me know how it goes! Thanks for contributing to this project!

Hi @luizperes, seems that you're right. Tested the issue-6 branch and the latest master branch and both shows the initial c++17 error I had before.

I'm currently installing VS build tools 2017 for node-gyp, will get back to you if it works out!

Thank you, I will have to study them, because you keep getting problems with string_view. It could be that we are not passing a flag -std=c++17 to the VS

Yes I saw it too, I tried adding '/std:c++17',

        ]
      }
    ]
  ]
}

which got rid of string_view related errors, but then some warnings still show up. Also tried running benchmark at this point but it won't proceed (just exits).

The flags "/mavx2", "/mavx", "/mbmi", "/mpclmul" can all be removed, I thought that they were needed (such as in Linux and Mac OS). Did you get anything running?

Also, that would be cool if you could open a PR on your fixes for Windows. Thanks!

Just opened the PR, I've removed those flags yet some warnings still show up, and when I try to run the benchmark it just abruptly exits without any errors / warnings.

Also tried requiring it, but it also exits w/o errors or warnings:

C:\simdjson_nodejs>node
> x = require("./index")
{ hasAVX2: [Function], isValid: [Function], parse: [Function] }
> x
{ hasAVX2: [Function], isValid: [Function], parse: [Function] }
> x.parse('{ "a": 1}');

C:\simdjson_nodejs>

I've checked a couple issues in node-gyp repo and it seems that on warnings like these (shown in pr) they are telling people that it's not a problem in node-gyp

How about any of the other functions: hasAVX2, isValid? Do they work?

Just teted, hasAVX2 works, isValid exits like parse:

C:\>cd simdjson_nodejs

C:\simdjson_nodejs>node
> x = require('./index')
{ hasAVX2: [Function], isValid: [Function], parse: [Function] }
> x.hasAVX2() // works
true
> x.isValid('x') // exits

C:\simdjson_nodejs>node
> x = require('./index')
{ hasAVX2: [Function], isValid: [Function], parse: [Function] }
> x.isValid('{ "a": 1 }'); // exits

C:\simdjson_nodejs>

So... the hasAVX2 only checks if the flag __AVX2__ was passed. isValid actually calls the simdjson lib. I wonder if you really have avx2, have you ever tested it? That is so unusual, I would expect you to get a crash or mixed up values, but no response is weird. This project here would help you to check if you have AVX2 https://github.com/Mysticial/FeatureDetector

Oooooh! The flag NAPI_DISABLE_CPP_EXCEPTIONS will prevent the code from throwing exceptions!!! That sucks! would you try to compile the files related to simdjson directly?

They can be found on:
./simdjson/src/simdjson.h
./simdjson/src/simdjson.cpp

You might find directions on how to compile them here: https://devblogs.microsoft.com/cppblog/building-your-c-application-with-visual-studio-code/

Don't forget to add the flags: '/std:c++17' and "/arch:AVX2"

Got this, it created .pdb and .obj files:

https://i.imgur.com/WPFRfYx.png

Also tried the try-catch thing, both variants show no error / warning, just exits.

const simdjson = require('../simdjson_nodejs'); // pr branch on separate folder

const sample1 = JSON.stringify({
  a: 1,
  b: 3
});

try {
  simdjson.parse(sample1);
} catch (e) {
  console.error(e);
}
const simdjson = require('../simdjson_nodejs'); // pr branch on separate folder

const sample1 = JSON.stringify({
	a: 1,
	b: 3
});

try {
  simdjson.isValid(sample1);
} catch (e) {
  console.error(e);
}

I wonder if you have to add the flas /Od /Zi /EHsc to the binding.gyp file such as:

"msvs_settings": {
  "VCCLCompilerTool": {
    "AdditionalOptions": ["/std:c++17", "/arch:AVX2", "/Od", "/Zi", "EHsc"]
  }
}

Would that work for you?

Otherwise, it is also possible to use a path for a library file on binding.gyp. You could try to add that library your compiled library (is there a way to compile to the standard .dll?). You could replace the binding.gyp file completely with:

binding.gyp

{
    "targets": [{
        "target_name": "simdjson",
        "cflags!": [ "-fno-exceptions" ],
        "cflags_cc!": [ "-fno-exceptions" ],
        "sources": [
            "simdjson/main.cpp",
            "simdjson/bindings.cpp",
        ],
        "include_dirs": [
            "<!@(node -p \"require('node-addon-api').include\")"
        ],
        "libraries": ["/path/to/library/libsimdjson.dll"],
        "dependencies": [
            "<!(node -p \"require('node-addon-api').gyp\")"
        ],
        "defines": [ "NAPI_DISABLE_CPP_EXCEPTIONS" ]
    }]
}

// please don't submit that on your PR though, this would only work locally to you

I've followed the cmake build steps in simdjson's repository, have built the dll, copied it in simdjson_nodejs folder and referenced it in the new binding.gyp. Here are the results

C:\simdjson> cmake -DCMAKE_GENERATOR_PLATFORM=x64 -DSIMDJSON_BUILD_STATIC=OFF -DCMAKE_GENERATOR_TOOLSET="v141" -DCMAKE_VS_PLATFORM_TOOLSET="v141"
CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.

So yeah, it turns out that the main issue here (despite my recently updated Visual Studio Build Tools 2017 for latest node-gyp) is that my workstation processor (AMD A8 6XXX) does not support AVX2 instructions.

Long story short, the following must be in check:

Thanks @luizperes for your time and support!
