npm2nix's Issues

Generates incorrect default.nix for iojs

When using iojs the generated default.nix should be slightly different, for example:

{ foo ? { outPath = ./.; name = "foo"; }
, pkgs ? import <nixpkgs> {}
}:
let
  nodePackages = import "${pkgs.path}/pkgs/top-level/node-packages.nix" {
    inherit pkgs;
    inherit (pkgs) stdenv fetchurl fetchgit;
    nodejs = iojs;
    neededNatives = [ pkgs.python ] ++ pkgs.lib.optional pkgs.stdenv.isLinux pkgs.utillinux;
    self = nodePackages;
    generated = ./packages.nix;
  };
in rec {
  tarball = pkgs.runCommand "foo.tgz" { buildInputs = [ pkgs.iojs ]; } ''
    mv `HOME=$PWD npm pack ${foo}` $out
  '';
  build = nodePackages.buildNodePackage {
    name = "foo";
    src = [ tarball ];
    buildInputs = nodePackages.nativeDeps."foo" or [];
    deps = [];
    peerDependencies = [];
  };
}

#tree references not working

I'm trying to package gitbooks which contains:

        "nunjucks": "mozilla/nunjucks#103513c294835bcbe64222de6db494e2555e294e",

which fails with

Any ideas how to fix? I'm not familiar with npm at all.

Status of the repository?

Hi,

As part of NixOS/teams-collaboration#1, I am trying to clarify the status of the repositories under the NixOS organisation.

This repository seems to be unmaintained or obsolete, so it will be archived in a month.

If you think it warrants staying here or should be moved to another organization instead, please answer this issue.

A more stable method of retrieving package information

In #21 there was a discussion about an alternative method of retrieving package information.

At the moment npm and node change quite often, as do their file structures. Relying on the structure of package.json is therefore often errorprone.

If we could reuse npm to do as much as possible, we could circumvent this problem. It might be somewhat less efficient compared to the current implementation, but since npm2nix is usually not run daily, this does not matter much.

I created this issue to focus on reusing npm and gather all the necessairy bits needed to get to an implementation of npm2nix.

npm install creates node_modules with all dependencies of package.json installed.
npm ls --json shows a recursive list in JSON of all packages and their dependencies.
Tarballs from npmjs: The cache that is normally in ~/.npm/{packageName}/{packageVersion}/package.tgz can be used to generate hashes for the .tgz files. Alternatively, we can use the shasum from npmjs registry.
We can make npm use a different cache directory so that it doesn't download files into $HOME.
Tarball URLs: I'm not sure these are placed in ~/.npm/
Git URLs: We need a way to hash these. The current method in npm2nix could be used, but it is desirable to let npm retrieve the git repo.
Custom URLs: github: and probably others will be used as dependencies in the near future. We need to get npm to download these as git repos, so that we can hash them.
Handle directory structure for github: URLs.

The devDependencies are ignored

Currently npm2nix package.json package.nix creates a default.nix that adds packages under devDependencies to deps. Everything listed in packages.json under devDependencies is ignored.

Update package on npm

I don't know who has access to npm. I currently maintain all node stuff, so i would need a new release. Currently git release is used in nixpkgs.

Error in handling some git dependencies

The npm itself installs the package without issues

git rev-parse's stdout ended before 64 characters were read

Hi, npm2nix seems to be failing on the jsbn module, perhaps because it's a git repo type module, but I'm not sure.

git clone [email protected]:NixOS/npm2nix.git
cd npm2nix
nix-shell
rm -rf ~/.npm
node --version > output.txt
git --version >> output.txt
node lib/command.js package.json node-packages-generated.nix >> output.txt 2>&1

Result: output.txt

...

Cheers

generated file is incomplete

I'm running npm2nix on my package.json and it finishes without errors, but I'm getting a file that looks like this :

{ self, fetchurl, fetchgit ? null, lib }:

{

I have node v0.12.2 and npm2nix 5.8.1 installed.

Disable npm user config

A user's ~/.npmrc might have, for example, a different registry URL, which could end up generating the wrong package set. This behavior can be disabled manually with npm_config_userconfig=/dev/null npm2nix [...], but it'd be nicer not to need to remember.

Problem of "postinstall"

Hello !

I've been starting with Nix for few days now, and was particularly interested in using it to handle JS dependencies (I really like the philosophy behind it 😃).

IMHO, one of the major problem with npm is the existence of postinstall... I've encountered several packages (like jpegtran-bin or phantomjs if I remember well, which are simply wrappers to download the appropriate binary).

I just made the test with the jpegtran-bin package and the output concerning this package is :

  by-spec."jpegtran-bin"."^3.0.0" =
    self.by-version."jpegtran-bin"."3.0.6";
  by-version."jpegtran-bin"."3.0.6" = self.buildNodePackage {
    name = "jpegtran-bin-3.0.6";
    version = "3.0.6";
    bin = true;
    src = fetchurl {
      url = "https://registry.npmjs.org/jpegtran-bin/-/jpegtran-bin-3.0.6.tgz";
      name = "jpegtran-bin-3.0.6.tgz";
      sha1 = "d266af271a7603046984fd31c3c2503407b92323";
    };
    deps = {
      "bin-build-2.2.0" = self.by-version."bin-build"."2.2.0";
      "bin-wrapper-3.0.2" = self.by-version."bin-wrapper"."3.0.2";
      "logalot-2.1.0" = self.by-version."logalot"."2.1.0";
    };
    optionalDependencies = {
    };
    peerDependencies = [];
    os = [ ];
    cpu = [ ];
  };

It may be a naive question but do you think it would be feasible to support postinstall option ?

Invalid default.nix for packages with special characters

In some rare cases when packages have dot(.) in their names, npm2nix generates invalid default.nix.

For example:
https://raw.githubusercontent.com/isagalaev/highlight.js/master/package.json

{ highlight.js ? { outPath = ./.; name = "highlight.js"; } ...

error: syntax error, unexpected '?', expecting '.' or '=', at "/tmp/tmp.hz1BdxeD8N/default.nix":1:16

npm-registry-client 0.2.27 can't handle scoped packages.

At the (very old!) version of npm-registry-client used by npm2nix, URIs are unconditionally uriencoded: https://github.com/npm/npm-registry-client/blob/v0.2.27/lib/request.js#L56

Node packages in nixpkgs cannot be updated currently due to cyclic dependency.

Example json:
[ "d" ]

d depends on es5-ext, which depends on es6-iterator, which depends on both d and es5-ext

Relative file paths in package.json are treated as github URLs

Using node 0.12.0.

When you have a dependency list like the following:

"dependencies": {
  "mymodule": "./node_modules/mymodule",
  "jquery": "~1.11.1",
},

You get an error like this:

Error during fetch: Error fetching git://github.com/./node_modules/mymodule from git: Error executing git clone: Error: spawn git ENOENT

Have also tried with the following:

"dependencies": {
  "mymodule": "file:./node_modules/mymodule",
  "jquery": "~1.11.1",
},

produces empty file with node v0.12.0

Thats the result with node v0.12.0

{ self, fetchurl, fetchgit ? null, lib }:

{%

Update license and package.json author field

I will not be the primary author on npm2nix moving forward, so probably the copyright notice and package.json should reflect that.

Handle the "os" attribute

See https://www.npmjs.org/doc/files/package.json.html#os , npm2nix should set platforms appropriately.

handle deps with git+ssh locations

I have a project which uses several private modules which are not on npms but just git repos. So npm2nix will fail with something like :

building path(s) ‘/nix/store/z0dnfrb0riii8mgzg9k7mdfh3i7gpgbq-healthcheck-middleware-e288c34’

Can this be supported at all ? And if not could you provide some info on a possible workaround for this scenario ?

Support npm-shrinkwrap.json (hapi-7.5.3)

The package hapi-7.5.3 has a file named npm-shrinkwrap.json at the top-level, this file seems to pin the dependencies to specific versions, even if they are out-dated.

While building with nix-build, npm install makes multiple request to example.com to fetch different version than the latest, and finally fails at parsing HTML as a valid JSON file.

A temporary work-around consist at removing the file $PWD/npm-shrinkwrap.json at the end of the configurePhase of buildNodePackage expression.

Cannot rebuild nix-packages-generated.nix

Using nixos-unstable and npm2nix 5.12.0, I cannot rebuild nix-packages-generated.nix:

npm2nix pkgs/top-level/node-packages.json pkgs/top-level/node-packages-generated.nix

Gives me the error:

Error during fetch: Error fetching git://github.com/NixOS/npm2nix.git#5.12.0 from git: git rev-parse's stdout ended before 64 characters were read
error: could not lock config file /tmp/npm2nix-git-checkout-kibana-authentication-proxy11634-1738-1u8vxp1/kibana-authentication-proxy/.git/modules/kibana/config: No such file or directory
fatal: Could not set 'remote.origin.fetch' to '+refs/heads/*:refs/remotes/origin/*'
fatal: clone of 'https://github.com/elasticsearch/kibana.git' into submodule path 'kibana' failed

This is the first time I'm using npm2nix, so I might very well do something completely wrong.

scoped packages still fail

Just tried to apply npm2nix on Abricotine.

May it be, that npm2nix has troubles with that @ in the dependency name?

npm2nix package.json default.nix
...
Error during fetch: Could not find version matching ^0.9.2 for @shagstrom/split-pane in undefined

Handle optionalDependencies

See https://www.npmjs.org/doc/files/package.json.html#optionaldependencies . Especially usefuil if #6 is implemented, as there may be some dependency that can't be provided on a given platform.

ETIMEDOUT and ECONNRESET

I'm trying to update node-packages-generated.nix in nixpkgs, after working for minutes sometimes it gets stuck in ETIMEDOUT or ECONNRESET errors.
Perhaps the concurrency at which it downloads info from registry is too high? Is it possible to change it?

"not a valid repository name" error

I'm getting this error while generating a package

fatal: remote error:
github:matrix-org/react-gemini-scrollbar is not a valid repository name

The problem appears to be related to the github URL scheme.
ssbc/patchwork#458 mentions old npm versions as a cause but I have version 3.10 which should support it.

Do you have any queue ?

Regards.

There is no `file` variable

Thus, it crashes.

Yay for dynamically typed languages

Make clear that this project is unmaintained

It seems to be unmaintained and the widely endorsed replacement is node2nix. It would probably be good to make that clear in the readme so newcomers don't spend time on something that very few people still use.

Can't process git dependency by commit SHA

package.json:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

HEAD is now at 4c77f46... add fcntl to README.md

The error message seems to be coming from git rev-parse, while the warning about the detached HEAD state seems to be from a (successful) git checkout of the given commit.

I tried downgrading to version 5.6.0 of npm2nix, and that seems to work for the same package.json

npm pack doesn't work on optimised store

I'm having problems with the default.nix created by npm2nix - when I'm running it on a system with auto-optimise-store = true, it fails when unpacking sources:

these derivations will be built:

The same command runs fine after setting auto-optimise-store = false (and rebuilding the .tgz).
