Contributing to nativescript-vue

If you feel like contributing to this project, that is awesome! This guide should help you get started.

Pull Request Guidelines

It's OK to submit PR against the master branch
It's OK to have multiple commits per PR (will be squashed during merge)
Please describe the changes in every PR, to make it easier to review. (No empty PR descriptions please)

We will re-iterate these guidelines as the project matures.

Contributing to docs

Refer to the nativescript-vue/nativescript-vue.org repository

Development setup

You will need Node.js installed, as well as NativeScript.

Please make sure you are using Nativescript 4.x

After cloning the repo, run:

npm install

(inside the nativescript-vue folder)

Commonly used NPM scripts

$ # watch and auto re-build dist/index.js
$ npm run dev

Testing with the sample application(s)

To test the sample applications provided in the repository, you need to npm run dev in the root directory. This will watch for changes, and rebuild nativescript-vue, which in dev mode will be generated into the samples/app directory (this has been done to reduce the required steps of linking local packages, which had many issues with the recent releases of npm).

Next, open up a new terminal window and run npm run samples. This will bring up a list of all the available sample applications which you can choose from with your arrow keys. Pressing enter/return will select that sample, and prompt you to choose the platform you'd like to run the sample on. After selecting the platform the application should start on your emulator, and the output will be in your terminal.

If you want to test the sample apps with HMR activated, please run npm run samples -- --hmr instead. Actually, we can pass any arguments to the tns debug platform command placing them after the -- separator.

Troubleshooting

1. Husky 'binding.open' error

There is [currently] a bug in devDependencies husky 0.15 beta that aborts npm install if .git/hooks is missing.

typicode/husky#195

> husky@0.15.0-rc.3 postinstall /.../nativescript-vue/node_modules/husky
> node lib/installer/bin install
husky > setting up git hooks
fs.js:663
  return binding.open(pathModule.toNamespacedPath(path),
                 ^
Error: ENOENT: no such file or directory, open '/.../nativescript-vue/.git/hooks/applypatch-msg'

Mac:

nativescript-vue$ mkdir -p .git/hooks/

2. Make sure JAVA_HOME is set to your JAVA 8 JDK!

If JAVA_HOME isn't set correctly, then npm run samples will exit back to the command prompt after prompting for a sample and platform.

Mac:

export JAVA_HOME=`/usr/libexec/java_home -v1.8`

3. Deploying to Android on MacOS fails due to a `ENFILE: file table overflow ...` error.

If you see an error like this:

Transferring project files...
Multiple errors were thrown:
ENFILE: file table overflow, open '/Users/tiagoalves/Projects/ns-vue/(...)/file-name-resolver/package.json'

it means you have to increase the file limits (see: http://stackoverflow.com/a/27982223). You can do that with:

echo kern.maxfiles=65536 | sudo tee -a /etc/sysctl.conf
echo kern.maxfilesperproc=65536 | sudo tee -a /etc/sysctl.conf
sudo sysctl -w kern.maxfiles=65536
sudo sysctl -w kern.maxfilesperproc=65536
ulimit -n 65536 65536

4. Using XCode 8

Check if xcodeproj is installed

sudo gem install xcodeproj -v 1.4.1

You may need to enable system ruby (macos)

rvm use system // now using system ruby
repeat sudo gem install xcodeproj -v 1.4.1
tns run ios

You will probably get an error: No profiles for 'org.nativescript.MyApp' were found: Xcode couldn't find a provisioning profile matching 'org.nativescript.MyApp'

Open the project
nav to app/iOS/build.xcconfig
include PROVISIONING_PROFILE = testapp;

Change app.js to

const Vue = require('nativescript-vue');

new Vue({

  data: {
	message: "Hello Vue!"
  },

  template: `
    <Page>
      <StackLayout>
        <Label v-model="message" />
      </StackLayout>
    </Page>
  `,
}).$start()
