fh-fhc

FHC - FeedHenry Command Line Interface NPM version

FeedHenry CLI, the command line interface to FeedHenry.

Installation

fhc should now be available your command line.
fhc -v will tell you what version of fhc you have installed.

Finally, install FHC bash completion: fhc completion >> ~/.bashrc (or ~/.zshrc)

Usage

From the Command Line

To see the list of commands available, just run fhc.
See fhc help for general help, or fhc help <someCommand> for help on a specific command.

To get started with fhc, set the FeedHenry target and then login:

$ fhc target https://apps.feedhenry.com

$ fhc login <your-email-address> <your-password>

To list your projects, use:

$ fhc projects

To create an app from a git repository use:

fhc app create --project=SomeProjectId --title=WelcomeApp --type=cloud_nodejs git://github.com/feedhenry-templates/welcome-app.git

As a Node.js Module

You can also use fh-fhc as a Node.js module in your scripts. This is useful for scripting automated tests, mobile app client builds and cloud deploys.

First, install & add it to your project dependencies by doing npm install --save fh-fhc from your project root.
Then, you can require it in your code like so:

var fhc = require('./lib/fhc');
fhc.load(function(err) {
  if (err) {
    // Something went wrong
  }
  // FHC started up OK - we can now perform commands, like listing projects:
  fhc.projects({_ : []}, function(err, projects) {
    if (err) {
      // Handle error
    }
    console.log(projects);
  });
});

Some commands require params to be passed in - these are typically passed like so:

fhc.app.create({ title : 'Some title', project : 'someProjectId'}, function() {
});

Older fhc commands still pass arguments in an ordered array, as below. The environment is still specified outside the array.

fhc.app.logs({_ : ['projectId', 'appId'], env : 'dev' }, function() {
});

Observation : The older commands have been changed to work as the new ones. In the future, all commands should work without the need to pass the params in an ordered array.

From Docker

To use FHC via docker, run commands like:

$ docker run -v $HOME:/root -it feedhenry/fhc target https://rhmap.cup.feedhenry.io

We mount $HOME into the the container to persist configuration in ~/.fhcrc & ~/.fhctargets on the host. You may want to alias this docker run command to fhc, by adding an alias to your shell's config:

alias fhc='docker run -v $HOME:/root -it feedhenry/fhc'

Now you'll be able to run commands similar to:

fhc target https://rhmap.cup.feedhenry.io

Building & Releasing for Docker

To build:

$ docker build -t feedhenry/fhc .

Get your Image ID via:

$ docker images | grep fhc
feedhenry/fhc          latest              0618027d8d57        8 minutes ago       749 MB

Tag this as latest & the version in package.json:

$ docker tag 0618027d8d57 feedhenry/fhc:latest
$ docker tag 0618027d8d57 feedhenry/fhc:2.17.3

Push your images (you may need to login):

$ docker push feedhenry/fhc

Finally, verify your push by visiting:

https://hub.docker.com/r/feedhenry/fhc/tags/

Extending

Version 1.0 of fh-fhc updates the structure of commands:

lib
  cmd # all commands go here
    common # stuff which applies to both versions of feedhenry
    fh2    # feedhenry 2-specific commands go here (e.g. `account`)
    fh3    # feedhenry 3 specific commands go here (e.g. `project`)
  internal # internal piping goes here

The common, fh2 and fh3 directory structure doesn't get exposed to the user, but everything underneath does - meaning we can have a command lib/cmd/common/fooGroup/barCommand.js, another lib/cmd/common/fh3/fooGroup/anotherCommand.js, and be able to run both fhc fooGroup barCommand and fhc fooGroup anotherCommand.
Internal commands in the internal directory are hidden from help output, but are still call-able.

Writing new commands is a little different than before. Old commands export a function - new style commands export an object.

Commands are DRY'd up substantially - see App List lib/cmd/fh3/app/list.js as an example of what a command definition looks like. Using the 'demand' syntax, yargs look after all all validation - you don't need to worry about it. Commands can be DRY'd up even more if they're very similar - e.g. app start. This extends from a base class - anything with an _ prefix doesn't go into the command tree.

There's no longer need to require() new commands in many different places - no need to require() new commands at all, just put them in the relevant tree structure within in lib/cmd. Tests are turbo'd, nock for mocks, coverage is at least a little better than before.

Setting a Proxy Server

fhc fhcfg set proxy http://host:port
# eg:
fhc fhcfg set proxy http://127.0.0.1:8080

Tests

grunt test

Internationalization

all of the strings expecting to be internationalized has to be passed through i18n._() function like:

module.exports = {
  'desc': i18n._('Version info about the FeedHenry instance we\'re connected to'),
  ...
}

To get strings translated, we use the Zanata, the web-based translation platform. the source strings file has to be uploaded into the Zanata server. that can be done with:

grunt potupload

Prior to do that, please make sure you have an account on the Zanata server. if not, please visit https://translate.zanata.org and follow up the steps at http://docs.zanata.org/en/release/user-guide/account/account-sign-up/ to create an account, and http://zanata-client.readthedocs.io/en/latest/configuration/ to store the API key into $HOME/.config/zanata.ini.

Node version :

FHC requires node 4.4.x version

Javascript style & syntax

Javascript style & syntax can be checked using:

grunt eslint
  • eslint configuration is in .eslintrc.json
  • If eslint has any errors, the build will fail

Report Bug/Issue:

RHMAP Supportability

If you are targetting a version of RHMAP < 3.5.0 then install an older version of fh-fhc with npm install fh-fhc@latest-1.
