"Send on Facebook Messenger" command for Alfred.app.

_README.md

Send on Messenger

Usage

Assumes you have node.js and npm.

Once, on install

Create a file ~/.facebook-auth containing your login email and password in the format me@example.com:my-password.

E.g.

echo "me@example.com:my-password" > ~/.facebook-auth

Install dependencies:

npm install

Run it manually

./send.js "Mark Zuckerberg" "Hello there"

Integrate it with Alfred.app

Make a workflow (left as an exercise to the reader) e.g. "im my message" to send "my message" to your favourite person.

In the "Run Script" action of that workflow, have it do something like:

/usr/local/bin/node /Users/henrik/Dropbox/send_on_messenger/send.js "Mark Zuckerberg" "{query}" > /tmp/fb.log 2> /tmp/fb.error.log
