Install Nitrogen on Mochiweb

DEPRECATED

Now you create a new application using the `nitrogen` command and change ‘inets’ to ‘mochiweb’ in the ebin/myweb.app file.

For more follow the Installing Nitrogen instructions

Nitrogen hooks into Mochiweb through your application’s loop(Req, DocRoot) function.

1. Download and build Mochiweb.

• Download Mochiweb to a directory called MOCHIWEB_ROOT.
• Under MOCHIWEB_ROOT run ‘make’.

2. Download Nitrogen and build Nitrogen

• Download Nitrogen to a directory called NITROGEN_ROOT
• Under NITROGEN_ROOT run ‘make’.

3. Make a new Mochiweb Application.

• Under MOCHIWEB_ROOT, run: chmod +x scripts/new_mochiweb.erl; ./scripts/new_mochiweb.erl nitrogen_demo ..

4. Copy the Nitrogen Web Files

Nitrogen needs the files under NITROGEN_ROOT/www to run. Copy these files to a nitrogen directory under …/nitrogen_demo/priv/www

mkdir ../nitrogen_demo/priv/www/nitrogen; cp NITROGEN_ROOT/www/* ../nitrogen_demo/priv/www/nitrogen

- or -

ln -s NITROGEN_ROOT/www ../nitrogen_demo/priv/www/nitrogen

- or on windows -

download and install the junction.exe command into your windows/system32 directory from http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx

junction ../nitrogen_demo/priv/www/nitrogen NITROGEN_ROOT/www

The goal is to have these files served under http://localhost:8000/nitrogen

5. Set up wf_global

• Copy NITROGEN_ROOT/Quickstart/src/wf_global.erl to the nitrogen_demo/src directory.
• Edit wf_global.erl, replace the signkey with a unique signkey that only you know. Nitrogen uses this value to uniquely sign data that it sends to the browser.
• Compile wf_global.erl

6. Add nitrogen to the deps folder

ln -s NITROGEN_ROOT ../nitrogen_demo/deps/nitrogen

- or on windows -

junction ../nitrogen_demo/deps/nitrogen NITROGEN_ROOT

7. Update your main Mochiweb loop.

• Edit ../nitrogen_demo/src/nitrogen_demo_web.erl, and in loop/2:
• Add a call to wf:init() as the first line in the function.
• Look for the two case Path of statements.
• Add a clause to each one saying: "web/" ++ _ -> wf_mochiweb:loop(Req);

8. Make nitrogen_demo

cd nitrogen_demo; make

9. Start your Application

Run start-dev.sh, and navigate to http://localhost:8000/web/test
Congratulations, you have now successfully run your first Nitrogen application.
