NodeJS By Examples

Compiling NodeJS from the source

0. Check Node distribution: http://nodejs.org/dist/

1. # cd /usr/src

2. Grab the latest:  # wget http://nodejs.org/dist/node-latest.tar.gz

3. Untar:   # tar tar zxf node-latest.tar.gz

4. # cd node-v0.12.00

5. # ./configure

6. # make

7. # make install

8. # /usr/local/bin/node -v   or just #node -v 

        v0.12.0

9. # npm -v

    2.5.1

 

10. #npm list -g

SYMBOLIC LINKS

We don't have to create symbolic links to /usr/bin/ directory beacuse commands #node and #npm works without symbolic linking.

 

ENVIRONMENT VARIABLE

Set NODE_PATH environment variable. Otherwise NodeJS Apps will not be able to load global modules!

#export NODE_PATH=/usr/local/include/node:/usr/local/lib/node_modules

 

INSTALLATION DIRECTORY PATHS

NodeJS is installed into:

/usr/local/include/node/    - node API javascript library

/usr/local/bin/node      - node executable binary file

 

NPM is installed into:

/usr/local/lib/node_modules/         - node modules

/usr/local/bin/npm          -npm binary file

 

Now when we install module globally it will go into /usr/local/lib/node_modules/ for example  # npm install -g express .
