##Developing

to set up build tools make sure you have node installed and run `npm install`

to set up build tools make sure you have node and grunt-cli installed and then run `npm install`



to build run `grunt` if that doesn't work try:

to do the complete build and browser tests run



```bash

npm install -g grunt-cli #you may need a sudo in front of that

grunt

```



to run node tests run



```bash

npm test

```



to run node tests with coverage run



```bash

node test --coverage

```



to create a build with only default projections (latlon and Mercator) run 



```bash

grunt build

```



to create a build with only custom projections include a comma separated list of projections codes (the file name in 'lib/projections' without the '.js') after a colon, e.g.



```bash

grunt build:tmerc

#includes transverse Mercator

grunt build:lcc

#includes lambert conformal conic

grunt build:omerc,moll

#includes oblique Mercator and Mollweide

```
