Browser Solidity is a browser-based Solidity compiler and IDE.

Visit https://ethereum.github.io/browser-solidity to use; it will always deliver the latest version.

Full offline usage is currently not supported because the compiler is always loaded via http. If you clone/download the repository, use the gh-pages branch (otherwise you still have to build the application).

Many dependencies are only provided via npm:

npm install    # fetch dependencies
npm run build  # build application into build/app.js

Now point your browser to index.html to open the application.

Here are some things to consider if you have trouble building the package.

• Make sure that you have the correct version of node, npm and nvm. You can find the version that is tested on Travis-ci by looking at the log in the build results.

Run:

node --version
npm --version
nvm --version

• In Debian based OSes such as Ubuntu 14.04LTS you may need to run apt-get install build-essential. After installing build-essential run npm rebuild.

Register new unit test files in test/index.js. The tests are written using tape. Run the tests via:

npm test

To run the Selenium tests via nightwatch serve the app through a local web server:

npm run serve # starts web server at localhost:8080

Then you will need to either:

1. Have a Selenium server running locally on port 4444.

• Run: npm run browser-test

1. Or, install and run SauceConnect.

• Run: sc -u <USERNAME> -k <ACCESS_KEY> (see .travis.yml for values)
• Run: npm run browser-test-sc

If you would like to use this as a Chrome extension, you must either build it first or pull from the gh-pages branch, both described above. After that, follow these steps:

• Browse to chrome://extensions/
• Make sure 'Developer mode' has been checked
• Click 'Load unpacked extension...' to pop up a file-selection dialog
• Select your browser-solidity folder
