Remix is a browser-based compiler and IDE that enables users to build Ethereum contracts with Solidity language and to debug transactions.
To try it out, visit https://remix.ethereum.org.
https://github.com/ethereum/remix-ide/releases also gives others ways to use Remix locally. Please check it out.
Remix consists of many modules and in this repository you will find the Remix IDE (aka. Browser-Solidity).
gh-pages branch has always the latest stable build
of Remix. It also contains a ZIP file with the entire build. Download it
to use offline.
Note: it contains the latest release of Solidity available at the time of the packaging. No other compiler versions are supported.
Install npm and node.js (see https://docs.npmjs.com/getting-started/installing-node), then do:
Remix-ide has been published as an npm module:
npm install remix-ide -g remix-ide
Or if you want to clone the github repository (
wget need to be installed first) :
git clone https://github.com/ethereum/remix-ide.git git clone https://github.com/ethereum/remix.git # only if you plan to link remix and remix-ide repositories and develop on it. cd remix # only if you plan to link remix and remix-ide repositories and develop on it. npm install # only if you plan to link remix and remix-ide repositories and develop on it. npm run bootstrap # only if you plan to link remix and remix-ide repositories and develop on it. cd remix-ide npm install npm run setupremix # only if you plan to link remix and remix-ide repositories and develop on it. npm start
npm start and open
http://127.0.0.1:8080 in your browser.
Then open your
text editor and start developing.
The browser will automatically refresh when files are saved.
Most of the the time working with other modules (like debugger etc.) hosted in the Remix repository is not needed.
Some things to consider if you have trouble building the package:
- Make sure that you have the correct version of
nvm. You can find the version that is tested on Travis CI by looking at the log in the build results.
node --version npm --version nvm --version
- In Debian based OS such as Ubuntu 14.04LTS you may need to run
apt-get install build-essential. After installing
Register new unit test files in
The tests are written using tape.
Run the unit tests via:
For local headless browser tests run
npm run test-browser
(requires Selenium to be installed – can be done with
npm run selenium-install)
Running unit tests via
npm test requires at least node v7.0.0
To run the Selenium tests via Nightwatch:
Build Remix IDE and serve it:
npm run build && npm run serve# starts web server at localhost:8080
Make sure Selenium is installed
npm run selenium-install# don’t need to repeat
Run a selenium server
npm run selenium
Run all the tests
npm run nightwatch_local_firefoxor
npm run nightwatch_local_chrome
Or run a specific test case:
- npm run nightwatch_local_ballot - npm run nightwatch_local_libraryDeployment - npm run nightwatch_local_solidityImport - npm run nightwatch_local_recorder - npm run nightwatch_local_transactionExecution - npm run nightwatch_local_staticAnalysis - npm run nightwatch_local_signingMessage- npm run nightwatch_local_console - npm run nightwatch_local_remixd # remixd needs to be run
Usage as a Chrome Extension
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
- Make sure ‘Developer mode’ has been checked
- Click ‘Load unpacked extension…’ to pop up a file-selection dialog
- Select your
