Remixd is a tool that intend to be used with Remix IDE (aka. Browser-Solidity). It allows a websocket connection between
Remix IDE (web application) and the local computer.
Practically Remix IDE make available a folder shared by Remixd.
More details are explained in this tutorial.
Alternatively Remixd can be used to setup a development environment that can be used with other popular frameworks like Embark, Truffle, Ganache, etc..
npm install -g remixd
Usage: remixd -s <shared folder> Provide a two ways connection between the local computer and Remix IDE. Options: -s, --shared-folder <path> Folder to share with Remix IDE -m, --mist start mist -g, --geth start geth -p, --dev-path <dev-path> Folder used by mist/geth to start the development instance -f, --frontend <front-end> Folder that should be served by remixd -p, --frontend-port <front-end-port> Http port used by the frontend (default 8082) -a, --auto-mine mine pending transactions -r, --rpc <cors-domains> start rpc server. Values are CORS domain -rp, --rpc-port rpc server port (default 8545) -h, --help output usage information
SHARE A FOLDER
remixd -s <absolute-path>
The current user should have
read/write access to the folder (at least
It is important to notice that changes made to the current file in
Remix IDE are automatically saved to the local computer every 5000 ms. There is no
Save action. But the
Ctrl-Z (undo) can be used.
- No copy of the shared folder are kept in the browser storage.
- It is not possible to create a file from
Remix IDE(that might change).
- If a folder does not contain any file, the folder will not be displayed in the explorer (that might change).
- Symbolic links are not forwarded to Remix IDE.
START GETH, MIST and setup a development environment
Remix allows to start a dev environment.
Geth is used to spawn a dev blockchain and
Mist to provide an user interface to interact with dapps in development and Remix IDE (It is also possible to use
Metamask and a normal browser)
Geth are not shipped with Remixd.
Mist at https://github.com/ethereum/mist/releases
Geth at https://ethereum.github.io/go-ethereum/downloads
remixd --dev-path /home/devchains/chain1 --mist --geth --frontend /home/frontend --frontend-port 8084 --auto-mine
- create a new data folder (
dev-pathoption) if it doesn't exist containing blockchain data and keys.
- serve a local folder through an http server (
frontend-portoption). This option may be used if you want to browse your dapp using
Mistor a normal browser and
Metamask(see third example) (https://metamask.io). In this example the web application located at
/home/frontendwill be available at http://127.0.0.1:8084
- start to mine automatically when new transactions are created.
remixd -s /home/user/project1/contracts
- allow accessing the local folder from Remix IDE (http://remix.ethereum.org)
remixd --dev-path /home/devchains/chain1 --rpc --rpc-port 8545 --geth --frontend /home/frontend --frontend-port 8084 --auto-mine
- do the same as the first example but do not start
Mist. It is still possible to browse a front end app using a normal browser and
Metamask. The connection between Metamask and
gethhas to be done via rpc connection and thus the rpc server has to be enabled (
Note that in that case Remix IDE (remix.ethereum.org) does not need Metamask. It is possible to use the
Web3 Provider option of Remix to connect to the
Geth RPC endpoints.
