Daedalus

Daedalus - cryptocurrency wallet

Automated build

CI/dev build scripts

Platform-specific build scripts facilitate building Daedalus the way it is built by the IOHK CI:

Linux/macOS

This script requires Nix, (optionally) configured with the IOHK binary cache.

scripts/build-installer-unix.sh [OPTIONS..]

The result can be found at installers/csl-daedalus/daedalus-*.pkg.

Pure Nix installer build

This will use nix to build a Linux installer. Using the IOHK binary cache will speed things up.

nix build -f ./release.nix mainnet.installer

The result can be found at ./result/daedalus-*.bin.

Development

shell.nix provides a way to load a shell with all the correct versions of all the required dependencies for development.

Connect to staging cluster:

Start the nix-shell with staging environment yarn nix:staging
Within the nix-shell run any command like yarn dev

Connect to Local Demo Cluster:

Build and Run cardano-sl Demo Cluster

Install nix: curl https://nixos.org/nix/install | sh

Employ the signed IOHK binary cache:

$ sudo mkdir -p /etc/nix
$ sudo vi /etc/nix/nix.conf       # ..or any other editor, if you prefer

and then add the following lines:

substituters = https://hydra.iohk.io https://cache.nixos.org/
trusted-substituters =
trusted-public-keys = hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=

Build and run demo cluster: scripts/launch/demo-nix.sh

Start Daedalus Using Demo Cluster

Start local cardano-sl demo cluster (./scripts/launch/demo-nix.sh)
Inspect the terminal output of cardano-sl and copy the timestamp from the message system start: 1537184804
Start the nix-shell with development environment yarn nix:dev 1537184804 (timestamp is different each time you restart the cardano-sl demo cluster)
Within the nix-shell run any command like yarn dev

"Frontend only" mode

The frontendOnlyMode makes it possible to connect to manually started instances of cardano-node for advanced debugging purposes.

How to connect:

Within the cardano-sl repository, build a script for a certain network. E.g. for testnet: nix-build -A connectScripts.testnet.wallet -o launch_testnet
Launch this cluster + node with ./launch_testnet
You should now have a state-wallet-testnet folder inside the cardano-sl repo. Copy the full path to the sub folder tls in there.
Within the Daedalus repo checkout this branch and run: CARDANO_TLS_PATH=/path/to/tls CARDANO_HOST=localhost CARDANO_PORT=8090 nix-shell

Now you should have a pre-configured nix-shell session where you can yarn dev as usual and Daedalus connects itself to the manually started cardano node.

Parameters:

Param	Mandatory	Default
`CARDANO_TLS_PATH`	Yes
`CARDANO_HOST`	No	`localhost`
`CARDANO_PORT`	No	`8090`

So if you just start the default cardano node (which runs on localhost:8090) you can also start nix-shell with CARDANO_TLS_PATH=/path/to/tls nix-shell

Notes:

shell.nix also provides a script for updating yarn.lock. Run nix-shell -A fixYarnLock to update yarn.lock file.

Configuring the Network

There are three different network options you can run Daedalus in: mainnet, testnet and development (default). To set desired network option use NETWORK environment variable:

$ export NETWORK=testnet
$ yarn dev

Cardano Wallet API documentation

While running Daedalus in development mode you can access Cardano Wallet API documentation on the following URL: https://localhost:8091/docs/v1/index/.

Testing

You can find more details regarding tests setup within Running Daedalus acceptance tests README file.

Notes: Be aware that only a single Daedalus instance can run per state directory. So you have to exit any development instances before running tests!

Wallet fault injection

General information about wallet fault injection can be found in the Cardano's wallet-new README file.

shell.nix has support for passing the necessary flags:

--arg allowFaultInjection true is necessary to enable any processing of faults, and
--arg walletExtraArgs '[ "--somefault" ]' can be used for enabling certain fault types at startup.

Windows

This batch file requires Node.js and 7zip.

scripts/build-installer-win64.bat

The result will can be found at .\daedalus-*.exe.

CSS Modules

This boilerplate out of the box is configured to use css-modules.

All .css file extensions will use css-modules unless it has .global.css.

If you need global styles, stylesheets with .global.css will not go through the css-modules loader. e.g. app.global.css

Externals

If you use any 3rd party libraries which can't or won't be built with webpack, you must list them in your webpack.config.base.js：

externals: [
  // put your node 3rd party libraries which can't be built with webpack here (mysql, mongodb, and so on..)
]

For a common example, to install Bootstrap, yarn install --save bootstrap and link them in the head of app.html

<link rel="stylesheet" href="../node_modules/bootstrap/dist/css/bootstrap.css" />
<link rel="image/svg+xml" href="../node_modules/bootstrap/dist/fonts/glyphicons-halflings-regular.eot" />
...

Make sure to list bootstrap in externals in webpack.config.base.js or the app won't include them in the package:

externals: ['bootstrap']

Packaging

$ yarn run package

To package apps for all platforms:

$ yarn run package:all

To package apps with options:

$ yarn run package -- --[option]

Options

--name, -n: Application name (default: ElectronReact)
--version, -v: Electron version (default: latest version)
--asar, -a: asar support (default: false)
--icon, -i: Application icon
--all: pack for all platforms

Use electron-packager to pack your app with --all options for darwin (osx), linux and win32 (windows) platform. After build, you will find them in release folder. Otherwise, you will only find one for your os.
