SAFE Browser

Notes!

The Safe Browser is actively being developed against various iterations of The Safe Network. Both of which are still considered alpha software, so please be prepared to encounter and report bugs!

You currently (need the Safe Authenticator to be installed.)[https://github.com/maidsafe/safe-api#the-authenticator-daemon].

Known Issues

Currently 404 pages renders are being swallowed by electron (https://github.com/electron/electron/issues/21046), so these errors / pages returned to browser will return a 200 error code, but a 404 page served by the browser's internal server.

About

Built upon peruse, but using its baked in extensibility to add SAFE Network functionality.

Web App Development

Looking for more information about developing websites/web apps for the SAFE Network? Take a look at the Web App Overview.

Installation

For normal SAFE Network browsing, you should download the latest version of the browser from The SAFE Browser releases page.

Application developers should use the same link, but choose the -dev postfixed version for their platform. This version uses a mock network to allow local development (without the need to pay PUT costs on a live SAFE Network).

We use a dev branch for development. And we keep master as a stable reference updated with each release.

Design

To find out more about the structure of Peruse and the SAFE functionality extending it, read the Browser Application Design Overview.

Build

Prerequisites

  • Node.js ^8.0.0 (we recommend installing it via nvm)
  • Git
  • Yarn (as a replacement for npm).
  • Windows-specific:
    • Yarn attempts to build modules concurrently with multiple child processes, which causes intermittent timing issues on Windows. Users need to run yarn config set child-concurrency 1 just once to effect local yarn settings.
    • In order to be able to build native Node modules for this library, run npm install --global --production windows-build-tools which installs Python 2.x, Visual Studio 2015 build tools, and Visual C++ build tools.
  • If you are using Ubuntu, Mint, or Debian 9 as OS, libgconf-2-4 and/or build-essential dependencies might be missing. Please install them as needed with Synaptic Package Mgr., or with apt from a shell console: $ sudo apt-get install libgconf-2-4 build-essential

Build steps

  • git clone https://github.com/maidsafe/safe_browser.git
  • git checkout master (master is the stable branch. dev is current working branch)
  • cd safe_browser
  • NODE_ENV=dev yarn (NODE_ENV is needed to install mock libs and to run yarn mock-dev).
  • yarn rebuild

And to run dev mode:

  • yarn mock-dev

Want to run 'production' variables, but with hot reloading?

  • yarn put-live-net-files-for-<windows|osx|linux>
  • yarn prod-dev

Note, you'll need a crust.config set for the application. Helper commands for osx/linux/windows

And to package:

  • yarn package

The resulting packages are contained within the releases folder.

A packaged application, built in a NODE_ENV=dev, can access either prod or dev networks. prod is the default, or alternatively you can open the application and pass a --mock flag to open and use a mock network.

linux

On Linux, the packaged application gets generated as a Shared Library file and hence cannot be run by double-clicking the executable. This is due to an issue with electron-builder( https://github.com/electron-userland/electron-builder/issues/3950 ). But the application can be run through the terminal. You can run the browser by running ./safe-browser.

macOS

On macOS, the application should be located in the 'Applications' for security reasons. By default the packaged application will prompt to move the application. To override this, you can pass --ignoreAppLocation:

open release/safe-browser-<version>-mac-x64/SAFE\ Browser.app --args --ignoreAppLocation

Development commands

There are a few build commands for various situations:

  • yarn prod-dev will run a developer version of the application using the live network.
  • yarn build compiles all code, but you shouldn't need to use this
  • yarn build-preload will need to be run whenever you change the preload.js file for changes to show up in the browser.

Release

Pushes to master will be automatically released, with changelog generated from conventional commits (enforced at commit time, and checked at CI), and the version bumped autmomatically.

Alpha/Beta Channels

To release alpha/beta versions of the browser, simply create a version tag for the release you want, ie v0.18.0-alpha.0 and push this to the repository to trigger a build of that alpha/beta version.

Testing

  • yarn test runs jest (you have the optional yarn test-watch, too).
  • yarn test-e2e runs spectron integration tests (not yet stable).

Linting

  • yarn lint runs the linter and throws all of the lint errors
  • yarn lint-fix runs the linter, Automatically fix problems that it can & throws the remaining lint errors

Logging

Via electron-log: import { logger } from '$Logger', and you can logger.info('things').

Logs are printed to both render console and stdout. Logs are also written to a log file per system.

yarn log-osx will tail the file. Similar commands (as yet untested) exist for linux/windows.

electron-logis used under the hood, and ouputs logs to:

  • on Linux: ~/.config/safe-browser/logs/{process type}.log
  • on macOS: ~/Library/Logs/Safe Browser/{process type}.log
  • on Windows: %USERPROFILE%\AppData\Roaming\Safe Browser\logs{process type}.log

Further Help

You can discuss development-related questions on the SAFE Dev Forum. If you are just starting to develop an application for the SAFE Network, it's very advisable to visit the SAFE Network Dev Hub where you will find a lot of relevant information, including a tutorial to create an example SAFE web application which makes use of the API exposed by the SAFE Browser.
