Wibson is a blockchain-based, decentralized data marketplace that provides individuals a way to securely and anonymously sell validated private information in a trusted environment.

buyer-sdk is the implementation of the official SDK to play as a Buyer in Wibson Protocol.

This repository contains three applications:

• Buyer APP: Front-end App for the Buyer.
• Buyer API: Service consumed by the Buyer APP.
• Buyer Signing Service: Service used to sign the transactions sent to the Ethereum Network, consumed by Buyer API.

Secrets Management

Encrypting .env file

gpg -e -a .env

Editing .env file securely

mv .vimrc.example ~/.vimrc
vi .env.asc

Exporting GnuPG private key

gpg --export-secret-keys -a -o private-key.asc <key-id>

Running app with encrypted .env

GPG_KEY_PATH="private-key.asc" ENV_PATH=".env.asc" npm run start

Executing tasks by command line

Tasks can be executed by running the following commands

Development

$ npm run task:dev                     # displays available tasks in src directory
$ npm run task:dev -- <task-name>      # executes <task-name> from src directory

Production

$ npm run task                         # displays available tasks in dist directory
$ npm run task -- <task-name>          # executes <task-name> from dist directory

Using Subdirectories

It supports subdirectories, in which case the command will be:

$ npm run task -- <subdirectory>:<file-name-without-.js>

Example:

$ npm run task -- migrations:batpay-balance

Defining new command line tasks

In order to define a new task to be run by command line, a JS file should be created under the src/tasks directory.

It can be placed under a subdirectory like src/tasks/migrations.

Last but not least, the file should export by default a function which can be async OR an object with several async functions.
