About Investbrain
Investbrain helps you manage and track the performance of your investments.
Under the hood
Investbrain is a Laravel PHP web application that leverages Livewire, Mary UI, and Tailwind for its frontend. Most databases should work, including MySQL and SQLite. Out of the box, we feature two market data providers: Yahoo Finance and Alpha Vantage. But we also offer an extensible market data provider interface for intrepid developers to create their own! Finally, of course we have robust support for i18n, a11y, and dark mode.
Installation
For ease of installation, we highly recommend installing Investbrain using the provided Docker Compose file, which downloads all the necessary dependencies and seamlessly builds everything you need to get started quickly!
Before getting started, you should already have the following installed on your machine: Docker Engine, Git, and a wild sense of adventure.
Ready? Let's get started!
First, you can clone this repository:
git clone https://github.com/investbrainapp/investbrain.git && cd investbrain
Then, build the Docker image and bring up the container (this will take a few minutes):
docker compose up
In the previous step, all of the default configurations are set automatically. This includes creating a .env file and setting the required Laravel APP_KEY.
If everything worked as expected, you should now be able to access Investbrain in the browser at:
http://localhost:8000/register
Congrats! You've just installed Investbrain!
Configuration (optional)
There are several configurations available when installing using the recommended Docker method. These options are configurable using an environment file. Changes can be made in your .env file before installation.
| Option | Description | Default |
|---|---|---|
| APP_URL | The URL where your Investbrain installation will be accessible | http://localhost |
| APP_PORT | The HTTP port exposed by the NGINX container | 8000 |
| DB_HOST | The location of your database host where Investbrain is installed | investbrain-mysql |
| DB_DATABASE | The name of the database where Investbrain is installed | investbrain |
| DB_USERNAME | Your database username | investbrain |
| DB_PASSWORD | Your database password | investbrain |
| MARKET_DATA_PROVIDER | The market data provider to use (either yahoo or alphavantage) |
yahoo |
| MARKET_DATA_REFRESH | Cadence to refresh market data in minutes | 30 |
| ALPHAVANTAGE_API_KEY | If using the Alpha Vantage provider | null |
Note: These options affect the docker-compose.yml file, so if you decide to make any changes to these default configurations, you'll have to restart the Docker containers before your changes take effect.
Updating
To update Investbrain using the recommended Docker installation method, you just need to stop the running containers:
docker compose stop
Then pull the latest updates from this repository using git:
git pull
Then bring the containers back up!
docker compose up
Easy as that!
Command line utilities
Investbrain comes bundled with several helpful command line utilities to make managing your portfolios and holdings more efficient. Keep in mind these commands are extremely powerful and can make irreversable changes to your holdings.
To run these commands, you can use docker exec like this:
docker exec -it investbrain-app php artisan <replace with command you want to run>
Just to be safe, we recommend backing up your portfolios before using these commands:
| Command | Description |
|---|---|
| refresh:market-data | Refreshes market data with your configured market data provider. |
| refresh:dividend-data | Refreshes dividend data with your configured market data provider. Will also re-calculate your total dividends earned for each holding. |
| refresh:split-data | Refreshes splits data with your configured market data provider. Will also create new transactions to account for any splits. |
| capture:daily-change | Captures a snapshot of each portfolio's daily performance. |
| sync:daily-change | Re-calculates daily snapshots of your portfolio's daily performance. Useful to fill in gaps in your portfolio charts. (Note: this is an extremely resource intensive query.) |
| sync:holdings | Re-calculates performance of holdings with related transactions (i.e. dividends, realized gains, etc). |
Testing
Investbrain has a complete PHPUnit test suite that creates an in-memory SQLite database and runs any queued jobs synchronously using Laravel's array driver. You can run the entire Investbrain test suite from within the Docker container by running:
docker exec -it investbrain-app php artisan test
