## About
[DcaPal](https://dcapal.com) is a pragmatic **Dollar Cost Averaging tool** for passive investors like me:
financially-educated people managing their own portfolios of not-too-many assets replicating major world indices.
I was facing a common problem: it's that time of the month, got some savings to invest and have to split them across my
portfolio assets. *How the heck can I do it so that my portfolio stays balanced?*
Hence DcaPal. You come here every week/month/quarter, build your portfolio, define asset allocation in percentage, input
how much you want to invest and **let the algorithm do the splitting for you**.
## Demo

## Getting started
You can start using [DcaPal](https://dcapal.com) right away. It's free. No registration required.
**Build** your own portfolio or, if you don't know where to start, explore our **Demo** portfolios:
- [60/40 Portfolio](https://dcapal.com/demo/60-40)
- [All-seasons Portfolio](https://dcapal.com/demo/all-seasons)

## Build Instructions
DcaPal does not store any user data. But if you are still concerned for your privacy, you can build and run it on your
machine.
**Start Docker environment**
- Setup the `.env` file
```bash
cp dcapal-backend/.env.example dcapal-backend/.env
```
- Setup a password for the db and the JWT secret (you can use `openssl rand -base64 32` to generate a random string) in
the new `.env` file
```dotenv
POSTGRES_PASSWORD=
JWT_SECRET=
```
- Start the Docker environment
```bash
make dev-up
```
(Note: if you're using a Mac with an ARM processor, you should replace (in the docker-compose dev file) Cadvisor's image
version with gcr.io/cadvisor/cadvisor:v0.47.1 and set platform: linux/aarch64)
**Run DcaPal backend**
Prepare `dcapal.yml` config file
```bash
cd dcapal-backend
cp config/dcapal/dcapal.yml dcapal.yml
```
Compile and start backend service
```bash
cargo run --release
```
**Run DcaPal frontend**
Build DcaPal Optimizer
```bash
cd dcapal-optimizer-wasm
curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
wasm-pack build --release
```
Install NPM dependencies. Note: this is installing `dcapal-optimizer-wasm` package as well.
```bash
cd ../dcapal-frontend
npm install # Install dcapal-optimizer-wasm pkg as well
```
Run frontend server
```bash
npm run start
```
