cashier-ledger-server-go

A simple Rest API server for ledger-cli. Used by Cashier PWA.

Purpose

This is an server application that provides a Rest API endpoint. All it does is forward the received ledger-cli command to the ledger executable and sends back the result. It is a simple proxy for HTTP(S) requests and an instance of ledger-cli.

It effectively replaces CashierSync and CashierSync Go. By simplifying the server-side componenent, all the logic is able to reside in Cashier. Any future feature additions will not require changes in the server-side component.

Ledger-cli must be in the path, executable from the current location. It is advised to have a .ledgerrc file in the current directory, to set up the Ledger data sources.

For additional information, see related projects.

Development

The app is developed in Go(lang).

To debug, simply Run & Debug from vscode. Or create a new configuration to attach to process "fresh".

Hot Reload

To use hot reload during development, simply install Fresh package

go get github.com/pilu/fresh
go install github.com/pilu/fresh

and then run fresh from the project root directory. It will monitor source code files for changes and automatically rebuild the application.

Option B: Use Gin package? Doesn't work.

gin

Manual Tests

The API endpoints are listed in the ledger-server.rest file.

Installation

go install github.com/MisterY/cashier-ledger-server-go@latest

Remove

The app gets installed into $GOPATH/bin. To remove, simple delete the executable file.

Run

cashier-ledger-server-go [-p <port>]

The port parameter is optional. By default, the API will serve at port 8080.

Query

The server supports CORS and can be queried from a PWA JavaScript application.

Simply issue a GET request to the //server?command=... For example, when running on localhost, the URL would be http://localhost:8080?command=bal assets and cash.

where command is the ledger-cli command, just the parameters. i.e. balance assets Parameters are also supported, so something like bal -b 2022-08-10 is possible.

The result, ledger-cli output, is split into lines and return as a JSON array, which can be previewed in a browser or parsed by client apps/tools.
