logseq/deps/db

Description

This library provides a minimal API for using a datascript or SQLite database from the Logseq app and the CLI. This library is compatible with ClojureScript and with nbb-logseq to respectively provide frontend and commandline functionality.

API

This library is under the parent namespace logseq.db. This library provides three main namespaces, logseq.db, logseq.db.rules and logseq.db.sqlite.db.

Usage

See the frontend for example usage.

Dev

This follows the practices that the Logseq frontend follows. Most of the same linters are used, with configurations that are specific to this library. See this library's CI file for linting examples.

Setup

To run linters and tests, you'll want to install yarn dependencies once:

yarn install

This step is not needed if you're just running the application.

Testing

Testing is done with nbb-logseq and nbb-test-runner. Some basic usage:

# Run all tests
$ yarn test
# List available options
$ yarn test -H
# Run tests with :focus metadata flag
$ yarn test -i focus

Datalog linting

Datalog rules for the client are linted through a script that also uses the datalog-parser. To run this linter:

bb lint:rules

Managing dependencies

The package.json dependencies are just for testing and should be updated if there is new behavior to test.

The deps.edn dependencies are used by both ClojureScript and nbb-logseq. Their versions should be backwards compatible with each other with priority given to the frontend. No new dependency should be introduced to this library without an understanding of the tradeoffs of adding this to nbb-logseq.
