Logseq

A local-first, non-linear, outliner notebook for organizing and sharing your personal knowledge base.

Use it to organize your todo list, to write your journals, or to record your unique life.

Why Logseq?

Logseq is a platform for knowledge sharing and management. It focuses on privacy, longevity, and user control. Notice: the backend code will be open-sourced as soon as we’re sure that the backend service meets the security standards.

The server will never store or analyze your private notes. Your data are plain text files and we currently support both Markdown and Emacs Org mode (more to be added soon).

In the unlikely event that the website is down or cannot be maintained, your data is, and will always be yours.

How can I use it?

Make sure you have registered a GitHub account and already created a repository (could be an old one). Currently we only support GitHub, but more sync options (e.g. Gitlab, Dropbox, Google Drive, WebDAV, etc.) will be added soon.

Credits

Logseq is hugely inspired by Roam Research, Org Mode, Tiddlywiki, Workflowy and Cuekeeper, hats off to all of them!

Logseq is also made possible by the following projects:

Clojure & ClojureScript - A dynamic, functional, general-purpose programming language
DataScript - Immutable database and Datalog query-engine for Clojure, ClojureScript and JS
OCaml & Angstrom, for the document parser
isomorphic-git - A pure JavaScript implementation of Git for node and browsers

The following is for developers and designers who want to build and run Logseq locally and contribute to this project.

Set up development environment

1. Requirements

Node.js & Yarn
Java & Clojure. (If you run into Execution error (FileNotFoundException) at java.io.FileInputStream/open0 (FileInputStream.java:-2). -M:cljs (No such file or directory), it means you have a wrong Clojure version installed. Please uninstall it and follow the instructions linked.)

2. Compile to JavaScript

git clone https://github.com/logseq/logseq
yarn
yarn watch

3. Open the browser

Open http://localhost:3001.

4. Build a release

yarn release

5. Run tests

Run ClojureScript tests

yarn test

Run Clojure tests. (Note: .cljc files may be tested both by ClojureScript, and Clojure.)

clj -Mtest-clj

Desktop app development

1. Compile to JavaScript

yarn watch

2. Open the dev app

yarn dev-electron-app

3. Build a release

yarn release-electron

Alternative: Docker based development environment

Basically it just pre-installs Java, Clojure and NodeJS for your convenience.

1. Fetch sources

git clone https://github.com/logseq/logseq

2. Build Docker image

cd logseq
docker build -t logseq-docker .

3. Run Docker container

docker run -v $(pwd):/home/logseq/logseq -p 3001:3001 -p 9630:9630 -p 8701:8701 --rm -it logseq-docker /bin/bash

4. Inside the container compile as described above

cd logseq
yarn
yarn watch
