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.

Sponsor our contributors on Open Collective, Logseq will move to Stripe later!

Why Logseq?

Logseq is a platform for knowledge management and collaboration. It focuses on privacy, longevity, and user control.

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.

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
• sci - Small Clojure Interpreter

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

We also have a dedicated page for LogSeq's codebase overview.

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
cd 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 Cypress tests

yarn e2e-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

MacOS/Linux

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

Windows

docker run -v %cd%:/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

Thanks
