* Logseq
Logseq is a local-first, non-linear, outliner notebook for organizing and sharing your personal knowledge base.
** Website
https://logseq.com
** Setup development environment
If you're on Windows, use the [[#windows-setup][Windows setup]].
*** 1. Requirements
**** [[https://clojure.org/guides/getting_started][Java && Clojure]]
**** [[https://www.postgresql.org/download/][PostgreSQL]]
**** [[https://nodejs.org/en/][Node.js]]
*** 2. Add environment variables
#+BEGIN_SRC sh
export ENVIRONMENT="dev"
export GITHUB_APP_KEY="ecaceddfdb7158c4e384"
export GITHUB_APP_SECRET="3e337d07f61585576362c95dcb8cd98756e43f65"
export GITHUB_REDIRECT_URI="http://localhost:3000/auth/github"

export COOKIE_SECRET="10a42ca724e34f4db6086a772d787034"
export DATABASE_URL="postgres://localhost:5432/logseq"

export GITHUB_APP2_SECRET="3b952aa1c2f821a957ea1296039df6527fda5b6e"
# Replace your-code-directory with yours
export GITHUB_APP_PEM="/your-code-directory/logseq/pem/logseq-test.2020-08-27.private-key.pem"
#+END_SRC
*** 3. Start the clojure server
**** Using in Emacs
#+BEGIN_EXAMPLE
1. C-c M-j and select "clojure-cli"
2. input "(go)" in the clojure repl
#+END_EXAMPLE
**** Using in Cli
#+BEGIN_EXAMPLE
1. clj -A:dev
2. input "(go)" in the clojure repl
#+END_EXAMPLE
**** Using in Calva (Visual Studio Code)
#+BEGIN_EXAMPLE
1. Issue the command Start a REPL server and Connect: ctrl+alt+c ctrl+alt+j
2. Select clojure-cli
3. input "(go)" in the clojure repl
#+END_EXAMPLE
*** 4. Compile javascript
#+BEGIN_SRC sh
cd web
yarn
yarn watch
open http://localhost:3000
#+END_SRC
** Windows setup
*** 1. Required software
Install clojure through scoop-clojure: https://github.com/littleli/scoop-clojure. You can also install [[https://nodejs.org/en/][Node.js]], [[https://yarnpkg.com/][Yarn]] and [[https://www.postgresql.org/download/][PostgreSQL]] through scoop if you want to.
*** 2. Setup PostgreSQL
Make sure you have PostgreSQL running. You can check if it's running with ~pg_ctl status~ and use ~pg_ctl start~ to start it up.
You'll also need to make a logseq DB in PostgreSQL. Do that with ~createdb logseq~.
*** 3. Setup the server
Download [[https://gist.github.com/samfundev/98088dd76f67085f114c75493261aa3d][this little script]] that sets up the environment variables and runs ~cmd-clj -A:dev~.
The ~GITHUB_APP_PEM~ variable in the script needs to be set with the correct directory for your system.
Run that script in the repo and enter ~(go)~ into the interpreter.
*** 4. Setup the website
Either run ~cmd-clojure -A:cljs watch app~ instead of ~yarn watch~ in the next step or modify web/package.json to use cmd-clojure instead of clojure in the scripts section.
Open command prompt in the repo and do:
#+BEGIN_SRC batch
cd web
yarn
yarn watch
#+END_SRC
Wait for it to compile and open ~localhost:3000~.
*** Notes
1. The clojure deps should be synced between the two files: ~project.clj~ and ~deps.edn~.
We need the ~project.clj~ because it's used for dokku deployment.
2. To use github push, comment this line https://github.com/tiensonqin/logseq/blob/master/web/src/main/frontend/handler.cljs#L751
