-
Make sure Java 7 is installed
-
Install Typesafe Activator version 1.2.x and ensure the
activator
binary is in$PATH
-
Run the server
$ activator run
[...]
--- (Running the application from SBT, auto-reloading is enabled) ---
[info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000
(Server started, use Ctrl+D to stop and go back to the console...)
- Install node.js and npm.
cd javascript/
npm install
npm run watch
or
npm run hot
for hot reloading.
The npm run watch
command will run the webpack --watch
task, which is continuously bundling JS whenever a source
file changes.
The npm run hot
command will run the webpack-dev-server
instead, which allows in-browser hot reloading.
In order to make switching between different branches faster, we use a script to store all node_modules
folders
into .node_cache
and then symlink the folder for the current branch to node_modules
.
When using IntelliJ or WebStorm, be sure to enable JSX harmony
(available in IntelliJ 14 and WebStorm 9)
as JavaScript language version to properly support react templates.
You might get an error message during npm install
from gyp
because the installed (default) Python version is too recent (sic!):
gyp ERR! stack Error: Python executable "python" is v3.4.2, which is not supported by gyp.
In this case just set the correct (installed!) Python binary before running npm install
:
npm config set python python2.7
a. Update a single dependency
- Update
package.json
file with the new dependency npm update <npm-package>
npm shrinkwrap --dev
to save the whole dependency tree into thenpm-shrinkwrap.json
file
b. Update devDependencies
npm shinkwrap
to keep the dependency tree (without devDependencies) intonpm-shrinkwrap.json
- Update
package.json
file with the new devDependencies npm install
- Do more work with the new devDependencies
npm shrinkwrap --dev
to export the whole dependency tree with the new devDependencies intonpm-shrinkwrap.json
