Too Many Metafiles and chest.js @watilde
@author • @watilde • npm publish / month • beeplay,
tvm, jsss • Bootstrap / Ratchet / Flight / Node <3
• PHP @work
Main Subject "Too many metafiles"
Front End Development Tools
tool name file name npm • package.json • .npmrc •
node_modules jshint • .jshintrc • .jshintignore Grunt • Gruntfile.js gulp • gulpfile.js editorconfig • .editorconfig bower • bower.json • .bowerrc component.io • component.json etc… have some metafiles:
Tripling Each Year 0 1 2 3 5 6 7
8 9 2012 2013 2014 Number of metafiles I use frequently
Next Year: 27 Files!? 0 5 10 15 20 25
30 2012 2013 2014 2015 Number of metafiles I use frequently Just kidding XD (maybe…)
4 Problems • Ugly root directory • Init process growing
increasingly complex • Need a "Package Manager" manager • Too many different types of commands
• Ugly root directory • Init process growing increasingly complex
• Need a "Package Manager" manager • Too many different types of commands 4 Problems These are resolved by the current version of chest.js
Ugly root directory •Routine example: $ cd ~/project/ $ ls
.editorconfig .git/ .gitignore .travis.yml .jshintrc bower.json CONTRIBUTING.md Gruntfile.js README.md bin/ lib/ package.json power_assert.js spec/ src/
Init process growing increasingly complex • Most users of these
front end development tools are web designers • Many of them don’t like terminal • Have to run many commands;(
Symbolic Link + .gitignore $ ls ./.meta - package.json -
bower.json ! $ ln -s .meta/* ./ ! $ cat .gitignore ./package.json ./bower.json
npm run-scripts // package.json "scripts": { "install": "ln -s .meta/*
./", "postinstall": "bower install" }, https://www.npmjs.org/doc/scripts.html
Easier
http://chestjs.com/ Enter chest.js
Getting started
e.g) General example project: $ cd ~/project/ $ ls .editorconfig
.git/ .gitignore .travis.yml .jshintrc bower.json CONTRIBUTING.md Gruntfile.js README.md bin/ lib/ package.json power_assert.js spec/ src/
Install chest command $ npm install -g chest $ chest
! @see ‘chest usage’
Put metafiles in the chest $ chest put .editorconfig .travis.yml
Gruntfile.js package.json power_assert.js ! $ ls .chest .git/ .gitignore CONTRIBUTING.md README.md bin/ lib/ spec/ src/
Show list $ chest list .editorconfig .travis.yml bower.json Gruntfile.js package.json
power_assert.js
Create symbolic link $ chest open $ ls .editorconfig .git/
.gitignore .travis.yml .jshintrc bower.json CONTRIBUTING.md Gruntfile.js README.md bin/ lib/ package.json power_assert.js spec/ src/
Support install $ chest install ! run npm install run
bower install
Open & Install in postinstall $ cat package.json ɾɾɾ "scripts":
{ "postinstall": "chest boost" }, ɾɾɾ
What’s next?
• Ugly root directory • Init process growing increasingly complex
• Need a "Package Manager" manager • Too many different types of commands 4 Problems Will resolve these in future versions of chest.js
Need a "Package Manager" manager •Version, Name, Description, etc •Currently
when updating one metafile, you have to changes all the others manually •Ideally, chest.js will manage this info with one base file
Too many different types of commands •case(grunt || gulp) write
usage •Others: npm-run-script, make, bash, etc •difficult to write usage •Challenging to ensure backward compatibility for commands
chest.json { name: ‘node-gakuen’, description: ‘A school for node lovers’,
version: ‘4.13.6’, scripts: { build: { usage: ‘build all file’, run: ‘grunt build’ } } }
chest.json • chest syncɿsync both metainfo { name: ‘node-gakuen’, description:
‘A school for node lovers’, version: ‘0.0.1’, scripts: { build: { usage: ‘build all files’, run: ‘grunt build’ } } }
chest.json •chest-run-scriptsɿcommand rapper required usage { name: ‘node-gakuen’, description: ‘A
school for node lovers’, version: ‘0.0.1’, scripts: { build: { usage: ‘build all file’, run: ‘grunt build’ } } }
