List of useful things for Mac Development

ATOM

• Get is a bad spot and Atom doesn’t open?

atom --clear-window-state

GIF’s

Install gifify

gifify {PATH_TO_INPUT} -o {PATH_TO_OUTPUT}

GIT

• To completely remove a file from git commit history run these two commands

git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch path_to_file" HEAD
git push origin master -f

• To reset local branch to remote

git fetch origin
git -B {branch-name}
git reset --hard origin/{branch-name}

• Delete remote branch

git push origin --delete {branch_name}

• Create a local copy of remote branch

git checkout -b <my_new_branch> <remote>/<branch_name>

• Change remote origin

git remote set-url origin git://new.url.here

• Ignore changes locally, but keep file in git (good for secrets)

git update-index --skip-worktree src/config/SECRETS.js

• Replace remote master with a new master by renaming and force pushing

git branch -m master old-master
git branch -m seotweaks master
git push -f origin master

• Delete all branches except master

git branch | grep -v "master" | xargs git branch -D

iOS

xcodebuild --help

Does the above fail? Try this: xcode => preferences => locations => Command Line Tools and select your version

• To list the uuid of signing certs

security find-identity -v -p codesigning

• To view uuid’s of provisioning profiles

/{root}/Library/MobileDevice/Provisioning Profiles

then less {file} will give you enough info to determine the proper file

• Archive a X-Code build, replace workspace with -project {PROJECT_NAME}.xcodeproj if it’s not a workspace instance

• Archive path will be the output file location used for exporting an IPA

xcodebuild -workspace {PROJECT_NAME}.xcworkspace -scheme {PROJECT_NAME} -configuration Release -archivePath ${archivePath} archive -quiet -sdk iphoneos

• Export an IPA

xcodebuild -exportArchive -archivePath ${archivePath} -exportPath ${exportPath} -exportOptionsPlist ${exportOptionsPlistPath}

• Export options plist example

<plist version="1.0">
<dict>
  <key>compileBitcode</key>
  <false/>
  <key>method</key>
  <string>enterprise</string>
  <key>signingCertificate</key>
  <string>{UUID}</string>
  <key>provisioningProfiles</key>
  <dict>
    <key>{bundle_ID}</key>
    <string>{UUID}</string>
  </dict>
  <key>signingStyle</key>
  <string>manual</string>
  <key>stripSwiftSymbols</key>
  <true />
  <key>teamID</key>
  <string>{TEAM_ID}</string>
</dict>
</plist>

• Direct download link for exterprise apps

itms-services://?action=download-manifest&url={URL_TO_MANIFEST_PLIST.plist}

• Push Noticiations .p12 to .pem

openssl pkcs12 -in pushcert.p12 -out pushcert.pem -nodes -clcerts

React-Native

• Bundle JavaScript

./node_modules/.bin/react-native bundle --entry-file index.js --platform ios --dev false --bundle-output ios/{PROJECT_NAME}/main.jsbundle

• Build Android App

cd android && ./gradlew clean && ./gradlew assembleRelease && cd ../

Heroku

• Create/Download Postgres .dump file

heroku pg:backups:capture
heroku pg:backups:download

heroku rollback v{whatever version} -r {whatever you call your remote}

git remote -v   <= will list remotes

Postgres

• Copy a .dump to localhost

pg_restore --verbose --clean --no-acl --no-owner -h localhost -d {DATABSE_NAME} {PATH_TO_DUMP_FILE}

• Debug localhost connections

postgres -D /usr/local/var/postgres

• Reset locally

TO COMPLETELY RESET POSTGRESQL LOCALLY

Chrome

• Unregister service workers chrome://serviceworker-internals/

Redis

This is nice:

/*  Some Constants File */
export const REDIS_PORT_OR_URL = isDev
  ? Number.parseInt(process.env.REDIS_PORT, 10)
  : process.env.REDISCLOUD_URL;

/* Some other file */
import redis from "redis";

import { REDIS_PORT_OR_URL } from "../constants";

const client = redis.createClient(REDIS_PORT_OR_URL, { no_ready_check: true });

export default client;

• start:redis start local server with chrome GUI

"start:redis": "concurrently --kill-others-on-fail \"yarn start:redis:server\" \"yarn start:redis:commander\" \"wait-on http://localhost:5002 && yarn open:chrome:redis:commander\""

"start:redis:server": "redis-server"

"start:redis:commander": "./node_modules/.bin/redis-commander -p 5002 "

"open:chrome:redis:commander": "open http://localhost:5002/"

NPM

• List config:

npm config list

• Set config:

npm set {key} {value}

.npmrc in root overrides local settings

• Private package settings

always-auth = true /* usually false */
metrics-registry = https://registry.npmjs.org/
registry = https://registry.npmjs.org/

MONGO

• Initial Installation

brew update
brew install mongodb
sudo mkdir -p /data/db
sudo chmod 0755 /data/db && sudo chown $USER /data/db

• Mongo Shell

mongo

* Within Mongo Shell
```bash
show dbs  // will list localhost dbs
```

• To Delete a localhost db, within Mongo Shell

  use <dbname from whatever show dbs lists>
  db.dropDatabase()
  

  
  
  

• Copy a remote Mongo from the database URI with the below format

mongodb://<username>:<password>@<url>:<port>/<database>

mongodump -h <url>:<port> -d <database> -u <username> -p <password>

mongodump will create a folder, within the current directory, dump/<database>/

• Copy a dump directory to localhost Mongo

mongorestore -d <dbname, same as the one dropped> <path to dump database dump/<database>/>

MYSQL

• start mysql.server start
• stop mysql.server stop
• Enter the mysql -u root shell after starting the mysql server
  • create database create database {name}; <– semi-colon IMPORTANT
  • exit exit;

mysql -u root -p
mysql> SET GLOBAL innodb_fast_shutdown = 1;
mysql> use mysql;
mysql> update user set plugin='mysql_native_password' where user='root';
mysql_upgrade -u root -p

• Client does not support authentication protocol requested by server on Sequelize migration???

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'

• MySQL all fucked up? Try this:

  mysqld stop
  

  
  
  

• Then this:

  brew update
  brew remove mysql
  brew install mysql
  

Rando

• Lists some good ip stuff

ifconfig

To stgream and save so to a file run

yarn start | tee filename.log

To debug dns and not found errors

8.8.8.8 is google’s dns and it should give you the ip of the end server

nslookup domain 8.8.8.8
