In season of covid-19, maybe it is time for some upgrade.

Packages

I have 4 libraries need upgrading:

• ng2-simple-api-lib
• ng2-simple-global-lib
• ng2-simple-mq-lib
• ng2-simple-timer-lib

Manual Task

After following Angular Upgrade Guide, there are 4 files need update manually:

• LICENSE : Update year to 2020
• README.md : Update change log and license year to 2020
• package.json : Update version to 9.1.0
• projects/<library>/package.json : Maybe I did something wrong, other than the version, I also have to manually update "@angular/common": "~9.1.0", "@angular/core": "~9.1.0", and "rxjs": "~6.5.5"

Script

Once I get the above figure out, I created a simple script to take care of the rest:

#!/bin/bash

NG_VER="9.1.0"

# Assume README.md, LICENSE, package.json, projects/<library>/package.json already updated
git commit -a -m $NG_VER

ng update @angular/core@8 @angular/cli@8
git commit -a -m $NG_VER
ng update @angular/core @angular/cli
git add .
git commit -a -m $NG_VER

ng build $1 --prod
cp README.md LICENSE dist/$1/
cd dist/$1
npm publish

cd ../..
git tag -a $NG_VER -m $NG_VER
git push
git push --tags

Conclusion

Except the first one took 30min to figure out everything needed. The remaining 3 took less then 5 minutes each. The migration to angular-cli during version 8 last year really pay off nicely.
