In #33823, `scripts/package-builds.sh` (which is used by both `build-packages-dist.sh` and `build-ivy-npm-packages.sh`) was updated to use `realpath`. It turns out that `realpath` does not exist on macOS, so the build scripts do not work there. In order to fix this (and also reduce the likelihood of introducing similar issues in the future), this commit changes these bash scripts to Node.js scripts (using [ShellJS](https://github.com/shelljs/shelljs) for a cross-platform implementation of Unix shell commands where necessary). PR Close #33854
Encryption
Based on https://github.com/circleci/encrypted-files
In the CircleCI web UI, we have a secret variable called KEY
https://circleci.com/gh/angular/angular/edit#env-vars
which is only exposed to non-fork builds
(see "Pass secrets to builds from forked pull requests" under
https://circleci.com/gh/angular/angular/edit#advanced-settings)
We use this as a symmetric AES encryption key to encrypt tokens like a GitHub token that enables publishing snapshots.
To create the github_token file, we take this approach:
- Find the angular-builds:token in http://valentine
- Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime:
docker run --rm -it circleci/node:10.12 - echo "https://[token]:@github.com" > credentials
- openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
- If needed, base64-encode the result so you can copy-paste it out of docker:
base64 github_token
