# pg-migration

## What is it?

NodeJS lacks support for good proper ORMs, and most ORMs tend to suck a bit in the end anyway.
For [inventid](https://www.inventid.nl) I therefore developed this simple nodejs version for postgresql of [Liquibase](http://www.liquibase.org/).
It is based on the excellent [node-postgres](https://github.com/brianc/node-postgres) library.

## The database changelog table

pg-migration will automatically create the table (`dbchangelog`) for you.

## How to use

1. Import the library `import migrateAndStart from 'pg-migration';`
1. Create a valid database client connection
1. Create the migration, with that client, and a callback to the server start (e.g. `migrateAndStart(db, './migrations', startServer);`)

Files called `README.md` and `dbchangelog.sql` from the migrations folder are ignored.

Since the changeset id is derived from the file name, you can use the following command to create a new one

```bash
touch `date +%Y%m%d%H%M%S`.sql
```

Please be careful that the files will be executed in a alphabetically sorted fashion, so ensure that files do not depend on anything later (it's really a poor mans Liquibase).

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.
