CLI tool to redact/anonymize PostgreSQL dump generated via pg_dump with COPY statement

anon -i ./input.dump -o ./output.dump -t ./example-transformers.js

The transformer file is a file where you describe how and what you want to redact.

It's a Javascript file with that export an object.

Each root keys of this object represent the table name where you want to alter data.

Nested keys are the column name that you want to match, the value is a function that will be called when matching. The value of the column is passed as argument of this function.

const Chance = require("chance");
const chance = new Chance();

module.exports = {
  user: {
    email: () => chance.email()
  }
};

With this transformer, only values of the column email of the table user will be replace by a random value provided by the Chance package.
