+# pgpass
+
+[![Build Status](https://github.com/hoegaarden/pgpass/workflows/CI/badge.svg?branch=master)](https://github.com/hoegaarden/pgpass/actions?query=workflow%3ACI+branch%3Amaster)
+
+## Install
+
+```sh
+npm install pgpass
+```
+
+## Usage
+```js
+var pgPass = require('pgpass');
+
+var connInfo = {
+  'host' : 'pgserver' ,
+  'user' : 'the_user_name' ,
+};
+
+pgPass(connInfo, function(pass){
+  conn_info.password = pass;
+  // connect to postgresql server
+});
+```
+
+## Description
+
+This module tries to read the `~/.pgpass` file (or the equivalent for windows systems). If the environment variable `PGPASSFILE` is set, this file is used instead. If everything goes right, the password from said file is passed to the callback; if the password cannot be read `undefined` is passed to the callback.
+
+Cases where `undefined` is returned:
+
+- the environment variable `PGPASSWORD` is set
+- the file cannot be read (wrong permissions, no such file, ...)
+- for non windows systems: the file is write-/readable by the group or by other users
+- there is no matching line for the given connection info
+
+There should be no need to use this module directly; it is already included in `node-postgres`.
+
+## Configuration
+
+The module reads the environment variable `PGPASS_NO_DEESCAPE` to decide if the the read tokens from the password file should be de-escaped or not. Default is to do de-escaping. For further information on this see [this commit](https://github.com/postgres/postgres/commit/8d15e3ec4fcb735875a8a70a09ec0c62153c3329).
+
+
+## Tests
+
+There are tests in `./test/`; including linting and coverage testing. Running `npm test` runs:
+
+- `jshint`
+- `mocha` tests
+- `jscoverage` and `mocha -R html-cov`
+
+You can see the coverage report in `coverage.html`.
+
+
+## Development, Patches, Bugs, ...
+
+If you find Bugs or have improvements, please feel free to open a issue on GitHub. If you provide a pull request, I'm more than happy to merge them, just make sure to add tests for your changes.
