Tons of Solutions Engineering work done today for the rest of the CS team! Headway, Howard Hanna, Engels, Brighton, etc. Also completed Datasnippers auth flow and worked on Anthology's script. Cloned Anthology's courses (900..) and will clone Full Story on Monday.

+# extract-zip
+
+Unzip written in pure JavaScript. Extracts a zip into a directory. Available as a library or a command line program.
+
+Uses the [`yauzl`](http://npmjs.org/yauzl) ZIP parser.
+
+[![NPM](https://nodei.co/npm/extract-zip.png?global=true)](https://npm.im/extract-zip)
+[![Uses JS Standard Style](https://cdn.jsdelivr.net/gh/standard/standard/badge.svg)](https://github.com/standard/standard)
+[![Build Status](https://github.com/maxogden/extract-zip/workflows/CI/badge.svg)](https://github.com/maxogden/extract-zip/actions?query=workflow%3ACI)
+
+## Installation
+
+Make sure you have Node 10 or greater installed.
+
+Get the library:
+
+```
+npm install extract-zip --save
+```
+
+Install the command line program:
+
+```
+npm install extract-zip -g
+```
+
+## JS API
+
+```javascript
+const extract = require('extract-zip')
+
+async function main () {
+  try {
+    await extract(source, { dir: target })
+    console.log('Extraction complete')
+  } catch (err) {
+    // handle any errors
+  }
+}
+```
+
+### Options
+
+- `dir` (required) - the path to the directory where the extracted files are written
+- `defaultDirMode` - integer - Directory Mode (permissions), defaults to `0o755`
+- `defaultFileMode` - integer - File Mode (permissions), defaults to `0o644`
+- `onEntry` - function - if present, will be called with `(entry, zipfile)`, entry is every entry from the zip file forwarded from the `entry` event from yauzl. `zipfile` is the `yauzl` instance
+
+Default modes are only used if no permissions are set in the zip file.
+
+## CLI Usage
+
+```
+extract-zip foo.zip <targetDirectory>
+```
+
+If not specified, `targetDirectory` will default to `process.cwd()`.
