+# Magic bytes
+
+[![Build and test](https://github.com/LarsKoelpin/magic-bytes/actions/workflows/build-and-test.yml/badge.svg)](https://github.com/LarsKoelpin/magic-bytes/actions/workflows/build-and-test.yml)
+
+Magic Bytes is a javascript library analyzing the first bytes of a file to tell you its type. 
+Use it inside your browser or serversided using nodejs.
+
+The procedure is based on https://en.wikipedia.org/wiki/List_of_file_signatures.
+
+
+> [!NOTE]  
+> A small note on versioning.
+> Strictly speaking, each new filetype which is supported by this library can break someones' API.
+> Please note that this library adds new filetypes with minor release.
+> This means files, which validate to "null" in some versions, may find a result in a new version.
+> 
+> Or in some cases the library will find more results, than before. So don't depend on the found-array size in
+> any shape or form.
+> Filetypes will not be remoevd tho
+
+# Installation
+Run `npm install magic-bytes.js`
+
+
+# Interactive example
+There is an interactive example present at https://larskoelpin.github.io/magic-bytes/.
+
+# Usage
+
+The following functions are available:
+* `filetypeinfo(bytes: number[])` Contains typeinformation like name, extension and mime type: `[{typename: "zip"}, {typename: "jar"}]`
+* `filetypename(bytes: number[])` : Contains type names only: `["zip", "jar"]`
+* `filetypemime(bytes: number[])` : Contains type mime types only: `["application/zip", "application/jar"]`
+* `filetypeextension(bytes: number[])` : Contains type extensions only: `["zip", "jar"]`
+
+Both function return an empty array `[]` otherwise, which means it could not detect the file signature. Keep in mind that
+txt files for example fall in this category.
+
+You don't have to load the whole file in memory. For validating a file uploaded to S3 using Lambda for example, it may be  
+enough to load the files first 100 bytes and validate against them.  This is especially useful for big files.
+
+see examples for practical usage.
+
+On server:
+```javascript
+import filetype from 'magic-bytes.js'
+
+filetype(fs.readFileSync("myimage.png")) // ["png"]
+```
+
+
+To run an HTML-Example checkout the project and run
+
+```
+npm install; npm run example
+```
+
+This opens an HTML example using magic bytes as a window variable. It kinda looks like that.
+
+```html
+<input type="file" id="file" />
+
+ <script src="node_modules/magic-bytes.js/dist/browser.js" type="application/javascript"></script>
+<script>
+    document.getElementById("file").addEventListener('change', (event, x) => {
+      const fileReader = new FileReader();
+      fileReader.onloadend = (f) => {
+        const bytes = new Uint8Array(f.target.result);
+        console.log("Possible filetypes: " + filetypeinfo(bytes))
+      }
+      fileReader.readAsArrayBuffer(event.target.files[0])
+    })
+</script>
+```
+
+
+# Tests
+Run  `npm test`
+
+# Example
+See examples/
+
+# How does it work
+The `create-snapshot.js` creates a new tree. The tree has a similar shape to the following 
+```json
+{
+  "0x47": {
+    "0x49": {
+      "0x46": {
+        "0x38": {
+          "0x37": {
+            "0x61": {
+              "matches": [
+                {
+                  "typename": "gif",
+                  "mime": "image/gif",
+                  "extension": "gif"
+                }
+              ]
+            }
+          },
+        }
+      }
+    }
+  }
+}
+```
+
+It acts as a giant lookup map for the given byte signatures.
