+# NodeInject
+An inject tools for injecting js code into electron application
+
+Please follow DMCA when using this code
+### How it works
+
+1. unpack `node_modules.asar` package (in `./resources`)
+2. write `hook.js`  into `raven` package directory (raven will be required at the early stage of startup in some application)
+3. modify `index.js` of `raven`,injecting require of `hook.js`
+
+> Currently using embedded javascript file (`hooklog.js`)
+
+### Usage
+
+1. modify `hook.js` if you need or enable `no_embed` feature to use specified js (`NO_EMBED_HOOK_JS_PATH`)  at runtime
+2. use `cargo build` to make  executable with embedded js or `cargo build --features no_embed` without embedded js
+3. Move the program to the electron application directory
+4. run
+
+
+### Compatibility test
+
+- Windows / Typora 1.4.8          PASSED
+- Ubuntu / Typora 1.4.7             PASSED
+
+Since macos may adopt different packaging methods and webkit as the execution environment, this tool does not support applications under macos.
+
+### Examples
