-
-### Motivation
+## Motivation and Features
 
+- Self contained applications
 - Ability to run multiple applications with *different* node.js runtimes.
-- Distributable binaries without needing node / npm.
-- Starts faster.
+- Distribute binaries without needing node / npm.
+- Idempotent builds
+- Start and deploy faster.
 - Lockdown specific application versions, and easily rollback.
-- Faster deployments.
+- Flexible build pipeline
+- Cross platform builds
 
-## Building Requirements
+## Usage
 
-- Linux / Mac / BSD / Windows
-- Python 2.6 or 2.7 (use --python if not in PATH)
-- Windows: Visual Studio 2010+
+- Application entrypoint:
 
-## Caveats
+  `nexe my-app.js`
 
-### Doesn't support native modules
+- stdin interface
 
-- Use the techniques below for working around dynamic require statements to exclude the module from the bundling, and deploy along side the executable in a node_module folder so your app can find it. Note: On windows you may need to have your app be named node.exe if .node file depends on node.
+  `rollup -c | nexe --resource "./public/**/*" -o my-app.exe`
 
-### Doesn't support dynamic require statements
+For more CLI options see: `nexe --help`
 
-Such As:
+### Examples
+
+- `nexe server.js -r "public/**/*.html"`
+- `nexe --build`
+- `nexe -t x86-8.0.0`
+
+## Resources
+
+Additional files or resources can be added to the binary by passing `-r "glob/pattern/**/*"`. These included files can be read in the application by using `fs.readFile` or `fs.readFileSync`.
+
+## Compiling Node
+
+By default `nexe` will attempt to download a pre-built executable. However, It may be unavailable ([github releases](https://github.com/nexe/nexe/releases))
+or you may want to customize what is built. See `nexe --help` for a list of options available when passing the [`--build`](#build-boolean) option. You will also need to ensure your environment is setup to [build node](https://github.com/nodejs/node/blob/master/BUILDING.md). Note: the `python` binary in your path should be an acceptable version of python 2. eg. Systems that have python2 will need to create a [symlink](https://github.com/nexe/nexe/issues/354#issuecomment-319874486).
+
+## Node.js API
+
+#### Example
 
 ```javascript
-var x = require(someVar);
+const { compile } = require('nexe')
+
+compile({
+  input: './my-app.js',
+  build: true, //required to use patches
+  patches: [
+    async (compiler, next) => {
+      await compiler.setFileContentsAsync(
+        'lib/new-native-module.js',
+        'module.exports = 42'
+      )
+      return next()
+    }
+  ]
+}).then(() => {
+  console.log('success')
+})
+```
+## NexeOptions
+
+### `options: object`
+
+ - #### `input: string`
+    - Input bundle file path
+    - default: stdin or the current directory's main file (package.json)
+ - #### `output: string`
+    - Output executable file path
+    - default: same as `name` with an OS specific extension.
+ - #### `target: string | object`
+    - An object or string describing platform-arch-version. e.g. `'windows-ia32-10.13.0'`
+      - each segment is optional, and will be merged with the current environment
+      - Examples: ([full list](https://github.com/nexe/nexe/releases))
+        - `'win32-x86-10.13.0`
+        - `{ platform: 'alpine' }`
+        - `darwin-10.13.0`
+        - `linux-x64`
+        - `macos-10.13.0`
+
+        See [test/target.spec.ts](test/target.spec.ts)
+    - If the [`build`](#build-boolean) flag is set, the platform portion of the target is ignored.
+    - default: `process`
+- #### `bundle: string | boolean`
+    - If a string is provided it must be a valid relative module path
+    and should provide an export with the following signature:
+    ```typescript
+    export function createBundle (options: NexeOptions): Promise<string>
+    ```
+    - default: true
+ - #### `name: string`
+    - Module friendly name of the application
+    - default: basename of the input file, or `nexe_${Date.now()}`
+ - #### `cwd: string`
+    - Directory nexe will operate on as though it is the cwd
+    - default: process.cwd()
+ - #### `mangle: boolean`
+    - If set to false, nexe will not include the virtual filesystem (your application and resources) on the output.
+    - This will cause the output to error as an "Invalid Binary" unless a userland patch alters the contents of lib/_third_party_main.js in the nodejs source.
+    - default: true
+ - #### `build: boolean`
+    - Build node from source, passing this flag tells nexe to download and build from source. Subsequently using this flag will cause nexe to use the previously built binary. To rebuild, first add [`--clean`](#clean-boolean)
+ - #### `asset: string`
+    - Provide a pre-built nexe binary asset, this can either be an http or https URL or a file path.
+    - default: `null`
+ - #### `python: string`
+    - On Linux this is the path pointing to your python2 executable
+    - On Windows this is the directory where `python` can be accessed
+    - default: `null`
+ - #### `flags: string[]`
+    - Array of node runtime flags to build node with.
+    - Example: `['--expose-gc']`
+    - default: `[]`
+ - #### `configure: string[]`
+    - Array of arguments for the node build configure step
+    - Example: `['--with-dtrace', '--dest-cpu=x64']`
+    - default: `[]`
+ - #### `make: string[]`
+    - Array of arguments for the node build make step
+    - default: `[]`
+ - #### `vcBuild: string[]`
+    - Options for windows build
+    - default: `['nosign', 'release']`
+ - #### `snapshot: string`
+    - path to a file to be used as the warmup snapshot for the build
+    - default: `null`
+ - #### `resources: string[]`
+    - Array of globs with files to include in the build
+    - Example: `['./public/**/*']`
+    - default: `[]`
+ - #### `temp: string`
+    - Path to use for storing nexe's build files
+    - Override in the env with `NEXE_TEMP`
+    - default: `~/.nexe`
+ - #### `ico: string`
+    - Path to a user provided icon to be used (Windows only). Requires `--build` to be set.
+ - #### `rc: object`
+    - Settings for patching the [node.rc](https://github.com/nodejs/node/blob/master/src/res/node.rc) configuration file (Windows only).
+    - Example (keys may vary depending ont the version. Reference the file linked above):
+      ```javascript
+        {
+          CompanyName: "ACME Corp",
+          PRODUCTVERSION: "17,3,0,0",
+          FILEVERSION: "1,2,3,4"
+          ...
+        }
+      ```
+    - default: `{}`
+ - #### `clean: boolean`
+    - If included, nexe will remove temporary files for the accompanying configuration and exit
+ - #### `enableNodeCli: boolean`
+    - Enable the original Node CLI (will prevent application cli from working).
+    - Node CLI arguments passed via the [NODE_OPTIONS](https://nodejs.org/api/cli.html#cli_node_options_options) environment
+      variable will still be processed. NODE_OPTIONS support can be disabled with the `--without-node-options` configure flag.
+    - default: `false`
+  - #### `fakeArgv: boolean`
+    - fake the entry point file name (`process.argv[1]`). If nexe was used with stdin this will be `'[stdin]'`.
+ - #### `ghToken: string`
+    - Provide a Github Token for accessing nexe releases
+    - This is usually needed in CI environments
+    - default: `process.env.GITHUB_TOKEN`
+ - #### `sourceUrl: string`
+    - Provide an alternate url for the node source code
+    - Note: temporary files will still be created for this under the specified version
+ - #### `loglevel: string`
+    - Set the loglevel, info, silent, or verbose
+    - default: `'info'`
+ - #### `patches: NexePatch[]`
+    - Userland patches for patching or modifying node source
+    - default: `[]`
+ - #### `plugins: NexePatch[]`
+    - Userland plugins for modifying nexe executable behavior
+    - default: `[]`
+
+### `NexePatch: (compiler: NexeCompiler, next: () => Promise<void>) => Promise<void>`
+
+Patches and Plugins are just a middleware functions that take two arguments, the `compiler`, and `next`. The compiler is described below, and `next` ensures that the pipeline continues. Its invocation should always be awaited or returned to ensure correct behavior. Patches also require that [`--build`](#build-boolean) be set, while plugins do not.
+
+For examples, see the built in patches: [src/patches](src/patches).
+
+### `NexeCompiler`
+
+ - `setFileContentsAsync(filename: string, contents: string): Promise<void>`
+    - Quickly set a file's contents within the downloaded Node.js source.
+ - `replaceInFileAsync(filename: string, ...replaceArgs): Promise<void>`
+    - Quickly perform a replace in a file within the downloaded Node.js source. The rest arguments are passed along to `String.prototype.replace`
+ - `readFileAsync(filename: string): Promise<NexeFile>`
+    - Access (or create) a file within the downloaded Node.js source.
+ - `addResource(filename: string, contents: Buffer): void`
+    - Add a resource to the nexe bundle
+ - `files: NexeFile[]`
+    - The cache of the currently read, modified, or created files within the downloaded Node.js source.
+
+#### `NexeFile`
+  - `contents: string`
+  - `absPath: string`
+  - `filename: string`
+
+Any modifications made to `NexeFile#contents` will be maintained in the cache _without_ the need to explicitly write them back out, e.g. using `NexeCompiler#setFileContentsAsync`.
+
+## Native Modules
+
+TODO
+
+- [ ] Implement support for `node-pre-gyp#find`.
+
+## Contributing
+
+Building
+```
+$ git clone git@github.com:nexe/nexe.git
+$ cd nexe
+$ yarn
 ```
 
-In this case nexe won't bundle the file
-
-```javascript
-	var x;
-	if (someCheck) {
-		x = require("./ver1.js");
-	} else {
-		x = require("./ver2.js");
-	}
+Testing
 ```
-
-In this case nexe will bundle both files.
-
-Workarounds:
-1) for dynamic requires that you want bundled add the following into your project
-
-```javascript
-	var dummyToForceIncludeForBundle = false;
-	if (dummyToForceIncludeForBundle) {
-		require("./loadedDynamicallyLater.js");
-		// ...
-	}
+$ npm test
 ```
-this will trick the bundler into including them.
-
-2) for dynamic files getting included that you don't want to be
-
-```javascript
-	var moduleName = "./ver2.js";
-	if (someCheck) {
-		moduleName = "./ver1.js";
-	}
-	var x = require(moduleName);
-```
-Note: neither file will be bundled.
-
-Using these two techniques you can change your application code so modules are not bundles, and generate a includes.js file as part of your build process so that the right files get bundled for your build configuration.
-
-### &#95;&#95;dirname
-
-Once the module is bundled it is part of the executable. &#95;&#95;dirname is therefore the executable dir (process.execPath). Thus if you put resources on a relative path from the the executable your app will be able to access them.
-
-If you had a data file at `/dev/myNodeApp/stateManager/handler/data/some.csv`
-and a file at `/dev/myNodeApp/stateManager/handler/loader.js`
-
-```javascript
-	module.exports = fw.readFileSync(path.join(__dirname, "./data/some.csv"));
-```
-You would need to deploy some.csv in a sub dir `data/` along side your executable
-
-There are potential use cases for &#95;&#95;dirname where the executable path is not the correct substitution, and could result in a silent error (possibly even in a dependency that you are unaware of).
-
-Note: &#95;&#95;filename will be 'undefined'
-
-### child_process.fork
-
-child_process.spawn works is unmodified, but child_process.fork will make an attempt to launch a new instance of your executable and run the bundled module.
-

-
-### package.json inclusion
-
-As of 0.4.0 you can now embed nexe options into package.json. Note that this Format
-is still in works, so it is likely to change.
-
-```json
-"nexe": {
-	"input": "./bin/nexe",
-	"output": "nexe^$",
-	"temp": "src",
-	"browserify": {
-		"requires": [],
-		"excludes": [],
-		"paths": []
-	},
-	"runtime": {
-		"framework": "node",
-		"version": "5.6.0",
-		"js-flags": "--use_strict",
-		"ignoreFlags": true
-	}
-}
-```
-
-Notes:
-
-* output: can use ^$ for platform specific file extension
-* js-flags: this is also known as v8 flags, and supports *all* v8 flags.
-
-### Browserify Require Issues
-
-If you have requires that aren't resolving well, you can do two things.
-
-Try adding it to `nexe.browserify.requires` in your `package.json`
-
-```json
-"nexe": {
-	.......
-	"browserify": {
-		"requires": [
-			{
-				"file": "myfile.js",
-				"expose": "mymodule"
-			},
-			"mymodule.js"
-		],
-		"excludes": [],
-		"paths": []
-	},
-	.......
-}
-```
-
-Or, if that doesn't work (it tends to not work sometimes), you can try altering
-browserify.paths like so:
-
-```json
-"nexe": {
-	.......
-	"browserify": {
-		"requires": []
-		"excludes": [],
-		"paths": ["/path/to/my/loc"]
-	},
-	.......
-}
-```
-
-If it *still* doesn't work, file a bug with what you tried! (also try using `nexe@0.4.2`)

+# nexe-fs
+
+### Getting Started:
+
+This module contains a set of patches used to create (and use) the Nexe Virtual FileSystem
+
+In order for NVFS to work with node's `require` method. A custom build of node must be used. If using the `nexe` cli this will be handled automatically
+
+The customization should be applied as early as possbile when node is starting up. 
+
+i.e. The contents of `nexe-fs/bootstrap` should be put [here](https://github.com/nodejs/node/blob/0827c80920311fa9d1e6989c8a73aaaeca962eb7/lib/internal/bootstrap/node.js#L27-L28).
+
+### Creating a NVFS:
+
+To create a virtual file system use the `Bundle` Object, in your build process:
+
+```javascript
+const { Bundle } = require('nexe-fs')
+
+const bundle = new Bundle()
+await bundle.addResource(absoluteFileName)
+
+bundle.toStream().pipe(fs.createWriteStream('./myFsBlob'))
+```
+
+In the entrypoint of your application, the fs patch needs to be applied (executed as early as possible)
+For example, In the build process, the application's entrypoint could be prepended with the following:
+
+```javascript
+const codeToPrependToEntrypoint = fs.readFileSync(require.resolve('nexe-fs/patch'), 'utf-8') + `
+shimFs({
+  blobPath: 'location/of/myFsBlob',
+  resources: ${JSON.stringify(bundle)},
+  layout: {
+    resourceStart: 0 // the offset within the blob that is referenced by the bundle index
+  }
+})`
+```
+
+Since a custom node build is being used. A great place for this code would be the node source file: `_third_party_main.js`
