+# Builders Developer Reference
+
+The following page is a reference for how to create a Builder using the available Builder's API.
+
+A Builder is an npm module that exposes a `build` function and optionally an `analyze` function and `prepareCache` function.
+Official Builders are published to [npmjs.com](https://npmjs.com) as a package and referenced in the `use` property of the `now.json` configuration file.
+However, the `use` property will work with any [npm install argument](https://docs.npmjs.com/cli/install) such as a git repo url which is useful for testing your Builder.
+
+See the [Builders Documentation](https://zeit.co/docs/v2/advanced/builders) to view example usage.
+
+## Builder Exports
+
+### `version`
+
+A **required** exported constant that decides which version of the Builder API to use.
+
+The latest and suggested version is `2`.
+
+### `analyze`
+
+An **optional** exported function that returns a unique fingerprint used for the purpose of [build de-duplication](https://zeit.co/docs/v2/advanced/concepts/immutability#deduplication-algorithm). If the `analyze` function is not supplied, a random fingerprint is assigned to each build.
+
+```js
+export analyze({
+  files: Files,
+  entrypoint: String,
+  workPath: String,
+  config: Object
+}) : String fingerprint
+```
+
+If you are using TypeScript, you should use the following types:
+
+```ts
+import { AnalyzeOptions } from '@now/build-utils'
+
+export analyze(options: AnalyzeOptions) {
+  return 'fingerprint goes here'
+}
+```
+
+### `build`
+
+A **required** exported function that returns a [Files](#files) data structure that contains the Build outputs, which can be a [Static File](#file) or a [Serverless Function](#serverless-function).
+
+What's a Serverless Function? Read about [Serverless Function concepts](https://zeit.co/docs/v2/deployments/concepts/lambdas) to learn more.
+
+```js
+build({
+  files: Files,
+  entrypoint: String,
+  workPath: String,
+  config: Object,
+  meta?: {
+    isDev?: Boolean,
+    requestPath?: String,
+    filesChanged?: Array<String>,
+    filesRemoved?: Array<String>
+  }
+}) : {
+  watch: Array<String>,
+  output: Files output,
+  routes: Object
+}
+```
+
+If you are using TypeScript, you should use the following types:
+
+```ts
+import { BuildOptions } from '@now/build-utils'
+
+export build(options: BuildOptions) {
+  // Build the code here
+
+  return {
+    output: {
+      'path-to-file': File,
+      'path-to-lambda': Lambda
+    },
+    watch: [],
+    routes: {}
+  }
+}
+```
+
+### `prepareCache`
+
+An **optional** exported function that is equivalent to [`build`](#build), but it executes the instructions necessary to prepare a cache for the next run.
+
+```js
+prepareCache({
+  files: Files,
+  entrypoint: String,
+  workPath: String,
+  cachePath: String,
+  config: Object
+}) : Files cacheOutput
+```
+
+If you are using TypeScript, you can import the types for each of these functions by using the following:
+
+```ts
+import { PrepareCacheOptions } from '@now/build-utils'
+
+export prepareCache(options: PrepareCacheOptions) {
+  return { 'path-to-file': File }
+}
+```
+
+### `shouldServe`
+
+An **optional** exported function that is only used by `now dev` in [Now CLI](https:///download) and indicates whether a [Builder](https://zeit.co/docs/v2/advanced/builders) wants to be responsible for building a certain request path.
+
+```js
+shouldServe({
+  entrypoint: String,
+  files: Files,
+  config: Object,
+  requestPath: String,
+  workPath: String
+}) : Boolean
+```
+
+If you are using TypeScript, you can import the types for each of these functions by using the following:
+
+```ts
+import { ShouldServeOptions } from '@now/build-utils'
+
+export shouldServe(options: ShouldServeOptions) {
+  return Boolean
+}
+```
+
+If this method is not defined, Now CLI will default to [this function](https://github.com/zeit/now-builders/blob/52994bfe26c5f4f179bdb49783ee57ce19334631/packages/now-build-utils/src/should-serve.ts).
+
+### Builder Options
+
+The exported functions [`analyze`](#analyze), [`build`](#build), and [`prepareCache`](#preparecache) receive one argument with the following properties.
+
+**Properties:**
+
+- `files`: All source files of the project as a [Files](#files) data structure.
+- `entrypoint`: Name of entrypoint file for this particular build job. Value `files[entrypoint]` is guaranteed to exist and be a valid [File](#files) reference. `entrypoint` is always a discrete file and never a glob, since globs are expanded into separate builds at deployment time.
+- `workPath`: A writable temporary directory where you are encouraged to perform your build process. This directory will be populated with the restored cache from the previous run (if any) for [`analyze`](#analyze) and [`build`](#build).
+- `cachePath`: A writable temporary directory where you can build a cache for the next run. This is only passed to `prepareCache`.
+- `config`: An arbitrary object passed from by the user in the [Build definition](#defining-the-build-step) in `now.json`.
+
+## Example: html-minifier
+
+Let's walk through what it takes to create a simple builder that takes in a HTML source file and yields a minified HTML static file as its build output.
+
+While this is a very simple builder, the approach demonstrated here can be used to return anything: one or more static files and/or one or more lambdas.
+
+## Setting up the module
+
+### Defining the analyze step
+
+The `analyze` hook is optional. Its goal is to give the developer a tool to avoid wasting time _re-computing a build_ that has already occurred.
+
+The return value of `analyze` is a _fingerprint_: a simple string that uniquely identifies the build process.
+
+If `analyze` is not specified, its behavior is to use as the fingerprint the combined checksums of **all the files in the same directory level as the entrypoint**. This is a default that errs on making sure that we re-execute builds when files _other than the entrypoint_ (like dependencies, manifest files, etc) have changed.
+
+For our `html-minify` example, we know that HTML files don't have dependencies. Therefore, our analyze step can just return the `digest` of the entrypoint.
+
+Our `index.js` file looks as follows:
+
+```js
+exports.analyze = function({ files, entrypoint }) {
+  return files[entrypoint].digest
+}
+```
+
+This means that we will only re-minify and re-create the build output _only if the file contents (and therefore its digest) change._
+
+### Defining the build step
+
+Your module will need some utilities to manipulate the data structures we pass you, create new ones and alter the filesystem.
+
+To that end, we expose our API as part of a `@now/build-utils` package. This package is always loaded on your behalf, so make sure it's only included as `peerDependencies` in your `package.json`.
+
+Builders can include dependencies of their liking:
+
+```js
+const htmlMinifier = require('html-minifier')
+
+exports.version = 2
+
+exports.analyze = ({ files, entrypoint }) => files[entrypoint].digest
+
+exports.build = async ({ files, entrypoint, config }) => {
+  const stream = files[entrypoint].toStream()
+  const options = Object.assign({}, config || {})
+  const { data } = await FileBlob.fromStream({ stream })
+  const content = data.toString()
+  const minified = htmlMinifier(content, options)
+  const result = new FileBlob({ data: minified })
+
+  return {
+    output: {
+      [entrypoint]: result
+    },
+    watch: [],
+    routes: {}
+  }
+}
+```
+
+### Defining a `prepareCache` step
+
+If our builder had performed work that could be re-used in the next build invocation, we could define a `prepareCache` step.
+
+In this case, there are not intermediate artifacts that we can cache, and our `analyze` step already takes care of caching the full output based on the fingerprint of the input.
+
+## Technical Details
+
+### Execution Context
+
+A [Serverless Function](https://zeit.co/docs/v2/advanced/concepts/lambdas) is created where the builder logic is executed. The lambda is run using the Node.js 8 runtime. A brand new sandbox is created for each deployment, for security reasons. The sandbox is cleaned up between executions to ensure no lingering temporary files are shared from build to build.
+
+All the APIs you export ([`analyze`](#analyze), [`build`](#build) and [`prepareCache`](#preparecache)) are not guaranteed to be run in the same process, but the filesystem we expose (e.g.: `workPath` and the results of calling [`getWriteableDirectory`](#getWriteableDirectory) ) is retained.
+
+If you need to share state between those steps, use the filesystem.
+
+### Directory and Cache Lifecycle
+
+When a new build is created, we pre-populate the `workPath` supplied to `analyze` with the results of the `prepareCache` step of the previous build.
+
+The `analyze` step can modify that directory, and it will not be re-created when it's supplied to `build` and `prepareCache`.
+
+To learn how the cache key is computed and invalidated, refer to the [overview](https://zeit.co/docs/v2/advanced/builders#technical-details).
+
+### Accessing Environment and Secrets
+
+The env and secrets specified by the user as `build.env` are passed to the builder process. This means you can access user env via `process.env` in Node.js.
+
+### Utilities as peerDependencies
+
+When you publish your builder to npm, make sure to not specify `@now/build-utils` (as seen below in the API definitions) as a dependency, but rather as part of `peerDependencies`.
+
+## Types
+
+### `Files`
+
+```ts
+import { File } from '@now/build-utils'
+type Files = { [filePath: string]: File }
+```
+
+This is an abstract type that is implemented as a plain [JavaScript Object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object). It's helpful to think of it as a virtual filesystem representation.
+
+When used as an input, the `Files` object will only contain `FileRefs`. When `Files` is an output, it may consist of `Lambda` (Serverless Functions) types as well as `FileRefs`.
+
+An example of a valid output `Files` object is:
+
+```json
+{
+  "index.html": FileRef,
+  "api/index.js": Lambda
+}
+```
+
+### `File`
+
+This is an abstract type that can be imported if you are using TypeScript.
+
+```ts
+import { File } from '@now/build-utils'
+```
+
+Valid `File` types include:
+
+- [`FileRef`](#fileref)
+- [`FileFsRef`](#filefsref)
+- [`FileBlob`](#fileblob)
+
+### `FileRef`
+
+```ts
+import { FileRef } from '@now/build-utils'
+```
+
+This is a [JavaScript class](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes) that represents an abstract file instance stored in our platform, based on the file identifier string (its checksum). When a `Files` object is passed as an input to `analyze` or `build`, all its values will be instances of `FileRef`.
+
+**Properties:**
+
+- `mode : Number` file mode
+- `digest : String` a checksum that represents the file
+
+**Methods:**
+
+- `toStream() : Stream` creates a [Stream](https://nodejs.org/api/stream.html) of the file body
+
+### `FileFsRef`
+
+```ts
+import { FileFsRef } from '@now/build-utils'
+```
+
+This is a [JavaScript class](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes) that represents an abstract instance of a file present in the filesystem that the build process is executing in.
+
+**Properties:**
+
+- `mode : Number` file mode
+- `fsPath : String` the absolute path of the file in file system
+
+**Methods:**
+
+- `static async fromStream({ mode : Number, stream : Stream, fsPath : String }) : FileFsRef` creates an instance of a [FileFsRef](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object) from `Stream`, placing file at `fsPath` with `mode`
+- `toStream() : Stream` creates a [Stream](https://nodejs.org/api/stream.html) of the file body
+
+### `FileBlob`
+
+```ts
+import { FileBlob } from '@now/build-utils'
+```
+
+This is a [JavaScript class](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes) that represents an abstract instance of a file present in memory.
+
+**Properties:**
+
+- `mode : Number` file mode
+- `data : String | Buffer` the body of the file
+
+**Methods:**
+
+- `static async fromStream({ mode : Number, stream : Stream }) :FileBlob` creates an instance of a [FileBlob](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object) from [`Stream`](https://nodejs.org/api/stream.html) with `mode`
+- `toStream() : Stream` creates a [Stream](https://nodejs.org/api/stream.html) of the file body
+
+### `Lambda`
+
+```ts
+import { Lambda } from '@now/build-utils'
+```
+
+This is a [JavaScript class](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes), called a Serverless Function, that can be created by supplying `files`, `handler`, `runtime`, and `environment` as an object to the [`createLambda`](#createlambda) helper. The instances of this class should not be created directly. Instead use a call to [`createLambda`](#createlambda).
+
+**Properties:**
+
+- `files : Files` the internal filesystem of the lambda
+- `handler : String` path to handler file and (optionally) a function name it exports
+- `runtime : LambdaRuntime` the name of the lambda runtime
+- `environment : Object` key-value map of handler-related (aside of those passed by user) environment variables
+
+### `LambdaRuntime`
+
+This is an abstract enumeration type that is implemented by one of the following possible `String` values:
+
+- `nodejs10.x`
+- `nodejs8.10`
+- `go1.x`
+- `java-1.8.0-openjdk`
+- `python3.6`
+- `python2.7`
+- `dotnetcore2.1`
+- `dotnetcore2.0`
+- `dotnetcore1.0`
+
+## JavaScript API
+
+The following is exposed by `@now/build-utils` to simplify the process of writing Builders, manipulating the file system, using the above types, etc.
+
+### `createLambda`
+
+Signature: `createLambda(Object spec) : Lambda`
+
+```ts
+import { createLambda } from '@now/build-utils'
+```
+
+Constructor for the [`Lambda`](#lambda) type.
+
+```js
+const { createLambda, FileBlob } = require('@now/build-utils')
+await createLambda({
+  runtime: 'nodejs8.10',
+  handler: 'index.main',
+  files: {
+    'index.js': new FileBlob({ data: 'exports.main = () => {}' })
+  }
+})
+```
+
+### `download`
+
+Signature: `download() : Files`
+
+```ts
+import { download } from '@now/build-utils'
+```
+
+This utility allows you to download the contents of a [`Files`](#files) data structure, therefore creating the filesystem represented in it.
+
+Since `Files` is an abstract way of representing files, you can think of `download` as a way of making that virtual filesystem _real_.
+
+If the **optional** `meta` property is passed (the argument for [build](#build)), only the files that have changed are downloaded. This is decided using `filesRemoved` and `filesChanged` inside that object.
+
+```js
+await download(files, workPath, meta)
+```
+
+### `glob`
+
+Signature: `glob() : Files`
+
+```ts
+import { glob } from '@now/build-utils'
+```
+
+This utility allows you to _scan_ the filesystem and return a [`Files`](#files) representation of the matched glob search string. It can be thought of as the reverse of [`download`](#download).
+
+The following trivial example downloads everything to the filesystem, only to return it back (therefore just re-creating the passed-in [`Files`](#files)):
+
+```js
+const { glob, download } = require('@now/build-utils')
+
+exports.build = ({ files, workPath }) => {
+  await download(files, workPath)
+  return glob('**', workPath)
+}
+```
+
+### `getWriteableDirectory`
+
+Signature: `getWriteableDirectory() : String`
+
+```ts
+import { getWriteableDirectory } from '@now/build-utils'
+```
+
+In some occasions, you might want to write to a temporary directory.
+
+### `rename`
+
+Signature: `rename(Files) : Files`
+
+```ts
+import { rename } from '@now/build-utils'
+```
+
+Renames the keys of the [`Files`](#files) object, which represent the paths. For example, to remove the `*.go` suffix you can use:
+
+```js
+const rename = require('@now/build-utils')
+const originalFiles = { 'one.go': fileFsRef1, 'two.go': fileFsRef2 }
+const renamedFiles = rename(originalFiles, path => path.replace(/\.go$/, '')
+```
