+# easyjson [![Build Status](https://travis-ci.org/mailru/easyjson.svg?branch=master)](https://travis-ci.org/mailru/easyjson) [![Go Report Card](https://goreportcard.com/badge/github.com/mailru/easyjson)](https://goreportcard.com/report/github.com/mailru/easyjson)
+
+Package easyjson provides a fast and easy way to marshal/unmarshal Go structs
+to/from JSON without the use of reflection. In performance tests, easyjson
+outperforms the standard `encoding/json` package by a factor of 4-5x, and other
+JSON encoding packages by a factor of 2-3x.
+
+easyjson aims to keep generated Go code simple enough so that it can be easily
+optimized or fixed. Another goal is to provide users with the ability to
+customize the generated code by providing options not available with the
+standard `encoding/json` package, such as generating "snake_case" names or
+enabling `omitempty` behavior by default.
+
+## Usage
+```sh
+# install
+go get -u github.com/mailru/easyjson/...
+
+# run
+easyjson -all <file>.go
+```
+
+The above will generate `<file>_easyjson.go` containing the appropriate marshaler and
+unmarshaler funcs for all structs contained in `<file>.go`.
+
+Please note that easyjson requires a full Go build environment and the `GOPATH`
+environment variable to be set. This is because easyjson code generation
+invokes `go run` on a temporary file (an approach to code generation borrowed
+from [ffjson](https://github.com/pquerna/ffjson)).
+
+## Options
+```txt
+Usage of easyjson:
+  -all
+    	generate marshaler/unmarshalers for all structs in a file
+  -build_tags string
+    	build tags to add to generated file
+  -leave_temps
+    	do not delete temporary files
+  -no_std_marshalers
+    	don't generate MarshalJSON/UnmarshalJSON funcs
+  -noformat
+    	do not run 'gofmt -w' on output file
+  -omit_empty
+    	omit empty fields by default
+  -output_filename string
+    	specify the filename of the output
+  -pkg
+    	process the whole package instead of just the given file
+  -snake_case
+    	use snake_case names instead of CamelCase by default
+  -stubs
+    	only generate stubs for marshaler/unmarshaler funcs
+```
+
+Using `-all` will generate marshalers/unmarshalers for all Go structs in the
+file. If `-all` is not provided, then only those structs whose preceeding
+comment starts with `easyjson:json` will have marshalers/unmarshalers
+generated. For example:
+
+```go
+//easyjson:json
+struct A{}
+```
+
+Additional option notes:
+
+* `-snake_case` tells easyjson to generate snake\_case field names by default
+  (unless overridden by a field tag). The CamelCase to snake\_case conversion
+  algorithm should work in most cases (ie, HTTPVersion will be converted to
+  "http_version").
+
+* `-build_tags` will add the specified build tags to generated Go sources.
+
+## Generated Marshaler/Unmarshaler Funcs
+
+For Go struct types, easyjson generates the funcs `MarshalEasyJSON` /
+`UnmarshalEasyJSON` for marshaling/unmarshaling JSON. In turn, these satisify
+the `easyjson.Marshaler` and `easyjson.Unmarshaler` interfaces and when used in
+conjunction with `easyjson.Marshal` / `easyjson.Unmarshal` avoid unnecessary
+reflection / type assertions during marshaling/unmarshaling to/from JSON for Go
+structs.
+
+easyjson also generates `MarshalJSON` and `UnmarshalJSON` funcs for Go struct
+types compatible with the standard `json.Marshaler` and `json.Unmarshaler`
+interfaces. Please be aware that using the standard `json.Marshal` /
+`json.Unmarshal` for marshaling/unmarshaling will incur a significant
+performance penalty when compared to using `easyjson.Marshal` /
+`easyjson.Unmarshal`.
+
+Additionally, easyjson exposes utility funcs that use the `MarshalEasyJSON` and
+`UnmarshalEasyJSON` for marshaling/unmarshaling to and from standard readers
+and writers. For example, easyjson provides `easyjson.MarshalToHTTPResponseWriter`
+which marshals to the standard `http.ResponseWriter`. Please see the [GoDoc
+listing](https://godoc.org/github.com/mailru/easyjson) for the full listing of
+utility funcs that are available.
+
+## Controlling easyjson Marshaling and Unmarshaling Behavior
+
+Go types can provide their own `MarshalEasyJSON` and `UnmarshalEasyJSON` funcs
+that satisify the `easyjson.Marshaler` / `easyjson.Unmarshaler` interfaces.
+These will be used by `easyjson.Marshal` and `easyjson.Unmarshal` when defined
+for a Go type.
+
+Go types can also satisify the `easyjson.Optional` interface, which allows the
+type to define its own `omitempty` logic.
+
+## Type Wrappers
+
+easyjson provides additional type wrappers defined in the `easyjson/opt`
+package. These wrap the standard Go primitives and in turn satisify the
+easyjson interfaces.
+
+The `easyjson/opt` type wrappers are useful when needing to distinguish between
+a missing value and/or when needing to specifying a default value. Type
+wrappers allow easyjson to avoid additional pointers and heap allocations and
+can significantly increase performance when used properly.
+
+## Memory Pooling
+
+easyjson uses a buffer pool that allocates data in increasing chunks from 128
+to 32768 bytes. Chunks of 512 bytes and larger will be reused with the help of
+`sync.Pool`. The maximum size of a chunk is bounded to reduce redundant memory
+allocation and to allow larger reusable buffers.
+
+easyjson's custom allocation buffer pool is defined in the `easyjson/buffer`
+package, and the default behavior pool behavior can be modified (if necessary)
+through a call to `buffer.Init()` prior to any marshaling or unmarshaling.
+Please see the [GoDoc listing](https://godoc.org/github.com/mailru/easyjson/buffer)
+for more information.
+
+## Issues, Notes, and Limitations
+
+* easyjson is still early in its development. As such, there are likely to be
+  bugs and missing features when compared to `encoding/json`. In the case of a
+  missing feature or bug, please create a GitHub issue. Pull requests are
+  welcome!
+
+* Unlike `encoding/json`, object keys are case-sensitive. Case-insensitive
+  matching is not currently provided due to the significant performance hit
+  when doing case-insensitive key matching. In the future, case-insensitive
+  object key matching may be provided via an option to the generator.
+
+* easyjson makes use of `unsafe`, which simplifies the code and
+  provides significant performance benefits by allowing no-copy
+  conversion from `[]byte` to `string`. That said, `unsafe` is used
+  only when unmarshaling and parsing JSON, and any `unsafe` operations
+  / memory allocations done will be safely deallocated by
+  easyjson. Set the build tag `easyjson_nounsafe` to compile it
+  without `unsafe`.
+
+* easyjson is compatible with Google App Engine. The `appengine` build
+  tag (set by App Engine's environment) will automatically disable the
+  use of `unsafe`, which is not allowed in App Engine's Standard
+  Environment. Note that the use with App Engine is still experimental.
+
+* Floats are formatted using the default precision from Go's `strconv` package.
+  As such, easyjson will not correctly handle high precision floats when
+  marshaling/unmarshaling JSON. Note, however, that there are very few/limited
+  uses where this behavior is not sufficient for general use. That said, a
+  different package may be needed if precise marshaling/unmarshaling of high
+  precision floats to/from JSON is required.
+
+* While unmarshaling, the JSON parser does the minimal amount of work needed to
+  skip over unmatching parens, and as such full validation is not done for the
+  entire JSON value being unmarshaled/parsed.
+
+* Currently there is no true streaming support for encoding/decoding as
+  typically for many uses/protocols the final, marshaled length of the JSON
+  needs to be known prior to sending the data. Currently this is not possible
+  with easyjson's architecture.
+
+## Benchmarks
+
+Most benchmarks were done using the example
+[13kB example JSON](https://dev.twitter.com/rest/reference/get/search/tweets)
+(9k after eliminating whitespace). This example is similar to real-world data,
+is well-structured, and contains a healthy variety of different types, making
+it ideal for JSON serialization benchmarks.
+
+Note:
+
+* For small request benchmarks, an 80 byte portion of the above example was
+  used.
+
+* For large request marshaling benchmarks, a struct containing 50 regular
+  samples was used, making a ~500kB output JSON.
+
+* Benchmarks are showing the results of easyjson's default behaviour,
+  which makes use of `unsafe`.
+
+Benchmarks are available in the repository and can be run by invoking `make`.
+
+### easyjson vs. encoding/json
+
+easyjson is roughly 5-6 times faster than the standard `encoding/json` for
+unmarshaling, and 3-4 times faster for non-concurrent marshaling. Concurrent
+marshaling is 6-7x faster if marshaling to a writer.
+
+### easyjson vs. ffjson
+
+easyjson uses the same approach for JSON marshaling as
+[ffjson](https://github.com/pquerna/ffjson), but takes a significantly
+different approach to lexing and parsing JSON during unmarshaling. This means
+easyjson is roughly 2-3x faster for unmarshaling and 1.5-2x faster for
+non-concurrent unmarshaling.
+
+As of this writing, `ffjson` seems to have issues when used concurrently:
+specifically, large request pooling hurts `ffjson`'s performance and causes
+scalability issues. These issues with `ffjson` can likely be fixed, but as of
+writing remain outstanding/known issues with `ffjson`.
+
+easyjson and `ffjson` have similar performance for small requests, however
+easyjson outperforms `ffjson` by roughly 2-5x times for large requests when
+used with a writer.
+
+### easyjson vs. go/codec
+
+[go/codec](https://github.com/ugorji/go) provides
+compile-time helpers for JSON generation. In this case, helpers do not work
+like marshalers as they are encoding-independent.
+
+easyjson is generally 2x faster than `go/codec` for non-concurrent benchmarks
+and about 3x faster for concurrent encoding (without marshaling to a writer).
+
+In an attempt to measure marshaling performance of `go/codec` (as opposed to
+allocations/memcpy/writer interface invocations), a benchmark was done with
+resetting length of a byte slice rather than resetting the whole slice to nil.
+However, the optimization in this exact form may not be applicable in practice,
+since the memory is not freed between marshaling operations.
+
+### easyjson vs 'ujson' python module
+
+[ujson](https://github.com/esnme/ultrajson) is using C code for parsing, so it
+is interesting to see how plain golang compares to that. It is imporant to note
+that the resulting object for python is slower to access, since the library
+parses JSON object into dictionaries.
+
+easyjson is slightly faster for unmarshaling and 2-3x faster than `ujson` for
+marshaling.
+
+### Benchmark Results
+
+`ffjson` results are from February 4th, 2016, using the latest `ffjson` and go1.6.
+`go/codec` results are from March 4th, 2016, using the latest `go/codec` and go1.6.
