Adonis BodyParser 🎯

This is the official body parser middleware for the Adonis framework. Apart from just reading the request body and files, it has really cool features.

NOTE: Only support Adonis4.0 or greater

NPM Version Build Status Appveyor Coveralls


  1. Support for url-encoded and multipart form bodies.
  2. Accepts JSON Patch [RFC6902]
  3. Accepts JSON API v1
  4. Accepts JSON csp-report
  5. Accepts raw text and buffers.
  6. Seamless support for nested arrays within the form body.
  7. Stream files directly to s3 using node-flydrive
  8. Conditionally consume uploaded files as streams.
  9. Set hard limits on server to deny request payload greater than x bytes.


The body parser is pre-configured with every new AdonisJs application. But in case you want to setup it manually.


npm i --save adonis-bodyparser


Make sure to register the provider inside start/app.js file.

const providers = [

Once the provider has been setup, it will automatically register a global middleware for you.

Node/OS Target

This repo/branch is supposed to run fine on all major OS platforms and targets Node.js >=7.0


Great! If you are planning to contribute to the framework, make sure to adhere to following conventions, since a consistent code-base is always joy to work with.

Run the following command to see list of available npm scripts.

npm run

Tests & Linting

  1. Lint your code using standardJs. Run npm run lint command to check if there are any linting errors.
  2. Make sure you write tests for all the changes/bug fixes.
  3. Also you can write regression tests, which shows that something is failing but doesn't breaks the build. Which is actually a nice way to show that something fails. Regression tests are written using test.failing() method.
  4. Make sure all the tests are passing on travis and appveyor.

General Practices

Since Es6 is in, you should strive to use latest features. For example:

  1. Use Spread over arguments keyword.
  2. Never use bind or call. After calling these methods, we cannot guarantee the scope of any methods and in AdonisJs codebase we do not override the methods scope.
  3. Make sure to write proper docblock.

Issues & PR

It is always helpful if we try to follow certain practices when creating issues or PR's, since it will save everyone's time.

  1. Always try creating regression tests when you find a bug (if possible).
  2. Share some context on what you are trying to do, with enough code to reproduce the issue.
  3. For general questions, please create a forum thread.
  4. When creating a PR for a feature, make sure to create a parallel PR for docs too.

Regression Tests

Regression tests are tests, which shows how a piece of code fails under certain circumstance, but the beauty is even after the failure, the test suite will never fail. Actually is a nice way to notify about bugs, but making sure everything is green.

The regression tests are created using

test.failing('2 + 2 is always 4, but add method returns 6', (assert) => {
 assert.true(add(2, 2), 4)

Now since the add method has a bug, it will return 6 instead of 4. But the build will pass.
