Adonis lucid is a SQL ORM built on top of knexjs. It is built on standards of Active Record pattern which become mainly popular with Ruby on Rails.
Apart from being just a query builder, Lucid has following features.
- ES6 classes based data Models.
- Model Hooks
- Associations
- Serializers ( Vanilla and JSON API )
- Migrations
- Factories and Seeds
The provider must be installed from npm using adonis
command.
adonis install @adonisjs/lucid
Post that make sure to read instructions.md file on how to setup the provider.
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
- Lint your code using standardJs. Run
npm run lint
command to check if there are any linting errors. - Make sure you write tests for all the changes/bug fixes.
- 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. - Make sure all the tests are passing on
travis
andappveyor
.
Since Es6 is in, you should strive to use latest features. For example:
- Use
Spread
overarguments
keyword. - Never use
bind
orcall
. After calling these methods, we cannot guarantee the scope of any methods and in AdonisJs codebase we do not override the methods scope. - Make sure to write proper docblock.
It is always helpful if we try to follow certain practices when creating issues or PR's, since it will save everyone's time.
- Always try creating regression tests when you find a bug (if possible).
- Share some context on what you are trying to do, with enough code to reproduce the issue.
- For general questions, please create a forum thread.
- When creating a PR for a feature, make sure to create a parallel PR for docs too.
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.
