Expressive fixtures generator for Loopback
npm install loopback-fixturesExpressive fixtures generator for Loopback
``
npm install --save loopback-fixtures
Then, in your server/component-config.json, add :
` json`
{
"loopback-fixtures": {
"fixturePath": "/fixtures/data/",
"append": false,
"autoLoad": false
}
}
Write your YML fixture file /fixture/data/data.yml (adapt according your model) :
` yaml
Group:
group{1..10}:
name: "Groupe {@} depuis les fixtures"
User:
user{1..10}:
name: "User {@} : {{name.lastName}}"
groupId: @group{@}
email: "{{internet.email}}"
birthDate: "2016-01-01"
favoriteNumber: "(function() { return Math.round(Math.random()*1000);})()"
`
- If autoLoad is set to true, fixtures will be loaded when you start your application
- With the server:
app.loadFixtures() (return a promise)
e.g:
` js`
app.loadFixtures()
.then(function() {
console.log('Done!');
})
.catch(function(err) {
console.log('Errors:', err);
});
- With a node command:
`
./node_modules/loopback-fixtures/lib/load-fixtures.js
- fixturePath (default value '/fixtures/data')
The directory to load data fixtures from
- append (default value false)
If set to true, data fixtures will be append instead of deleting all data from the database first.false
WARNING will erase your database
- autoLoad (default value false)
- Load data according your model
- Multiple generators :
` yaml`
User:
user{1..45}:
name: "User number {@}"
{@} represents the current identifier for the generator
- References :
` yaml
Group:
group{1..3}:
name: "Groupe number {@}"
User:
user{1..9}:
name: "User number {@}"
group: @group1 # Reference to group1
user{10..19}:
name: "User number {@}"
group: @group.* # Reference to any matching group
`
@group1 represents the reference for the group1 and can be used in other fixtures@group.*

` yaml`
User:
user{1..10}:
name: "User n°{@} : {{name.lastName}} {{name.firstName}}"
email: "{{internet.email}}"
You can use Faker.js API to provide fake data

` yaml``
User:
user{1..10}:
favoriteNumber: "(function() { return Math.round(Math.random()*1000);})()"
You can use custom functions too
