A mixin to set id to shortid for a loopback Model.
npm i --save loopback-shortid-mixinThere are 2 ways to enable mixin:
In your server/server.js file add the following line before the boot(app, __dirname); line.
...
var app = module.exports = loopback();
...
// Add shortid Mixin to loopback
require('loopback-shortid-mixin')(app);
boot(app, __dirname, function(err) {
'use strict';
if (err) throw err;
// start the server if `$ node server.js`
if (require.main === module)
app.start();
});- mixin sources
Add the mixins property to your server/model-config.json like the following:
{
"_meta": {
"sources": [
"loopback/common/models",
"loopback/server/models",
"../common/models",
"./models"
],
"mixins": [
"loopback/common/mixins",
"loopback/server/mixins",
"../node_modules/loopback-shortid-mixin",
"../common/mixins",
"./mixins"
]
}
}To use with your Models add the mixins attribute to the definition object of your model config.
