Notoriously Psychedelic Modules

    fancyshelf

    0.0.1 • Public • Published

    fancyshelf

    A friendly wrapper for Bookshelf. The goal is to have an API that is so consistent, predictable and logical that you won't even really need to read the documentation to use it.

    The registry and virtuals plugins in Bookshelf are enabled by default when using fancyshelf.

    CAUTION!

    This is very much not suitable for production use yet. You should not use this module unless you know what you are doing.

    It is very possible that this module will never make it to a 'real' release. A redesign of Bookshelf is ongoing, and I am planning on my own experimental ORM as well.

    Consider this module to be a temporary band-aid until something better is available.

    Instantiating

    var shelf = require("fancyshelf")({
        engine: "mysql2",  /* Optional The database engine to use. Defaults to `mysql2`. */
        host: "localhost",  /* The hostname that the database runs on. */
        username: "my_site"  /* the database username to use. */
        password: "thisisnotasecurepassword",  /* The password... */
        database: "my_site",  /* The database to use. */
        charset: "utf8",  /* Optional. The character set to use. Defaults to 'utf8'. */
        debug: true  /* Whether to output debug information. Don't use in production. */
    });

    Using with Express

    express.use(shelf.express);

    Non-Express fancyshelf API

    Mostly the same as for bookshelf.

    shelf.connection

    The underlying knex instance.

    shelf.modelQuery(modelName, queryFunc)

    See the documentation for req.modelQuery.

    Express middleware API

    All fancyshelf-related attributes exist on the req object.

    req.db

    This attribute contains the underlying fancyshelf object.

    req.db.connection

    The underlying knex instance for the fancyshelf object. It's useful for raw queries.

    req.model(modelName[, modelDefinition])

    Retrieves an existing model or, if a modelDefinition is specified, creates a new one under the given modelName.

    req.modelQuery(modelName, queryFunc)

    Shorthand method for retrieving a model and defining a query on it. Specify a callback as queryFunc - this callback will receive the Knex querybuilder for the model as its first argument, on which you can then operate.

    Exceptions

    shelf.NotFoundError / req.db.NotFoundError

    This exception is thrown when an attempt to retrieve a single model fails.

    shelf.EmptyResponse / req.db.EmptyResponse

    This exception is thrown when an attempt to retrieve a collection of models fails.

    Model querying API

    This API is available to any model originating from a req.model call.

    model.find(id[, withRelations, options])

    Attempts to retrieve a model with the given id from the database. If the given model cannot be found, an error will be thrown (if you don't want this, use findOptional).

    You can use withRelations to specify an array or map of relations to retrieve, and options for specifying standard Bookshelf query options to use.

    Returns a populated model.

    model.findOptional(id[, withRelations, options])

    The same as model.find, but does not throw an error if the model is not found in the database.

    Returns a populated model when found, or an empty model when not found.

    model.getOneWhere(conditions[, withRelations, options])

    Retrieves a single model from the database whose attributes match all conditions. Unspecified attributes are not taken into account.

    Accepts withRelations and options like model.find.

    Returns a populated model when found.

    model.getAllWhere(conditions[, withRelations, options])

    Retrieves all models from the database whose attributes match all conditions. Unspecified attributes are not taken into account.

    Accepts withRelations and options like model.find.

    Returns a collection of populated models when found.

    model.getCountWhere(conditions[, withRelations, options])

    Retrieves the number of models in the database whose attributes match all conditions. Unspecified attributes are not taken into account.

    Accepts withRelations and options like model.find.

    Returns the number of matches (ie. COUNT).

    model.getOneFromQuery(queryFunc[, withRelations, options])

    Retrieves a single model from the database that is matched by the specified queryFunc (as in req.modelQuery).

    Accepts withRelations and options like model.find.

    Returns a populated model when found.

    model.getAllFromQuery(queryFunc[, withRelations, options])

    Retrieves all models from the database that are matched by the specified queryFunc (as in req.modelQuery).

    Accepts withRelations and options like model.find.

    Returns a collection of populated models when found.

    model.getCountFromQuery(queryFunc[, withRelations, options])

    Retrieves the number of models in the database that are matched by the specified queryFunc (as in req.modelQuery).

    Accepts withRelations and options like model.find.

    Returns the number of matches (ie. COUNT).

    model.getAll([options])

    Retrieves all models in the database. Accepts options like model.find.

    model.countAll([options])

    Returns the amount of models in the database. Accepts options like model.find.

    Model retrieval API

    These functions may be useful when you're building a model query manually, and still want to take advantage of fancyshelf's syntax.

    model.retrieve([withRelations, options])

    Retrieves one matching model from the database. Throws an error if none are found.

    Accepts withRelations and options like model.find.

    model.retrieveAll([withRelations, options])

    Retrieves all matching models from the database. Throws an error if none are found.

    Accepts withRelations and options like model.find.

    model.retrieveOptional([withRelations, options])

    Retrieves one matching model from the database. Silently fails.

    Accepts withRelations and options like model.find.

    model.retrieveAllOptional([withRelations, options])

    Retrieves all matching models from the database. Silently fails.

    Accepts withRelations and options like model.find.

    Model modification API

    This API is available to any populated model.

    model.saveChanges()

    Saves the model, but only the attributes that have changed.
