Opinionated project generator for node.js relying on express, jade, stylus, Bootstrap 3, and mongoose.
Truss is an opinionated scaffolding tool for node.js that originated from bumm. Bumm is great but I wish to take Truss in a different direction. There may have been a good reason to call the tool "bumm" but I never understood it. "Truss" on the other hand is a construction term, similar to but not the same as scaffolding.
truss /trəs/ noun a framework, typically consisting of rafters, posts, and struts, supporting a roof, bridge, or other structure
npm install truss -g
First cd to the directory where the project should be created
Create a project skeleton via
truss app testapp
Next cd to testapp
And install required packages through npm
Create a model, route and views via
scaffold command. The model
should have two properties "title" and "description" where title is required.
truss scaffold test title:string:required:true description
Model validators are specified after property name and type in plain mongoose syntax. In case no type is specified the property will be of type string.
Mongoose types 'String', 'Number', 'Date', 'Buffer', 'Boolean', 'ObjectId', 'Array' are supported. Additionally the types 'Datetime' and 'Textarea' are supported which result in a datetime html 5 input tag and a textbox tag. Types are case insensitive.

You can create a JSON REST endpoint by scaffolding a model and its corresponding routes. The arguments are the same as above, but instead of scaffold use scafffold:rest like this

Creates and initializes an express app with a mongoDb connection configured. Routes will be setup by requiring the routes directory directly. See routes below.
Defines some jade/html helpers for displaying error messages and displaying values.

The config directory is required by
app.js to load the configuration files. Truss assumes that you have three config files
Truss loads defaults first, then loads the configuration file
production depending on the current
environment variable and overrides all default values with the development or production values.
Truss ships with a single library file that is responsible to map values provided in request body to a mongoose model.
vendor directory and follows a
for vendor libraries. You are free to place your libraries wherever you want :)
All generated routes will be generated under routes. After creating an app with Truss, you'll find a single
index.js file in
this folder. Index.js requires all files that are in or routes or a sub directory of routes to initialize the route. In case
you require a route to be defined before another route you can always require that route in
index.js or load routes manually
in a defined order.
index.js also defines a route to
/ to render a nice getting started page. This functionality can be removed without harming
All generated view will be generated under views. After creating an app with Truss, you'll find an index.jade that is a welcome file to display some help text or defined routes, a layout.jade file that defines the layout used by all generated views and a mixin folder that defines mixins used in Truss generated views.
