Tadam 1 4
Tadam is a minimalistic framework for creating dynamic function-oriented websites. All the potential of Clojure simplified for fast development. It could be in someway equivalent to Flask, but a little more modern.
The rest of the magic will come from you.

1. Make sure you have Openjdk or Oracle-jdk installed.
Debian/Ubuntu
Mac OS
2. Install Clojure and Leiningen.
Debian/Ubuntu
Mac OS
3. Create a π©Tadamπ© project.
4. Run.
Great π. You already have your π₯ own web server π₯.
Now open your browser.
When you generate your project you will find the following structure.
Let's see the description of the relevant sections.
Root
| Name | Type | Description |
|---|---|---|
| config.yaml | File | The configuration of your application, to which you can add all the variables you need. By default you will find domain, debug and port. You can see more information in Configuration |
| project.clj | File | Clojure configuration. Add as many libraries as you need. |
| README.md | File | Example of README.md file for your project. |
Resources folder
Everything related to the template system or static files (javascript, images, styles...).
| Name | Type | Description |
|---|---|---|
| public | Folder | Static material. |
| templates | Folder | Templates HTML. |
| templates/layouts/base.html | File | Example of a template that will contain all the structure that will not change between pages, such as the header or footer. |
| templates/public/welcome.html | File | Sample HTML page. |
src folder
Source code in Clojure, the heart of the beast. System of routes, views, business logic...
| Name | Type | Description |
|---|---|---|
| views/ | Folder | The views are invoked by the urls.clj . When a route is visited, a function within the appropriate view is called. |
| views/public.clj | File | Example of a public view. In the future it should grow with other private, management, identification or APIs. |
| config.clj | File | Place to store the configuration. You can configure as many variables as you need or add them as root in config.yaml |
| core.clj | File | First file to be executed in your application. It must have the minimum to start. |
| urls.clj | File | Routes of your website. |
By default you will have a config.yaml file like the one below.
- domain: Indicates which will be the domain of your application (http://example.com). In case you work locally or have a reverse proxy, it will not be necessary to modify it.
- debug: If true, it enables an automatic code refresh and ignores CORS. Otherwise it assumes you are working in production and will block the CORS in accordance to the domain.
- port: Port you will use.
Feel free to add as many variables as you need.
For example let's create the wizard variable and use it.
config.yaml
core.clj
Simple route
Tadam 1 4 X 4
Inside urls.clj you can find an example where 2 routes are declared and linked to their respective views.
If you want to add new routes you should follow 4 steps.
- Import the View.
- Use or create a group of Routes.
- Define the routes with View.
- Add your group to the set of all routes (Optional, only if it does not exist). You should always leave at the end resources-routes, are used for static content.
Parameters
In the following example we have routes that require different parameters.
In the View, the variables are collected as follows.
Avoiding repetition
At some point you will need to have a prefix for the routes.
To avoid this you can use a context.
The views are used to include the logic of each route.
In this example, an HTML template is rendered.
In the following example, a simple JSON is printed.
You can see more in Responses.
HTML templates can be displayed in raw, rendered using parameters or different layouts. As well as it is possible to return Markdown or JSON.
All templates should be located in /resources/templates/.
The syntax is inspired by Django. It is generated by Selmer, you can consult its documentation for more advanced topics such as loops or filters.
HTML
Suppose you have an HTML template in the /resources/templates/theatre.html path.
Then you just need to use the function render-HTML.
Example
HTML with params
Suppose you have an HTML template in the /resources/templates/theatre.html path.
The View would be similar to the previous example but indicating its parameters.
As a result the request is returned.
HTML in layout
In case you need to repeat the same HTML structure, then it is possible to extend a template or to define which part will change at each page HTML in layout.
Let's create a template in /resources/templates/layouts/base.html that will our reference to generate new ones. It will contain all the recurrent parts, such as header, footer, navs, etc. Then we define where should be added blocks that will be different at each page.
Now it's time to define the page that will extend base.html with new template in /resources/templates/public/welcome.html.
The result is:
Markdown
It is possible to use Markdown files that will be transformed into HTML.
JSON
There is a function available to convert collections to JSON.
Example
It returns a nice JSON with the right header.
Render templates to string
In certain circumstances it is necessary to render HTML templates to obtain a string, for example when we want to prepare content to send an email or because it is going to be saved in a new file.
Example
Params
GET
From the following URL we can capture the variable query.
POST
Tandem 14ft Utility
Capturing a parameter by POST is like GET.
If you need to know if you are receiving the POST method you can use:
JSON
A small utility can be used to obtain the parameters of a JSON.
HEADERS
If you need to capture the value of a header.
When used in a View the (render-HTML) function, or any other template element, it is not necessary to specify the request. In case you need to customize it you have a helper.
At least the request and the body must be indicated.
Return to browser.
Although it can be customized with status and content-type.
Return to browser.
Redirect
To make a redirect in your View you have within responses the utility redirect.
Example:
If he's not told otherwise, he'll use status 303 (See Other).
If you need another one, such as 301, you can customize the argument status.
Also redirect-permanent in case you want to use the 308 state directly, although it can also be done like the previous examples.
Example:
If you want to send emails before you must update the configuration variables in config.yaml.
Add the following.
Then all you have to do is use send-email.
Example:
You can do this easily by customizing the HTML or plain text with render-template.
Run the following command to build a jar file.
After this two files should be created in target/. We will use the standalone version: {project name}-standalone.jar.
Systemctl
To create a service in Linux is done like any application in Java. Below you can see an example.
Create a file in the following path: /etc/systemd/system/tadam-project.service.
Add the content.
Finally enable and start the service.
Nginx
With Nginx it's pretty quick and easy. You can use it as a reverse proxy, since Glosa contains its own web server (Jetty). You can see an example of configuration that can be useful.
Comments for static sites. Clone of Disqus, but faster, Opensource and sexy.
Free online service that tells you if a site is made with WordPress using proprietary techniques.
Do you want to know if a site is made with Tadam?
