Tresor

⚠️ WIP ⚠️

A tool to fetch data from the Trello API and store them locally as static JSON files.

With Tresor you can use Trello as a redactional UI and content managment system. It will transform a Trello list into a set of static JSON files ready to be served as an API for a static website.

Why ?

This is a tool to build your next JAMstack project, allowing your codebase to be entirely static and serverless, but also has the advantages of a content management system, as your site will be automatically updated when the content changes. A static files codebase can be entirely hosted on a CDN, reducing infrastructure costs and increasing performance and availability.

Trello offers a very simple UI and a well designed API, with all necessary features to manage the content behind a small static website, a blog or a single page application:

• Markdown support
• Attachments: files upload, render images in different resolutions and render thumbnails
• Labels: can be used as tags or categories
• Members: can be used to assign an entry to an author
• Emoji support !
• ...

How it works ?

Tresor reads the Trello API and saves the results locally as static JSON files, in a folder structure that allows to consume the data as HTTP API endpoints. The static files can be either copied in the client build folder or hosted somewhere else (CDNs, Github Pages, Netlify, ...), so that the client can then consume the data in a RESTful way.

Setting up Continous Delivery it is then possible to configure a Webhook to trigger a new build when the content served from you API is changed.

Installation

(Skip this using npx)

Requirements:

• Node.js >= v8
• npm >= v5

Run:

npm install tresor

Usage

Requirements:

• Trello API Key and the API Token: can be requested here
• ID of the list (column) to turn into a set of static JSON files. If you want for example to work on the list Public from the board https://trello.com/b/dhhEnV8b/tresor-example, just open the JSON representation at https://trello.com/b/dhhEnV8b.json and search for the Public list. You will find the ID in an object like the following: {"name":"Public","id":"5b193b1a8a23ebb893ab7a02"}

You can pass the API Key, the API Token, the list ID and any other option as:

• environment variables
• command-line arguments
• property of the config.json file

Run the following command to download the JSON files:

tresor

Passing the config options as environment variables:

API__KEY=asenoiuwqeWNEUfnewoeFNWQetr3295023rer API__TOKEN=ASnqoiwqenmNEWOIWNrffnklef3io2r032rnewfoid3T439543 API__LIST=124f9hue2983232rj32052s tresor

or as command-line arguments:

tresor --api.key=asenoiuwqeWNEUfnewoeFNWQetr3295023rer --api.token=ASnqoiwqenmNEWOIWNrffnklef3io2r032rnewfoid3T439543 --api.list=124f9hue2983232rj32052s

Options

The options you can add to the config.json file or pass via command-line/environment variables are:

Name	Description	Default
api.url	The base API url	"https://api.trello.com/1/"
api.key	The API key (required)
api.token	The API token (required)
api.list	The IDs (as array) of the trello lists to watch (required)
dest.root	The folder where all JSON files are saved	"static/"
dest.all	The filename of the JSON containings all entries	"all.json"
dest.tags	The filename of the JSON containings all tags	"tags.json"
dest.post	The folder name where all single posts are saved	"post"

fields.attachments	Display or not attachments information (true or false)	true

The default config.json file looks like the following one:

{
    "api": {
        "url": "https://api.trello.com/1/"
    },
    "dest": {
        "root": "static",

npx

This module is suitable to be used with npx, so that you don't need to install the module and add it to your package dependencies. Just add npx tresor to your prebuild hook in the package.json of your module:

{
  [...]
  "scripts": {
    "prebuild": "npx tresor",
  [...]
  }
}

Done!
