    🔥 FuegoJS 🔥

    Opinionated server-side rendering web framework built on Remix for AWS, using Terraform. The goal is to make your full stack web application and your experience developing it blazing fast! All configuration come with opinionated defaults.

    Project is still under heavy development. APIs are subject to change and there are bugs. Lots of them..

    The package exposes its commands as both a CLI and as a module to be imported in your script files. It's core commands could be thought of as the following matrix:

    |  🔥   |  Develop      |   Package       |      Ship       |
    | APP   | `fuego dev`   | `fuego build`   | `fuego deploy`  |
    | API   | `fuego api`   | `fuego compile` | `fuego upgrade` |
    | DATA  | `fuego sync`  | `fuego plan`    | `fuego apply`   |
    | NPM   | `fuego node`  | `fuego package` | `fuego publish` |
    | TESTS | `fuego watch` | `fuego test`    | `fuego report`  |

    This table represents the goal. The left column represents the potential targets of where your code gets shipped. Each target is a parent directory in a fuego repo. The following three columns represent the three core phases of the development cycle. The documentation below represents the current API which has not yet reached this vision. Project is still under heavy development!

    We will go through each layer in the application, and within each outline the three core phases in development in each. There are also various utilities available to help along the way.


    The APP is primarily built on Remix. It offers an opinionated approach on how Remix apps should be built when targeting AWS Cloudfront, while also taking care of a lot of the boilerplate. Your entire front end should live in the app directory.


    The dev command is a light wrapper around the Remix Dev command.

    fuego dev

    It supports the following arguments:

    • --port [number] - Sets the PORT environment variable that the Remix development server uses to run on. Default: 3000


    The build command is a light wrapper adound the Remix Build command. Because Remix doesn't currently support interpolating environment variables through something like a dotenv plugin, this command will run a second esbuild after the Remix one to interpolate those values, which gets built to the out/index.js.

    The command expects all app files to be within the /app directory. This includes the adapter file that Remix usually advises to keep in the root server folder, Fuego expects the file to be in the app/server directory. This is to follow the Fuego principle that each top level directory represents a different destination that code is shipped to.

    Public assets are currently expected in the root public directory, built to public/build. This is expected to migrate to app/public and app/public/build in a future version.

    fuego build

    The build command supports the following arguments:

    • --readable - It builds a readable version of the main server file for help debugging issues. Default: false


    The deploy command performs two major steps. First, it publishes everything from the public directory to the configured S3 bucket. Then, it compares a zip of the out directory with what's already deployed to the Origin Request Lambda associated with your Cloudfront Distribution. If the hashes of the zips match, no further action will be taken. If it differs, than it means the function has changes and needs to be deployed:

    • First, the zip of the out directory is uploaded to the lambda, with index.js renamed to origin-request.js.
    • Then, CloudFront is updated to associate the new version of the lambda's code with the distribution. The command will wait for this to finish.
    fuego deploy

    The deploy command supports the following arguments:

    • --domain [name] - The domain name of your web application. By default, it sets the value to the name of your repository.


    The API takes a serverless architecture approach, defining each file as a single function deployed to a single API path. It also supports deploying functions that are not part of your API but used for async processing. Because the APP above already includes its own backend, functions defined in API are meant to be accessible by other applications, not your APP.


    The api command runs a local api server that maps each of the functions built to the build directory to an API path. For example, the function example/get.ts will create a path GET /example in the API server. Functions defined at the root of the folder will be reachable at POST /[name]. It watches for edits of your functions in the api directory and rebuilds the requisite js files on edit, remapping the server handler. Each function should be exported as the handler named method.

    fuego api

    The api command supports the following arguments:

    • --tunnel [domain] - Uses ngrok to create a public URL gateway that tunnels into your API, useful for testing webhooks. Off by default.
    • --port [number] - The port your API will run on locally. Default: 3003


    The compile command reads all of the serverless functions that make up your backend api and outputs them as js files in the build directory. It expects all of your functions to be in the api directory in your repo. Each function file within a path must be named after an HTTP method: get.ts, post.ts, put.ts, & delete.ts. Functions found in the root could be named anything and will be deployed as background lambda functions.

    fuego compile

    The compile command supports the following arguments:

    • --readable - It builds a readable version of the main server file for help debugging issues. Default: false
    • --path [name] - The name of the root directory where you function files can be found in. Default: api


    The publish command reads the files from the build directory and deploys them to various AWS Lambdas. It expects the names of the AWS Lambda functions to be {NAME}_{FUNCTION} where NAME is the name of your backend API and FUNCTION is the name of your function, delimiting the parts of path with - instead of /. Special characters in NAME (e.g. .) will be replaced with a -.

    fuego publish

    The publish command supports the following arguments:

    • --name [name] - The name of your backend API. By default, it sets the value to the name of your repository.


    Most libraries that help manage your data assume a single data source - your database. Fuego takes the approach that the data in your application does live in multiple places and having all of those schemas version controlled in your codebase is the best way to keep track on how it evolves with your application. Schemas should be defined declaritively, allowing Fuego to reconcile differences automatically. The heavy lifting for this reconciliation is mostly done by Terraform. Fuego custom migrations are allowed as an escape hatch for anything not defined declaritively.


    Coming Soon! Currently requires running npx fuego migrate locally.


    Coming Soon! See npx fuego migrate --generate below.


    Coming Soon! See npx fuego migrate below.


    The migrate command that exists today allows users to define custom one time scripts to run on either their development or production environments. Migration files are currently expected to be in the data/migrations root directory. It also expects a DATABASE_URL environment variable to be defined to track migrations applied with mysql. Migration files themselves can be in typescript and should expose a migrate and revert functions, run while applying and reverting the migration respectively. Typescript allow migrations to include database migrations via sql queries and third party service data via API calls.

    Migrations should be viewed as an escape hatch for one time scripts run on production. There's almost always a better approach:

    • Schema migrations should instead be defined as Schema files (coming soon!)
    • Data migrations should instead be features in your application that could be run by users or admin
    npx fuego migrate

    The migrate command supports the following arguments:

    • --generate [name] - Creates a migration file in yyyy-MM-dd-hh-mm-name.ts format instead of running migrations.
    • --revert [number] - Reverts the last number of migration files instead of running migrations. No argument defaults number to 1.
    • --overwrite [name] - Overwrites the checksum of the migration file specified by name in case any changes are made, before running migrations. By default, if fuego detects differences in checksum, the migration will be rejected. Could specify any number of overwrite arguments.

    In the future, this command will evolve to running migration files that are automatically generated from the generate command above during schema reconciliation.


    The following commands are also accessible for help developing with Fuego.


    There are a few features not yet available in related libraries for Fuego to run in the way it would like to. We inject these features during NPM's postinstall process so that we could smooth over usage until the related libraries implement them directly. To utilize, please add the following to your package.json within the scripts object:

    postinstall: fuego postinstall

    You should pass in as arguments any package that is exports as ESM. Remix doesn't have a great way of handling this so the post install will convert the package to CJS using esbuild.


    This is the only global command meant to create a new project from scratch. It uses Remix Stacks under the hood allowing you to pass in any existing GitHub stack template. It will also use the input domain as the name for the generated repository and all other name related parameters.

    npm install -g fuegojs@latest
    npx fuego init --domain

    This command takes in the following arguments:

    • --domain [name] - REQUIRED The domain where your app will be hosted. The name will be used for your Github repo and several other naming conventions.
    • --template [name] - The Remix Stack to use for initialization. By default, it will use dvargas92596/fuegojs/tree/main/template, which points to the Remix stack located in the /template directory in this repository.
      • Note: - The template is currently very custom to my apps ("Vargas Arts" branding and such), and I will be working to make it more generic in the coming versions.
