jlc-dev-serve v0.9.6

jlc-dev-serve

A simple and efficient HTTP/S server for serving static files, meant to be used during development (with sane defaults).

In my other HTTP-server project I wanted to include "the whole kitchen sink" and hence I never really had anything stable to release.

In this project I'll try keep it simple and only include the most needed features we need for local development (e.g. no minifying of files).

Features

• HTTPS server with automatic certificates for development (devcert).
• Directory watcher (chokidar) with LiveReload support.
• Etag support (utilizes browser cache when possible).
• Compression support (gzip and Brotli).
• Directory listing (can be turned off).
• Bootstrapping index.js files.
• MIME types support through mime.
• Very small amount of code written so anyone can understand it!

Usage

npx jlc-dev-serve

(with npx it doesn't have to be installed first)

Will serve the files in the current directory.

Note

It seems that when using npx you'll get the warning The `punycode` module is deprecated. I have a script to fix the dependency which cause this warning, but that script is only executed on the installation of my package.

Hence to get rid of that warning just install my package globally like this:

npm install -g jlc-dev-serve

Configuration

It can be configured by setting environment variables. E.g. like this:

HTTP=1 HOST=0.0.0.0 PORT=1337 npx jlc-dev-serve

Environment variables (all are optional): | Variable | Description | | --- | --- | | HTTP | Set (to 1 or true) to use HTTP instead of HTTPS. | | CERT | The certificate (PEM format) to use with the HTTPS server or a path to it. | | KEY | The private key (PEM format) to use with the HTTPS server or a path to it. | | PASS | The passphrase (if KEY needs one). | | PORT | The port to use (defaults to 8080 for HTTP and 4433 for HTTPS). | | HOST | Defaults to localhost. Use 0.0.0.0 to accept any IPv4 connection or :: to accept any IPv6 and IPv4 connection (on most systems). | | PUBLIC | A shortcut to setting the host to ::. | | PREFIX | Add a prefix which URLs must begin with to access the served files. | | REDIRECT | Redirect any HTTP connections to this port to the HTTPS server. | | COMPRESSION | Whether to support "Brotli" and "gzip" compression. | | IGNORE_INDEX | Ignore any index.html file when browsing path/. | | JS_BOOTSTRAP | Can be set to "bootstrap" index.js and index.mjs files by using "virtual HTML indexes" which just runs them. It can also define a list of scripts to execute before running them. Documentation here. | | NO_DIRECTORY_LISTING | When browsing path/ do NOT list its contents. | | NO_LIVE_RELOAD | Set to NOT start the LiveReload server. |

Documentation of JS_BOOTSTRAP

The JS_BOOTSTRAP environment variable can be set to "bootstrap" index.js and index.mjs files by using "virtual HTML indexes" which just runs them. It can also define a list of scripts to execute before running them.

Setting JS_BOOTSTRAP=1 or to true will enable this feature and depending on their .js or .mjs extension they will run as normal scripts or scripts with type="module" set. But setting it to JS_BOOTSTRAP=module will override this and run them all as modules.

You can even define a static list of scripts to run before them and also define whether each of these should run as normal scripts or modules as well.

E.g. like this:

JS_BOOTSTRAP=module|http://domain.com/script_x.js|/and_my_own_script_to_run_before_any_indexjs.js

Here the first script is loaded as a module while the second one isn't, because it wasn't preceded by module|.

Changing it to:

JS_BOOTSTRAP=module|http://domain.com/script_x.js|/and_my_own_script_to_run_before_any_indexjs.js|module

Will function the same as JS_BOOTSTRAP=module does and load your index.js as modules.

The End

That's it, there's really not much more to it!
