**Motivations:** - Ensure all application directories have systemd services enabled at boot - Complete service installation for api-relay, filigrane-api, and clamav-api - Fix dependencies and import issues preventing clamav-api from starting **Root causes:** - Three services (api-relay, filigrane-api, clamav-api) had service files but were not installed in systemd - api-clamav had incorrect node-clamav version (0.12.1) that doesn't exist - api-clamav dependencies were not installed (node_modules missing) - ES module import syntax incompatible with CommonJS node-clamav package **Correctifs:** - Installed api-relay.service, filigrane-api.service, and clamav-api.service in /etc/systemd/system/ - Enabled all three services for automatic startup at boot - Updated api-clamav/package.json: changed node-clamav version from ^0.12.1 to ^1.0.11 - Installed npm dependencies for api-clamav - Fixed ES module import in api-clamav/src/routes/scan.js to use CommonJS-compatible syntax **Evolutions:** - All 7 application services now have systemd services enabled at boot - Complete service coverage: anchorage-api, faucet-api, signet-dashboard, userwallet, api-relay, filigrane-api, clamav-api - All services verified active and listening on their respective ports **Pages affectées:** - api-clamav/package.json - api-clamav/src/routes/scan.js - api-clamav/node_modules/ (new) - api-clamav/package-lock.json (new) - /etc/systemd/system/api-relay.service (new) - /etc/systemd/system/filigrane-api.service (new) - /etc/systemd/system/clamav-api.service (new)
negotiator
An HTTP content negotiator for Node.js
Installation
$ npm install negotiator
API
var Negotiator = require('negotiator')
Accept Negotiation
availableMediaTypes = ['text/html', 'text/plain', 'application/json']
// The negotiator constructor receives a request object
negotiator = new Negotiator(request)
// Let's say Accept header is 'text/html, application/*;q=0.2, image/jpeg;q=0.8'
negotiator.mediaTypes()
// -> ['text/html', 'image/jpeg', 'application/*']
negotiator.mediaTypes(availableMediaTypes)
// -> ['text/html', 'application/json']
negotiator.mediaType(availableMediaTypes)
// -> 'text/html'
You can check a working example at examples/accept.js.

Accept-Language Negotiation
negotiator = new Negotiator(request)
availableLanguages = ['en', 'es', 'fr']
// Let's say Accept-Language header is 'en;q=0.8, es, pt'
negotiator.languages()
// -> ['es', 'pt', 'en']
negotiator.languages(availableLanguages)
// -> ['es', 'en']
language = negotiator.language(availableLanguages)

Accept-Charset Negotiation
availableCharsets = ['utf-8', 'iso-8859-1', 'iso-8859-5']
negotiator = new Negotiator(request)
// Let's say Accept-Charset header is 'utf-8, iso-8859-1;q=0.8, utf-7;q=0.2'
negotiator.charsets()
// -> ['utf-8', 'iso-8859-1', 'utf-7']
negotiator.charsets(availableCharsets)
