Hastur

A small node http server for rendering of react components (must be transpiled if using experimental features not found in node.js)

Requirements

Node.js > 8.x

Installation & start

npm install git://github.com/Frojd/Hastur.git
node hastur.js

Use docker image: frojd/hastur

Server configurations

As env variables:

    HASTUR_PATH=/path/to/components/
    HASTUR_PORT=3000
    HASTUR_HOST=0.0.0.0
    HASTUR_DEBUG=true
    HASTUR_SENTRY=https://xxxx:yyyy@sentry.io/1234
    HASTUR_JSON_SNAKE_TO_CAMEL=true
    HASTUR_STRIP_DOT_PREFIX=true

or as parameters:

node app.js --port 3000 --host 0.0.0.0 --path /path/to/components/ --sentry https://xxxx:yyyy@sentry.io/1234 --debug --toCamelFromSnake --stripDotPrefix

How to use

When started without any parameters, Hastur will accept application/json http POST request at http://localhost:3000 with this body:

{
  "componentName": "MyComponent",
  "props": {
    "title": "my props title",
    "anyProp": "another prop"
  },
  "static": false,
  "context": {
    "location": "https://mysite.com",
    "otherContext": "foo"
  }
}

The above request will try to do a require(componentName) and render it with the passed along props. If HASTUR_PATH is set, it will be prepended to the componentName.

static (optional, default: false):

If true, Hastur will return html without react bindings

context (optional, default: undefined)

If you need to pass along things that otherwise would not be included on the server side (such as request-info) you can pass it along in the context attribute:

{
  "location": "https://somesite.com/foo"
}

You can access it in your components via the SSRContext object, allowing you to do stuff like:

const currentURL = SSRContext.location ? SSRContext.location : window.location;
if (currentURL.search(/foo/)) {
  console.log('The requested URL contains "foo"');
}
