This microservice is a little express server that takes an HTTP POST request.
Node.js and a dream
-
To begin, clone the repository into a new folder.
-
Run
npm installinside that folder.
To change the port the server runs on, edit the corresponding line in the config.json file.
To start the server, run npm start.
By default, all requests are to be made to http:/127.0.0.1:3000/ as HTTP POSTs.
Send your data in the request body and include application/json as the Content-Type header.
Request bodies are expected to follow the following format:
{
tile_costs: [[Number, Number]], // Initial, Monthly
tile_layout: [[Number, ...]], // Tile ID
selection_topleft: [Number, Number] || undefined, // x, y; Optional
selection_bottomright: [Number, Number] || undefined, // x, y; Optional
}If the server understood your request and found no validation errors, an HTTP response will be returned:
{
price_initial: Number,
price_monthly: Number,
tiles: [
{
quantity: Number,
initial: Number,
monthly: Number
},
],
}The server will repeat json contained in requests and responses to stdout.
If there is invalid syntax in a request, the server will send a message to stderr with details as to any attempted wrongdoing and send back an HTTP 400 error in response.
Sample request body:
{
tile_costs: [
[25, 10],
[10, 0],
[5, 5],
],
tile_layout: [
[0, 1, 0],
[0, 0, 0],
[2, 2, 2],
],
selection_topleft: [0, 0],
selection_bottomright: [1, 1],
}Sample response:
{
price_initial: 85,
price_monthly: 30,
tiles: [
{ quantity: 3, initial: 75, monthly: 30 },
{ quantity: 1, initial: 10, monthly: 0 },
],
}Example programmatic request / response code:
fetch("http://127.0.0.1:3000/", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify(/* Your Request Here... */),
})
.then((res) => res.json())
.then((data) => {
// Handle data...
})
.catch((err) => {
console.log(`Fetch Error: ${err}`);
});
