TravelTime API SDK for node js with TypeScript
npm install traveltime-api

Travel Time Node.js SDK helps users find locations by journey time rather than using ‘as the crow flies’ distance. Time-based searching gives users more opportunities for personalisation and delivers a more relevant search.
```
npm i traveltime-api
This package comes with TypeScript support.
Before starting, the package needs to be configured with your account's application ID and Key, which can be found in the TravelTime Developer Portal Dashboard.
To create an instance - you will need to create new TravelTimeClient class object with credentials you got from dashboard.
`typescript
import { TravelTimeClient } from 'traveltime-api';
const travelTimeClient = new TravelTimeClient({
apiKey: 'YOUR_APP_KEY',
applicationId: 'YOUR_APP_ID',
});
`
#### Advanced Options
You can apply additional optional parameters to client constructor’s second argument parameters object:baseURL
- [string] - you can change base URL of client. Default value is https://api.traveltimeapp.com/v4.axiosInstance
- [object] - if needed, you can pass your own axios instance.rateLimitSettings
- [object] - in order to keep within limits we suggest enabling this feature to reduce risk of receiving HTTP 429 Too Many Requests errors. When using rate limiter if the response status is 429 we will retry your request up to 3 times. This object accepts these arguments:enabled
- [boolean] - pass true to enable rate limiter on this SDK instance. Default is set to false.hitsPerMinute
- [number] - pass number that your plan supports. You can find what HPM your plan supports here. If you are on custom plan and not sure of your limits feel free to contact us. Default value is 60.retryCount
- [number] - Determines how many times request should be repeated when API returns status 429. Default is 3.timeBetweenRetries
- [number] - Determines how often retry should happen. Time units - milliseconds. Default is 1000.
If you need to change any of these parameters you can call setter methods: travelTimeClient.setBaseURL, travelTimeClient.setRateLimitSettings.
---
Now you'll be able to call all TravelTime API endpoints from travelTimeClient instance.
Every instance function returns Object with type of Promise.
#### Batch Processing
Most endpoints are available with batch processing:
`typescript
const departure_search: TimeMapRequestDepartureSearch = {
id: 'public transport from Trafalgar Square',
departure_time: new Date().toISOString(),
travel_time: 900,
coords: { lat: 51.507609, lng: -0.128315 },
transportation: { type: 'public_transport' },
properties: ['is_only_walking'],
};
const searches = Array(100).fill({ departure_searches: [departure_search] });
travelTimeClient.timeMapBatch(searches, 'application/geo+json')
.then((data) => {
data.forEach((search) => console.log(search));
})
.catch((e) => console.error(e));
`
Batch processing endpoints always return the same amount of responses and does not crash on an invalid request. It is up to the user to inspect whether the response was a success. isBatchError utility function is provided to facilitate inspecting batch responses.
`typescript
const response: BatchResponse
if (isBatchError(response)) {
response.error; // handle error
} else {
response.body; // handle success
}
`
Body attributes:
* departure_searches: Searches based on departure times. Leave departure location at no earlier than given time. You can define a maximum of 10 searches.
* arrival_searches: Searches based on arrival times. Arrive at destination location at no later than given time. You can define a maximum of 10 searches.
* unions: Define unions of shapes that are results of previously defined searches.
* intersections: Define intersections of shapes that are results of previously defined searches.
Function accepts object that matches API json spec.

This utility function leverages travelTimeClient.timeFilter (as described in the previous section) to efficiently construct Many-to-Many matrices in batches.
`ts`
const matrix = await travelTimeClient.manyToManyMatrix({
coordsFrom: [
{ lat: 51.5055, lng: -0.0754 },
{ lat: 51.5171, lng: -0.1062 },

],
transportation: { type: 'driving' },
properties: ['travel_time', 'distance'],
travelTime: 1800,
leaveTime: new Date().toISOString(),
});
The response will be in the following format:
`json`
{
"travelTimes":[
[0,1637,-1,1516,-1],
[1689,0,956,991,-1],
[-1,815,0,1193,1178],

[1550,1072,1522,0,1748],
[-1,1702,1414,1556,0]
],
"errors":[]
}
The travelTimes and distances arrays are structured so that you can access specific values using response.travelTimes[indexOfLocationFrom][indexOfLocationTo]. Unreachable destinations are represented by -1. If there was an error while fetching the response, those entries will be marked as null. You can view all errors in the response.errors field.

#### Transportation Details
When picking transportation mode for proto requests take note that some of the transportation modes
support extra configuration parameters.
##### Public Transport
`typescript`
transportation: {
mode: 'pt',
details: {
walkingTimeToStation: 1800
}
},
pt transportion mode and allows to set these parameters:walking_time_to_station
* - limits the possible duration of walking paths.
This limit is of low precedence and will not override the global travel time limit
Optional. Must be <= 1800.
##### Driving and Public Transport
`typescript`
transportation: {
mode: 'driving+pt',
details: {
walkingTimeToStation: 1800,
drivingTimeToStation: 1800,
parkingTime: 900
}
},
driving+pt transportion mode and allows to set these parameters:walking_time_to_station
* - limits the possible duration of walking paths.driving_time_to_station
This limit is of low precedence and will not override the global travel time limit.
Optional. Must be <= 1800.
* - limits the possible duration of driving paths.parking_time
This limit is of low precedence and will not override the global travel time limit
Optional. Must be <= 1800.
* - constant penalty to apply to simulate the difficulty of finding a parking spot.
Optional. Cannot be greater than the global travel time limit.
Function accepts object that matches API json spec.
Body attributes:
