# Address autosuggestion and validation Wrapper for the BPOST's address autosuggest and validate API. - Only for Belgium addresses. - Supports typescript.

Required Node changes

You might need to set up a flag when running your app such as --max-http-header-size 35000 since the incoming headers are way more than default. Node's default 8KB is therefor not enough.(CVE-2018-12121 and CVE-2018-12122).

Installing

// npm
npm i @leventhan/address-validation-and-autosuggestions

// yarn 
yarn add @leventhan/address-validation-and-autosuggestions

Examples

Example for the autosuggestion

const autoSuggestion = new AutoSuggestion()

const streetExample = "Nationalestraat 3";
let inputMock = '';
for(const letter of streetExample) {
    // mocking like user is typing (protip: use lodash debounce in realtime)
    inputMock += letter;

    autoSuggestion.getSuggestions(inputMock).then((response) => {
        console.log(response)
    }).catch((err) => {
        console.log(err)
    })
}
/* Below example responses are minified, therefor please use beautify tools to have a better look. */

/* 
First response on letter N:
{ ... see the full example in the examples folder ...}
*/
/* 
etc... to Nationalestraat 3 we would end up with:
    {"response":{"sequenceNumber":264,"topSuggestions":[{"address":{"latitude":51.210046,"longitude":4.07592,"coordinateSystem":"SPHERICAL","perspectiveCode":"OSM_NETWORK","reliability":10,"detectedLanguage":"nl","province":"Oost-Vlaanderen","isComplete":true,"string":"NATIONALESTRAAT 3  -  9190 STEKENE","searchBarString":"NATIONALESTRAAT 3  -  9190 STEKENE","houseNumber":"3","streetName":"NATIONALESTRAAT","municipalityName":"STEKENE","postalCode":"9190"}},{"address":{"latitude":51.2168045044,"longitude":4.399479866,"coordinateSystem":"SPHERICAL","perspectiveCode":"STREET_LEVEL_ACCESS","reliability":10,"detectedLanguage":"nl","province":"Antwerpen","isComplete":true,"string":"NATIONALESTRAAT 30-32  -  2000 ANTWERPEN","searchBarString":"NATIONALESTRAAT 30-32  -  2000 ANTWERPEN","houseNumber":"30-32","streetName":"NATIONALESTRAAT","municipalityName":"ANTWERPEN","postalCode":"2000"}},{"address":{"latitude":51.217084,"longitude":4.399732,"coordinateSystem":"SPHERICAL","perspectiveCode":"OSM_NETWORK","reliability":10,"detectedLanguage":"nl","province":"Antwerpen","isComplete":true,"string":"NATIONALESTRAAT 31  -  2000 ANTWERPEN","searchBarString":"NATIONALESTRAAT 31  -  2000 ANTWERPEN","houseNumber":"31","streetName":"NATIONALESTRAAT","municipalityName":"ANTWERPEN","postalCode":"2000"}},{"address":{"latitude":51.217012,"longitude":4.399674,"coordinateSystem":"SPHERICAL","perspectiveCode":"OSM_NETWORK","reliability":5,"detectedLanguage":"nl","province":"Antwerpen","isComplete":true,"string":"NATIONALESTRAAT 33  -  2000 ANTWERPEN","searchBarString":"NATIONALESTRAAT 33  -  2000 ANTWERPEN","houseNumber":"33","streetName":"NATIONALESTRAAT","municipalityName":"ANTWERPEN","postalCode":"2000"}},{"address":{"latitude":51.216769,"longitude":4.399489,"coordinateSystem":"SPHERICAL","perspectiveCode":"OSM_NETWORK","reliability":5,"detectedLanguage":"nl","province":"Antwerpen","isComplete":true,"string":"NATIONALESTRAAT 36  -  2000 ANTWERPEN","searchBarString":"NATIONALESTRAAT 36  -  2000 ANTWERPEN","houseNumber":"36","streetName":"NATIONALESTRAAT","municipalityName":"ANTWERPEN","postalCode":"2000"}}]}}

Example for validation

const validationAddress = new Validation();

const mockData = {
    street: "Nationalestraat",
    houseNumber: "30-32",
    bus: "",
    postalCode: 2000,
    city: "Antwerpen"
}
validationAddress.validate(
    mockData.street,
    mockData.houseNumber,
    mockData.bus,
    mockData.postalCode,
    mockData.city
).then((response) => {
    console.log(response)
}).catch((err) => {
    console.log(err)
})
/* Below example responses are minified, therefor please use beautify tools to have a better look. */
/* Example response:
    {"status":"0","message":"Success","address_response":[{"Score":null,"StreetName":"NATIONALESTRAAT","StreetNumber":"30-32","BoxNumber":null,"PostalCode":"2000","MunicipalityName":"ANTWERPEN","CountryName":"BELGIE","Latitude":"51.2168045044","Longitude":"4.399479866","Label":["NATIONALESTRAAT 30-32","2000 ANTWERPEN"]}],"count_add":1,"transaction_id":"0afec0ab-96c6-48e2-81d9-0d7188d9c11f","error_code":[],"error_count":0}
