Upgrade guides for the API client

Upgrade to v6# Found an issue? Edit this page

We entirely rewrote the .NET client but we chose to keep a similar design to make it as easy as possible to upgrade.

There is still a client and an index class but they have been renamed to SearchClient and SearchIndex with similar method names.

This new version is compatible with the same .NET versions as before (from .NET 4.5 to .NET Core 2.2)

Client Instantiation# Found an issue? Edit this page

Replace the instantiation of the client as shown below.

// Before
AlgoliaClient client = new AlgoliaClient("AJ0P3S7DWQ", "••••••••••••••••••••ce1181300d403d21311d5bca9ef1e6fb");
Index index = client.InitIndex("your_index_name");

// After
SearchClient client = new SearchClient("AJ0P3S7DWQ", "••••••••••••••••••••ce1181300d403d21311d5bca9ef1e6fb");
SearchIndex index = client.InitIndex("your_index_name");

Using configuration#

All clients can be instantiated via configuration objects. This is useful to affect the way a client behaves. You can configure :

• DefaultHeaders to set HTTP Headers for every request
• BatchSize to customize the size of batch for save methods
• Hosts to set custom hosts

Example:

SearchConfig config = new SearchConfig("AJ0P3S7DWQ", "••••••••••••••••••••ce1181300d403d21311d5bca9ef1e6fb")
{
  BatchSize = 2000,
  DefaultHeaders = new Dictionary<string, string>
  {
    { "MyCustomerHeaderKey", "MyCustomerHeaderValue" }
  }
};

SearchClient client = new SearchClient(config);

Analytics Instantiation# Found an issue? Edit this page

Similarly, you need to update the way you initialize the Analytics client.

Analytics analytics = new Analytics(client);

// After
AnalyticsClient analytics = new AnalyticsClient("AJ0P3S7DWQ", "••••••••••••••••••••ce1181300d403d21311d5bca9ef1e6fb";

New Methods# Found an issue? Edit this page

Some new methods were added to help implement some commonly used features. These features were always available but required either a deeper understanding or custom code.

• CopySettings: Allows you to copy settings between indices.
• CopySynonyms: Allows you to copy synonyms between indices.
• CopyRules: Allows you to copy rules between indices.
• ReplaceAllObjects: Allows you to add new objects to an index and remove all existing ones, atomically.
• ReplaceAllSynonyms: Allows you to add new synonyms to an index and remove all existing ones, atomically.
• ReplaceAllRules: Allows you to add new rules to an index and remove all existing ones, atomically.
• AccountClient.CopyIndex: Allows you to copy an index between Algolia applications. Very handy when doing client work.
• CustomRequest: Allows you to request the Algolia API with custom parameters, URI, and headers.

Breaking Changes# Found an issue? Edit this page

JObject and types#

The v6 of the client, in contrast to the previous one, is Typed for every method. This implies a breaking change on almost all methods. You can still save and retrieve your records with JObject. However, regarding Settings, Rules, APIkeys, and Synonyms, you will have to convert your JObject to a class.

How to export JObject to new types#

Example with settings :

1
2
3
4
// Your old JObject
JObject oldObject = JObject.Parse("{\"customRanking\":[\"desc(population)\", \"asc(name)\"], \"attributesToIndex\":[\"attr1\", \"attr2\"],\"numericAttributesToIndex\": [\"attr1\", \"attr2\"]}");

IndexSettings settings = oldObject.ToObject<IndexSettings>();

This snippet also works for all other classes in the client as Rules, APIkeys, Synonyms, etc.
