MeiliSearch v0.23.0 introduces two changes:

• new valid formats to push data files, additionally to the JSON format: CSV and NDJSON formats.
• it enforces the Content-type header for every route requiring a payload (POST and PUT routes)

---

Here are the expected changes to completely close the issue:

• Currently, the SDKs always send Content-Type: application/json to every request. Only the POST and PUT requests should send the Content-Type: application/json and not the DELETE and GET ones.

• Add the following methods and 🔥 the associated tests 🔥 to ADD the documents. Depending on the format type (csv or ndjson) the SDK should send Content-Type: application/x-dnjson or Content-Type: text/csv)

  • addDocumentsJson(string docs, string primaryKey)
  • addDocumentsCsv(string docs, string primaryKey)
  • addDocumentsCsvInBatches(string docs, int batchSize, string primaryKey)
  • addDocumentsNdjson(string docs, string primaryKey)
  • addDocumentsNdjsonInBatches(string docs, int batchSize, string primaryKey)

• Add the following methods and 🔥 the associated tests 🔥 to UPDATE the documents. Depending on the format type (csv or ndjson) the SDK should send Content-Type: application/x-dnjson or Content-Type: text/csv)

  • updateDocumentsJson(string docs, string primaryKey)
  • updateDocumentsCsv(string docs, string primaryKey)
  • updateDocumentsCsvInBatches(string docs, int batchSize, string primaryKey)
  • updateDocumentsNdjson(string docs, string primaryKey)
  • updateDocumentsNdjsonInBatches(string docs, int batchSize, string primaryKey)

docs are the documents sent as String
primaryKey is the primary key of the index
batchSize is the size of the batch. Example: you can send 2000 documents in raw String in docs and ask for a batchSize of 1000, so your documents will be sent to MeiliSearch in two batches.
