📣 We strongly recommend doing multiple PRs to solve all the points of this issue

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.

Thanks for your interest in this project :)

FYI, we prefer not assigning people to our issues because sometimes people ask to be assigned and never come back, which discourages the volunteer contributors to open a PR to fix this issue. We will accept and merge the first PR that fixes correctly and well implements the issue following our contributing guidelines.

We are looking forward to reviewing your PR 🙂
