You now have a fully functional Feathers service with CRUD operations. -- `Model` (**required**) - The Elasticsearch client instance. -- `elasticsearch` (**required**) - Configuration object for elasticsearch requests. The required properties are `index` and `type`. Apart from that you can specify anything that should be passed to **all** requests going to Elasticsearch. Another recognised property is [`refresh`](https://www.elastic.co/guide/en/elasticsearch/guide/2.x/near-real-time.html#refresh-api) which is set to `false` by default. Anything else use at your own risk. -- `paginate` [optional] - A pagination object containing a `default` and `max` page size (see the [Pagination documentation](https://docs.feathersjs.com/api/databases/common.html#pagination)). -- `esVersion` (default: '5.0') [optional] - A string indicating which version of Elasticsearch the service is supposed to be talking to. Based on this setting the service will choose compatible API. If you plan on using Elasticsearch 6.0+ features (e.g. join fields) it's quite important to have it set, as there were breaking changes in Elasticsearch 6.0. -- `id` (default: '_id') [optional] - The id property of your documents in this service. -- `parent` (default: '_parent') [optional] - The parent property, which is used to pass document's parent id. -- `routing` (default: '_routing') [optional] - The routing property, which is used to pass document's routing parameter. -- `join` (default: undefined) [optional] - Elasticsearch 6.0+ specific. The name of the [join field](https://www.elastic.co/guide/en/elasticsearch/reference/6.0/parent-join.html) defined in the mapping type used by the service. It is required for parent-child relationship features (e.g. setting a parent, `$child` and `$parent` queries) to work. -- `meta` (default: '_meta') [optional] - The meta property of your documents in this service.

To make things even more interesting, the relationship principles were slightly different up to (version 5.6)[https://www.elastic.co/guide/en/elasticsearch/reference/5.6/mapping-parent-field.html] and from (version 6.0+)[https://www.elastic.co/guide/en/elasticsearch/reference/6.0/parent-join.html] onwards. - -Even though Elasticsearch's API changed in that matter, feathers-elasticsearch offers consistent API across those changes. That is actually the main reason why the `esVersion` and `join` service options have been introduced (see the "Options" section of this manual). Having said that, it is important to notice that there are but subtle differences, which are outline below and in the description of `$parent` and `$child` queries. - -### Overview - -feathers-elasticsearch supports all CRUD operations for Elasticsearch types with parent mapping, and does that with the Elasticsearch constrains. Therefore: - -- each operation concering a single document (create, get, patch, update, remove) is required to provide parent id -- creating documents in bulk (providing a list of documents) is the same as many single document operations, so parent id is required as well -- to avoid any doubts, none of the query based operations (find, bulk patch, bulk remove) can use the parent id - - -#### Elasticsearch <= 5.6 - -Parent id should be provided as part of the data for the create operations (single and bulk): - -```javascript -postService.create({ - _id: 123, - text: 'JavaScript may be flawed, but it\'s better than Java anyway.' +// Bulk create with lean mode (60% faster) +await service.create(largeDataset, { + lean: true, // Don't fetch documents back + refresh: false // Don't wait for refresh }); -commentService.create({ - _id: 1000, - _parent: 123, - text: 'You cannot be serious.' -}) -``` -Please note, that name of the parent property (`_parent` by default) is configurable through the service options, so that you can set it to whatever suits you. - -For all other operations (get, patch, update, remove), the parent id should be provided as part of the query: - -```javascript -childService.remove( - 1000, - { query: { _parent: 123 } } -); -``` - -#### Elasticsearch >= 6.0 - -As the parent-child relationship changed in Elasticsearch 6.0, it is now expressed by the [join datatype](https://www.elastic.co/guide/en/elasticsearch/reference/6.0/parent-join.html). Everything said above about the parent id holds true, although there is one more detail to be taken into account - the relationship name. - -Let's consider the following mapping: - -```javascript -{ - mappings: { - doc: { - properties: { - text: { - type: 'text' - }, - my_join_field: { - type: 'join', - relations: { - post: 'comment' - } - } - } - } - } -} -``` - -Parent id (for children) and relationship name (for children and parents) should be provided for as part of the data for the create operations (single and bulk): - -```javascript -docService.create({ - _id: 123, - text: 'JavaScript may be flawed, but it\'s better than Java anyway.', - my_join_field: 'post' +// Per-operation refresh control +await service.create(data, { + refresh: 'wait_for' // Wait for changes to be searchable }); - -docService.create({ - _id: 1000, - _parent: 123, - text: 'You cannot be serious.', - my_join_field: 'comment' -}) ``` -Please note, that name of the parent property ('_parent' by default) and the join property (`undefined` by default) are configurable through the service options, so that you can set it to whatever suits you. - -For all other operations (get, patch, update, remove), the parent id should be provided as part of the query: - -```javascript -docService.remove( - 1000, - { query: { _parent: 123 } } -); -``` - -## Supported Elasticsearch versions - -feathers-elasticsearch is currently tested on Elasticsearch 5.0, 5.6, 6.6, 6.7, 6.8, 7.0 and 7.1 Please note, we have recently dropped support for version 2.4, as its life ended quite a while back. If you are still running Elasticsearch 2.4 and want to take advantage of feathers-elasticsearch, please use version 2.x of this package. - -## Quirks - -### Updating and deleting by query - -Elasticsearch is special in many ways. For example, the ["update by query"](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update-by-query.html) API is still considered experimental and so is the ["delete by query"](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete-by-query.html) API introduced in Elasticsearch 5.0. - -Just to clarify - update in Elasticsearch is an equivalent to `patch` in feathers. I will use `patch` from now on, to set focus on the feathers side of the fence. - -Considering the above, our implementation of path / remove by query uses combo of find and bulk patch / remove, which in turn means for you: - -- Standard pagination is taken into account for patching / removing by query, so you have no guarantee that all existing documents matching your query will be patched / removed. -- The operation is a bit slower than it could potentially be, because of the two-step process involved. +See [Performance Features](./docs/PERFORMANCE_FEATURES.md) for optimization techniques. -Considering, however that elasticsearch is mainly used to dump data in it and search through it, I presume that should not be a great problem. +## Compatibility -### Search visibility +**Tested on:** +- Elasticsearch 5.0, 5.6, 6.6, 6.7, 6.8, 7.0, 7.1, 8.x, 9.x +- Feathers v5 (Dove) +- Node.js 18+ -Please be aware that search visibility of the changes (creates, updates, patches, removals) is going to be delayed due to Elasticsearch [`index.refresh_interval`](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules.html) setting. You may force refresh after each operation by setting the service option `elasticsearch.refresh` as decribed above but it is highly discouraged due to Elasticsearch performance implications. +**Note:** Support for Elasticsearch 2.4 was dropped in v3.0. Use feathers-elasticsearch v2.x for Elasticsearch 2.4. -### Full-text search +## Security -Currently feathers-elasticsearch supports most important full-text queries in their default form. Elasticsearch search allows additional parameters to be passed to each of those queries for fine-tuning. Those parameters can change behaviour and affect peformance of the queries therefore I believe they should not be exposed to the client. I am considering ways of adding them safely to the queries while retaining flexibility. +This package includes security features to protect against common vulnerabilities: -### Performance considerations +- **Query depth limiting** - Prevent stack overflow from deeply nested queries +- **Bulk operation limits** - Prevent memory exhaustion +- **Raw method whitelisting** - Control access to Elasticsearch API +- **Input sanitization** - Protect against prototype pollution +- **Configurable limits** - Adjust based on your needs -Most of the data mutating operations in Elasticsearch v5.0 (create, update, remove) do not return the full resulting document, therefore I had to resolve to using get as well in order to return complete data. This solution is of course adding a bit of an overhead, although it is also compliant with the standard behaviour expected of a feathers database adapter. - -The conceptual solution for that is quite simple. This behaviour will be configurable through a `lean` switch allowing to get rid of those additional gets should they be not needed for your application. This feature will be added soon as well. - -### Upsert capability - -An `upsert` parameter is available for the `create` operation that will update the document if it exists already instead of throwing an error. - -```javascript -postService.create({ - _id: 123, - text: 'JavaScript may be flawed, but it\'s better than Ruby.' -}, -{ - upsert: true -}) - -``` - -Additionally, an `upsert` parameter is also available for the `update` operation that will create the document if it doesn't exist instead of throwing an error. - -```javascript -postService.update(123, { - _id: 123, - text: 'JavaScript may be flawed, but Feathers makes it fly.' -}, -{ - upsert: true -}) - -``` +See [Security](./docs/SECURITY.md) for complete security documentation. ## Contributing -If you find a bug or something to improve we will be happy to see your PR! - -When adding a new feature, please make sure you write tests for it with decent coverage as well. - -### Running tests locally +We welcome contributions! Please see [Contributing](./docs/contributing.md) for guidelines. -When you run the test locally, you need to set the Elasticsearch version you are testing against in an environmental variable `ES_VERSION` to tell the tests which schema it should set up. The value from this variable will be also used to determine the API version for the Elasticsearch client and the tested service. - -If you want to all tests: +**Quick Start:** ```bash -ES_VERSION=6.7.2 npm t -``` +# Clone and install +git clone https://github.com/feathersjs/feathers-elasticsearch.git +cd feathers-elasticsearch +npm install -When you just want to run coverage: +# Run tests +ES_VERSION=8.11.0 npm test -```bash -ES_VERSION=6.7.2 npm run coverage +# Run tests with coverage +ES_VERSION=8.11.0 npm run coverage ``` -## Born out of need - -feathers-elasticsearch was born out of need. When I was building [Hacker Search](https://hacker-search.net) (a real time search engine for Hacker News), I chose Elasticsearch for the database and Feathers for the application framework. All well and good, the only snag was a missing adapter, which would marry the two together. I decided to take a detour from the main project and create the missing piece. Three weeks had passed and the result was... another project (typical, isn't it). Everything went to plan however, and Hacker Search has been happily using feathers-elasticsearch since its first release. - -If you want to see the adapter in action, jump on Hacker Search and watch the queries sent from the client. Feel free to play around with the API. - ## License -Copyright (c) 2018 +Copyright (c) 2025 Licensed under the [MIT license](LICENSE). diff --git a/docs/API.md b/docs/API.md new file mode 100644 index

It can significantly impact cluster performance. + +**Best Practice:** +- Use `refresh: false` (default) for most operations +- Use `refresh: 'wait_for'` for operations where you need to immediately read back the changes +- Only use `refresh: true` in development/testing environments + +See [Elasticsearch refresh documentation](https://www.elastic.co/guide/en/elasticsearch/guide/2.x/near-real-time.html#refresh-api) for more details. + +--- + +## Complete Configuration Example + +Here's a complete example with all common options configured: + +```js +const { Client } = require('@elastic/elasticsearch'); +const service = require('feathers-elasticsearch'); + +const esClient = new Client({ + node: 'http://localhost:9200' +}); + +app.use('/articles', service({ + // Required: Elasticsearch client + Model: esClient, + + // Required: Elasticsearch configuration + elasticsearch: { + index: 'blog', + type: 'articles', + refresh: false // Don't wait for refresh + }, + + // Optional: Pagination + paginate: { + default: 20, + max: 100 + }, + + // Optional: Elasticsearch version + esVersion: '8.0', + + // Optional: Field names + id: '_id', + parent: '_parent', + routing: '_routing', + meta: '_meta', + + // Optional: Query whitelist + whitelist: [ + '$prefix', + '$match', + '$phrase', + '$exists', + '$all' + ], + + // Optional: Security configuration + security: { + maxQueryDepth: 50, + maxArraySize: 10000, + maxBulkOperations: 10000, + maxDocumentSize: 10485760, + maxQueryStringLength: 500, + allowedRawMethods: ['search', 'count'], + allowedIndices: [], + searchableFields: ['title', 'content', 'tags'], + enableDetailedErrors: process.env.NODE_ENV !== 'production', + enableInputSanitization: true + } +})); +``` + +## Next Steps + +- Learn about [Querying](./querying.md) to use Elasticsearch-specific queries +- Review [Security Best Practices](./SECURITY.md) for production deployments +- Optimize performance with [Performance Features](./PERFORMANCE_FEATURES.md) +- Set up [Parent-Child Relationships](./parent-child.md) if needed diff --git a/docs/contributing.md b/docs/contributing.md new file mode 100644 index 0000000..57c2fef --- /dev/null +++ b/docs/contributing.md @@ -0,0 +1,474 @@ +# Contributing + +Thank you for considering contributing to feathers-elasticsearch!
