instead of `ON MATCH SET`) 34 | 35 | ## Versioning Strategy 36 | 37 | Starting with v4.0.0, this library's major version will match the Neo4jClient major version it targets: 38 | - Neo4jClient.Extension 4.x → Neo4jClient 4.x 39 | - Neo4jClient.Extension 5.x → Neo4jClient 5.x (future) 40 | 41 | This makes it clear which version of Neo4jClient is compatible. 42 | 43 | ## [1.0.2] - 2024-08-26 44 | 45 | ### Changed 46 | - Made `UseProperties` method public instead of internal for better extensibility 47 | 48 | ## [1.0.1] - Prior Release 49 | 50 | ### Fixed 51 | - Fixed `CreateRelationship` not honoring relationship identifier 52 | - Fixed "An item with the same key has already been added" exception 53 | - Fixed bad merge affecting `GetFormattedCypher` 54 | 55 | ### Changed 56 | - Reference attributes by project instead of package 57 | 58 | ## [1.0.0] - Initial Release 59 | 60 | ### Added 61 | - Fluent configuration API for entity metadata 62 | - Extension methods for creating, matching, and merging entities 63 | - Extension methods for relationship operations 64 | - Attribute-based configuration support 65 | - Strongly-typed relationship modeling 66 | - Support for ON CREATE SET and ON MATCH SET in MERGE operations 67 | - Automatic property name casing and JSON serialization 68 | - Comprehensive unit and integration test suite 69 | 70 | ### Features 71 | - `CreateEntity` - Create nodes from objects 72 | - `MergeEntity` - Merge nodes with ON CREATE/ON MATCH 73 | - `MatchEntity` - Match nodes by properties 74 | - `CreateRelationship` - Create typed relationships 75 | - `MergeRelationship` - Merge relationships 76 | - `MatchRelationship` - Match relationships 77 | 78 | --- 79 | 80 | ## Version Guidelines 81 | 82 | This project uses

GitHub Actions will: 173 | - Build and test the code 174 | - Create NuGet packages 175 | - Publish to NuGet.org 176 | - Create a GitHub release 177 | 178 | ## Questions? 179 | 180 | Feel free to open an issue for questions or discussions about contributing. 181 | 182 | ## License 183 | 184 | By contributing, you agree that your contributions will be licensed under the same license as the project (see LICENSE file). 185 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # Neo4jClient.Extension 2 | 3 | [![NuGet Version](https://img.shields.io/nuget/v/Neo4jClient.Extension.svg)](https://www.nuget.org/packages/Neo4jClient.Extension/) 4 | [![Build Status](https://img.shields.io/github/actions/workflow/status/simonpinn/Neo4jClient.Extension/ci.yml?branch=master)](https://github.com/simonpinn/Neo4jClient.Extension/actions) 5 | [![License](https://img.shields.io/github/license/simonpinn/Neo4jClient.Extension.svg)](LICENSE) 6 | 7 | A fluent API extension for [Neo4jClient](https://github.com/Readify/Neo4jClient) that simplifies building Cypher queries using strongly-typed C# objects. 8 | 9 | ## Features 10 | 11 | - **Type-Safe Query Building** - Create, match, and merge nodes and relationships using objects instead of writing Cypher strings 12 | - **Fluent Configuration** - Configure entity metadata without cluttering domain models with attributes 13 | - **Relationship Modeling** - Strongly-typed relationships with properties 14 | - **IntelliSense Support** - Full IDE autocomplete for improved productivity 15 | - **Reduced Errors** - Compile-time checking prevents property name typos and refactoring issues 16 | 17 | ## Key Extension Methods 18 | 19 | - `CreateEntity` - Create nodes from objects 20 | - `MergeEntity` - Merge nodes with ON CREATE/ON MATCH support 21 | - `MatchEntity` - Match nodes by properties 22 | - `CreateRelationship` - Create typed relationships 23 | - `MergeRelationship` - Merge relationships 24 | - `MatchRelationship` - Match relationships 25 | 26 | ## Quick Start 27 | 28 | ### Installation 29 | 30 | ```bash 31 | # Install Neo4jClient 32 | dotnet add package Neo4jClient 33 | 34 | # Install Neo4jClient.Extension 35 | dotnet add package Neo4jClient.Extension 36 | ``` 37 | 38 | ### Setup 39 | 40 | ```csharp 41 | using Neo4jClient; 42 | using Neo4jClient.Extension.Cypher; 43 | 44 | // Connect to Neo4j 45 | var client = new BoltGraphClient(new Uri("bolt://localhost:7687"), "neo4j", "password"); 46 | await client.ConnectAsync(); 47 | 48 | // Configure your entities (do this once at startup) 49 | FluentConfig.Config() 50 | .With() 51 | .Match(x => x.Id) 52 | .Merge(x => x.Id) 53 | .MergeOnCreate(p => p.DateCreated) 54 | .Set(); 55 | ``` 56 | 57 | ## Fluent Configuration 58 | 59 | Configure entity metadata once at application startup without decorating your domain models: 60 | 61 | ```csharp 62 | FluentConfig.Config() 63 | .With("SecretAgent") 64 | .Match(x => x.Id) 65 | .Merge(x => x.Id) 66 | .MergeOnCreate(p => p.DateCreated) 67 | .MergeOnMatchOrCreate(p => p.Name) 68 | .MergeOnMatchOrCreate(p => p.Title) 69 | .Set(); 70 | ``` 71 | 72 | Configure relationships with properties: 73 | 74 | ```csharp 75 | FluentConfig.Config() 76 | .With() 77 | .MergeOnMatchOrCreate(hr => hr.DateEffective) 78 | .Set(); 79 | ``` 80 | 81 | ## Usage Examples 82 | 83 | ### Create a Node 84 | 85 | ```csharp 86 | var person = new Person { Id = 1, Name = "John Doe" }; 87 | await client.Cypher 88 | .CreateEntity(person, "p") 89 | .ExecuteWithoutResultsAsync(); 90 | ``` 91 | 92 | ### Create Nodes with Relationships 93 | 94 | ```csharp 95 | var person = new Person { Id = 1, Name = "John Doe" }; 96 | var address = new Address { Street = "123 Main St", City = "Austin" }; 97 | 98 | await client.Cypher 99 | .CreateEntity(person, "p") 100 | .CreateEntity(address, "a") 101 | .CreateRelationship(new HomeAddressRelationship("p", "a")) 102 | .ExecuteWithoutResultsAsync(); 103 | ``` 104 | 105 | ### Merge Nodes 106 | 107 | ```csharp 108 | var person = new Person { Id = 1, Name = "John Doe", DateCreated = DateTime.UtcNow }; 109 | 110 | await client.Cypher 111 | .MergeEntity(person) // Uses configured Merge properties 112 | .MergeEntity(person.HomeAddress) 113 | .MergeRelationship(new HomeAddressRelationship("person", "homeAddress")) 114 | .ExecuteWithoutResultsAsync(); 115 | ``` 116 | 117 | ## Alternative: Attribute Configuration 118 | 119 | For those who prefer attributes, you can decorate your models directly: 120 | 121 | ```csharp 122 | [CypherLabel(Name = "Person")] 123 | public class Person 124 | { 125 | [CypherMerge] 126 | public Guid Id { get; set; } 127 | 128 | [CypherMergeOnCreate] 129 | public string Name { get; set; } 130 | 131 | [CypherMergeOnMatchOrCreate] 132 | public bool IsActive { get; set; } 133 | } 134 | ``` 135 | 136 | **Available Attributes:** 137 | - `CypherLabel` - Custom node label (defaults to class name) 138 | - `CypherMatch` - Used in MATCH clauses 139 | - `CypherMerge` - Used in MERGE clauses 140 | - `CypherMergeOnCreate` - Set only when creating (ON CREATE SET) 141 | - `CypherMergeOnMatch` - Set only when matching (ON MATCH SET) 142 | 143 | > **Note:** Fluent configuration is recommended to keep domain models infrastructure-free. 144 | 145 | ## Relationship Modeling 146 | 147 | Define strongly-typed relationships by inheriting from `BaseRelationship`: 148 | 149 | ```csharp 150 | [CypherLabel(Name = "HOME_ADDRESS")] 151 | public class HomeAddressRelationship : BaseRelationship 152 | { 153 | public HomeAddressRelationship(string fromKey, string toKey) 154 | : base(fromKey, toKey) { } 155 | 156 | public DateTime DateEffective { get; set; } 157 | } 158 | ``` 159 | 160 | ## Development 161 | 162 | ### Building 163 | 164 | ```bash 165 | dotnet build Neo4jClient.Extension.sln 166 | ``` 167 | 168 | ### Running Tests 169 | 170 | **Unit Tests:** 171 | ```bash 172 | dotnet test test/Neo4jClient.Extension.UnitTest/ 173 | ``` 174 | 175 | **Integration Tests** (requires Neo4j): 176 | ```bash 177 | # Automated setup (recommended) 178 | ./run-tests-with-neo4j.sh # Linux/macOS 179 | run-tests-with-neo4j.bat # Windows 180 | 181 | # Manual setup 182 | docker compose up -d neo4j 183 | dotnet test --filter Integration 184 | docker compose down 185 | ``` 186 | 187 | ### Packaging 188 | 189 | ```bash 190 | powershell -f build.ps1 -packageVersion 1.0.0 191 | ``` 192 | 193 | Output: `./_output/` directory 194 | 195 | ## Documentation 196 | 197 | - [CLAUDE.md](CLAUDE.md) - Comprehensive architecture documentation 198 | - [DOCKER-TESTING.md](DOCKER-TESTING.md) - Docker setup for integration tests 199 | - [Unit Tests](test/Neo4jClient.Extension.UnitTest/) - Usage examples 200 | 201 | ## Requirements 202 | 203 | - .NET 9.0 or later 204 | - Neo4jClient 4.0.0+ 205 | - Neo4j 5.x (for integration tests) 206 | 207 | ## Contributing 208 | 209 | Contributions are welcome!

CI Workflow (`.github/workflows/ci.yml`) 61 | 62 | **Triggers:** 63 | - Push to `master`, `develop`, or `feature/**` branches 64 | - Pull requests to `master` or `develop` 65 | 66 | **What it does:** 67 | - Builds the solution 68 | - Runs unit tests 69 | - Starts Neo4j container and runs integration tests 70 | - Creates NuGet packages (on push only) 71 | - Uploads artifacts 72 | 73 | **No secrets required** - This workflow runs on all branches and PRs. 74 | 75 | ### 2. Release Workflow (`.github/workflows/release.yml`) 76 | 77 | **Triggers:** 78 | - Push of version tags (e.g., `v1.2.3`) 79 | 80 | **What it does:** 81 | - Builds and tests the solution 82 | - Creates NuGet packages with version from tag 83 | - Publishes to NuGet.org 84 | - Creates GitHub release with release notes 85 | - Uploads packages to GitHub release 86 | 87 | **Required secret:** `NUGET_API_KEY` 88 | 89 | ## Creating a Release 90 | 91 | To publish a new version to NuGet.org: 92 | 93 | 1. **Ensure all changes are merged to master** 94 | ```bash 95 | git checkout master 96 | git pull origin master 97 | ``` 98 | 99 | 2. **Create and push a version tag** 100 | ```bash 101 | # GitVersion will automatically determine the version 102 | # But you can override by creating a specific tag: 103 | git tag v1.2.3 104 | git push origin v1.2.3 105 | ``` 106 | 107 | 3. **GitHub Actions will automatically:** 108 | - Build and test the code 109 | - Create NuGet packages 110 | - Publish to NuGet.org (using `NUGET_API_KEY`) 111 | - Create a GitHub release 112 | - Attach packages to the release 113 | 114 | 4. **Monitor the release** 115 | - Go to **Actions** tab to watch the workflow 116 | - Check **Releases** tab for the published release 117 | - Verify on [NuGet.org](https://www.nuget.org/packages/Neo4jClient.Extension/) 118 | 119 | ## Branch Protection Rules (Recommended) 120 | 121 | To ensure code quality, configure branch protection: 122 | 123 | 1. Go to **Settings** → **Branches** 124 | 2. Click **Add rule** 125 | 3. Branch name pattern: `master` 126 | 4. Enable: 127 | - ☑ Require a pull request before merging 128 | - ☑ Require status checks to pass before merging 129 | - Select: `build-and-test` (from CI workflow) 130 | - ☑ Require branches to be up to date before merging 131 | - ☑ Include administrators (optional but recommended) 132 | 5. Click **Create** 133 | 134 | Repeat for `develop` branch. 135 | 136 | ## Environment Protection Rules (Optional) 137 | 138 | For additional security on releases: 139 | 140 | 1. Go to **Settings** → **Environments** 141 | 2. Click **New environment** 142 | 3. Name: `production` 143 | 4. Configure: 144 | - **Required reviewers**: Add yourself or trusted maintainers 145 | - **Wait timer**: Optional delay before deployment 146 | 5. Update `release.yml` to use the environment: 147 | ```yaml 148 | jobs: 149 | release: 150 | environment: production 151 | ``` 152 | 153 | ## Status Badge 154 | 155 | Add this badge to your README to show build status: 156 | 157 | ```markdown 158 | [![Build Status](https://img.shields.io/github/actions/workflow/status/simonpinn/Neo4jClient.Extension/ci.yml?branch=master)](https://github.com/simonpinn/Neo4jClient.Extension/actions) 159 | ``` 160 | 161 | ## Troubleshooting 162 | 163 | ### Release workflow fails with "401 Unauthorized" 164 | 165 | - Check that `NUGET_API_KEY` secret is set correctly 166 | - Verify the API key hasn't expired on NuGet.org 167 | - Ensure the API key has push permissions for the package 168 | 169 | ### Package push is "forbidden" 170 | 171 | - Verify package ID ownership on NuGet.org 172 | - Check that the API key glob pattern includes your package name 173 | - Ensure you're the owner/co-owner of the package on NuGet.org 174 | 175 | ### GitVersion not working correctly 176 | 177 | - Ensure repository is cloned with full history (`fetch-depth: 0`) 178 | - Check `GitVersion.yml` configuration 179 | - Verify branch names match the patterns in `GitVersion.yml` 180 | 181 | ### Integration tests fail in CI 182 | 183 | - Check Neo4j service health in workflow logs 184 | - Verify connection string environment variables 185 | - Ensure sufficient wait time for Neo4j startup 186 | 187 | ## Next Steps 188 | 189 | After setting up secrets: 190 | 191 | 1. ✅ Push changes to trigger CI workflow 192 | 2. ✅ Verify CI workflow passes 193 | 3. ✅ Create a test tag to verify release workflow (optional) 194 | 4. ✅ Monitor first release to NuGet.org 195 | 5. ✅ Configure branch protection rules 196 | 197 | ## Support 198 | 199 | For issues with GitHub Actions or NuGet publishing, check: 200 | - [GitHub Actions

141 | 142 | ### 1. Configure GitHub Secrets 143 | 144 | **Required:** 145 | - `NUGET_API_KEY` - NuGet.org API key for publishing 146 | 147 | **Steps:** 148 | 1. Go to repository **Settings** → **Secrets and variables** → **Actions** 149 | 2. Click **New repository secret** 150 | 3. Name: `NUGET_API_KEY` 151 | 4. Value: Your NuGet.org API key 152 | 5. See `.github/SETUP.md` for detailed NuGet API key creation 153 | 154 | ### 2. Enable GitHub Actions 155 | 156 | Actions should be enabled by default, but verify: 157 | 1. Go to **Settings** → **Actions** → **General** 158 | 2. Ensure **Allow all actions and reusable workflows** is selected 159 | 160 | ### 3. Configure Branch Protection (Recommended) 161 | 162 | 1. Go to **Settings** → **Branches** 163 | 2. Add rule for `master`: 164 | - Require pull request reviews 165 | - Require status checks: `build-and-test` 166 | - Require branches to be up to date 167 | 3. Repeat for `develop` branch 168 | 169 | ### 4.
