4 | 5 | # Deploying Serverless NestJS GraphQL API to Azure Functions 6 | 7 | Getting `nest/azure-func-http` and `nest/graphql` to play well together is tricky. There are several GH issues and SO posts on this topic with little in the way of a solution. Additionally, none of the official nest.js docs or samples contain a configuration with both graphql and azure functions. 8 | 9 | The one source of reliable information on this topic is a blog post by trilon.io [here](https://trilon.io/blog/deploy-nestjs-azure-functions). This is a good tutorial on creating a Nest.js REST api with `nest/azure-func-http`. However the tutorial steps to not carry over directly when creating a GraphQl API. 10 | 11 | This repo and tutorial is a minimal example of a working integration of `nest/azure-func-http` and `nest/graphql`. I hope this helps some folks out! 12 | 13 | ## Starting Point 14 | 15 | I started this repo with the boilerplate from [23-type-graphql](https://github.com/nestjs/nest/tree/master/sample/23-type-graphql). This is a working repo with Typescript, GraphQL, and Nest but NOT `nest/azure-func-http` 16 | 17 | ## Adding azure-func-http 18 | 19 | ```bash 20 | $ nest add @nestjs/azure-func-http 21 | ``` 22 | 23 | This will install the function app boilerplate in the repo. Here is where this tutorial deviates from the trilion.io tutorial. Several of the default azure function configurations need to be altered along with some of your nest app code. 24 | 25 | ## Steps 26 | 27 | ### 1. Change build script in `package.json` 28 | 29 | ```diff 30 | - "build": "nest build" 31 | + "build": "rimraf dist && tsc -p tsconfig.build.json" 32 | ``` 33 | 34 | ### 2. Remove the include from your tsconfig.json 35 | 36 | ```diff 37 | { 38 | "compilerOptions": { 39 | "module": "commonjs", 40 | "declaration": true, 41 | "removeComments": true, 42 | "allowSyntheticDefaultImports": true, 43 | "emitDecoratorMetadata": true, 44 | "experimentalDecorators": true, 45 | "target": "es2017", 46 | "sourceMap": true, 47 | "outDir": "./dist", 48 | "baseUrl": "./", 49 | "incremental": true, 50 | "skipLibCheck": true 51 | }, 52 | - "include": ["src/**/*"], 53 | "exclude": ["node_modules", "dist"] 54 | } 55 | ``` 56 | 57 | These two steps create seperate `/src` and `/main` directories in `/dist`. 58 | 59 | - `/src` is for your source code 60 | - `/main` is the entry point for the function app 61 | 62 | ### 3. Adjust Nest.js App 63 | 64 | At this point the azure function will run but it will not resolve your GraphQL requests! Some changes need to be made to the nest app itself. 65 | 66 | main.ts 67 | 68 | ```diff 69 | import { ValidationPipe } from "@nestjs/common"; 70 | import { NestFactory } from "@nestjs/core"; 71 | import { AppModule } from "./app.module"; 72 | 73 | async function bootstrap() { 74 | const app = await NestFactory.create(AppModule); 75 | app.useGlobalPipes(new ValidationPipe()); 76 | + app.enableCors(); 77 | + app.setGlobalPrefix("api"); 78 | await app.listen(3000); 79 | } 80 | bootstrap(); 81 | ``` 82 | 83 | app.module.ts 84 | 85 | ```diff 86 | import { Module } from "@nestjs/common"; 87 | import { GraphQLModule } from "@nestjs/graphql"; 88 | import { RecipesModule } from "./recipes/recipes.module"; 89 | 90 | @Module({ 91 | imports: [ 92 | RecipesModule, 93 | GraphQLModule.forRoot({ 94 | installSubscriptionHandlers: true, 95 | + context: ({ req }) => ({ req }), 96 | autoSchemaFile: "schema.gql", 97 | + useGlobalPrefix: true 98 | }) 99 | ] 100 | }) 101 | export class AppModule {} 102 | ``` 103 | 104 | 3. Adjust function app config 105 | 106 | host.json 107 | 108 | ```diff 109 | { 110 | "version": "2.0", 111 | + "extensions": { 112 | + "http": { 113 | + "routePrefix": "api" 114 | + } 115 | } 116 | } 117 | ``` 118 | 119 | index.ts 120 | 121 | ```diff 122 | import { Context, HttpRequest } from "@azure/functions"; 123 | import { AzureHttpAdapter } from "@nestjs/azure-func-http"; 124 | import { createApp } from "../src/main.azure"; 125 | 126 | export default function(context: Context, req: HttpRequest): void { 127 | + context.res = { 128 | + headers: { 129 | + "Content-Type": "application/json" 130 | + } 131 | + }; 132 | AzureHttpAdapter.handle(createApp, context, req); 133 | } 134 | 135 | ``` 136 | 137 | ### Your GraphQL function app is good to go!! 138 | 139 | ```bash 140 | $ npm run build && func host start 141 | ``` 142 | 143 | ### Testing out the app 144 | 145 | Add a sample body to the create method in `recipies.service.ts` for testing. 146 | 147 | recipies.service.ts 148 | 149 | ```diff 150 | async create(data: NewRecipeInput): Promise { 151 | + return { 152 | + id: "sample", 153 | + title: data.title, 154 | + description: data.description, 155 | + creationDate: new Date(), 156 | + ingredients: data.ingredients 157 | + } as Recipe; 158 | - return {} as any; 159 | } 160 | ``` 161 | 162 | fire up http://localhost:7071/api/graphql and run a mutation 163 | 164 | ```graphql 165 | mutation($newRecipeData: NewRecipeInput!) { 166 | addRecipe(newRecipeData: $newRecipeData) { 167 | creationDate 168 | } 169 | } 170 | ``` 171 | 172 | query variables 173 | 174 | ```json 175 | { 176 | "newRecipeData": { 177 | "title": "Salad", 178 | "description": "Im trying to be healthy and im disappointed in my self", 179 | "ingredients": ["leaves", "sadness"] 180 | } 181 | } 182 | ``` 183 | 184 | you should get back something like.... 185 | 186 | ```json 187 | { 188 | "data": { 189 | "addRecipe": { 190 | "creationDate": 1582340836192 191 | } 192 | } 193 | } 194 | ``` 195 | 196 | --- 197 | 198 | ## Deploying to Azure Functions 199 | 200 | > _The battle has been won but the war has just begun_ 201 | 202 | 203 | 1. Create resource in Azure Portal 204 | 205 | Navigate to your azure account and create a new `Function App`. The `Create Function App` workflow contains five tabs: Basics, Hosting, Monitoring, Tags, and Review + create. Settings in `Basics` and `Hosting` need to be adjusted, the other tabs can be left at their defaults. 206 | 207 | > Basics 208 | 209 | ![Basics](https://m0ss.blob.core.windows.net/media/create1.png) 210 | 211 | > Hosting 212 | 213 | ![Hosting](https://m0ss.blob.core.windows.net/media/create2.png) 214 | 215 | 216 | Upon completing the Basics and Hosting, press `Review + create` to deploy the function app. 217 | 218 | 219 | 2. Deploy your code to the Function App 220 | 221 | Once created, head back to your editor and deploy your Nest Graphql App to this newly created Function App. 222 | 223 | ```bash 224 | $ npm run build && func azure functionapp publish 225 | ``` 226 | 227 | This will create an output similar to the following: 228 | 229 | ![Deploy](https://m0ss.blob.core.windows.net/media/deploy.png) 230 | 231 | **Note**: This step requires `Azure Functions Core Tools v3` for local development and deployment of Azure Functions. Instructions on how to get this on your development machine can be found [here](https://github.com/Azure/azure-functions-core-tools) 232 | 233 | 3. Use the deployed graphql endpoint 234 | 235 | Wait a few minutes for the application to propagate then head to the deployed graphql endpoint: `https://.azurewebsites.net/api/graphql` 236 | 237 | You should then be treated to the graphql playground. 238 | 239 | ![Playground](https://m0ss.blob.core.windows.net/media/playground.png) 240 | 241 | 242 | ## Notes on Deployment 243 | 244 | Getting the function to run remotely on azure is not clear cut. I have found that the best configuration options are Function app V3 and WEBSITES_NODE_DEFAULT_VERSION set to ~12 245 | 246 | Documentation on how to changes these Azure related setting can be found [here](https://docs.microsoft.com/en-us/azure/azure-functions/) 247 | 248 | If you are using vscode there is some helpful extensions for deploying function apps. Your can read about that [here](https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first-function-vs-code?pivots=programming-language-typescript) 249 | 250 | Included in this repo is a `template.zip`.
