Under the hood it uses Amazon's 8 | [aws-serverless-express][aws-s-e]. 9 | 10 | [ps-express]: https://github.com/nkly/purescript-express 11 | [aws-lambda]: https://aws.amazon.com/lambda 12 | [aws-s-e]: https://github.com/awslabs/aws-serverless-express 13 | 14 | 15 | ## Show me how it works 16 | 17 | ```sh 18 | bower install --save purescript-aws-lambda-express purescript-express 19 | npm install --save aws-serverless-express express 20 | ``` 21 | 22 | ```purescript 23 | module Main where 24 | 25 | import Node.Express.App (App, get) 26 | import Node.Express.Handler (Handler) 27 | import Node.Express.Response (sendJson) 28 | import Network.AWS.Lambda.Express as Lambda 29 | 30 | -- Define an Express web app 31 | 32 | indexHandler :: Handler 33 | indexHandler = do 34 | sendJson { status: "ok" } 35 | 36 | app :: App 37 | app = do 38 | get "/" indexHandler 39 | 40 | -- Define the AWS Lambda handler 41 | 42 | handler :: Lambda.HttpHandler 43 | handler = 44 | Lambda.makeHandler app 45 | ``` 46 | 47 | Now compile the application for use within Node JS, zip it up, and upload it 48 | to AWS Lambda specifying `Main.handler` as the handler string. 49 | 50 | FYI AWS Lambda really doesn't like directory names with `.`s in them and will 51 | throw a cryptic error, so best avoid a Purescript subdirectory. I lost an 52 | evening to this. 😓 53 | 54 | 55 | ## Why deploy a web app this way? 56 | 57 | - No infrastructure to manage or maintain. 58 | - Scaling takes seconds and handled automatically. 59 | - Pay per request, no money wasted on idle servers. 60 | - AWS's free quota is enough for low traffic apps. 61 | - Free monitoring and other goodies out the box. 62 | 63 | ## Why not? 64 | 65 | - Dedicated servers may be cheaper for high traffic apps. 66 | - With infrequent traffic [cold starts][cold-starts] can impact response time. 67 | - Compiling native extensions can be fiddly. 68 | - Any in-memory or on-filesystem state is ethereal and may be deleted between requests. 69 | 70 | [cold-starts]: https://aws.amazon.com/blogs/compute/container-reuse-in-lambda/ 71 | 72 | 73 | ## Is this ready for production? 74 | 75 | I've used AWS Lambda for production workloads since 2016. 76 | 77 | Or do you mean this library? Read the source, it's very small. 78 | 79 | 80 | ## What's the easiest way to deploy code to AWS Lambda? 81 | 82 | For automation of building zipping and uploading the application I have been 83 | using the [Serverless Framework][serverless-framework], which is friendlier 84 | than using the AWS API directly. This repository contains an example of it in 85 | use. See the `Makefile` and `test/Main.purs` for details. 86 | 87 | [serverless-framework]: https://serverless.com/framework 88 | 89 | 90 | ## LICENCE 91 | 92 | Copyright © 2017 - present Louis Pilfold.

Distribution of Source Form 163 | 164 | All distribution of Covered Software in Source Code Form, including any 165 | Modifications that You create or to which You contribute, must be under 166 | the terms of this License. You must inform recipients that the Source 167 | Code Form of the Covered Software is governed by the terms of this 168 | License, and how they can obtain a copy of this License. You may not 169 | attempt to alter or restrict the recipients' rights in the Source Code 170 | Form. 171 | 172 | 3.2. Distribution of Executable Form 173 | 174 | If You distribute Covered Software in Executable Form then: 175 | 176 | (a) such Covered Software must also be made available in Source Code 177 | Form, as described in Section 3.1, and You must inform recipients of 178 | the Executable Form how they can obtain a copy of such Source Code 179 | Form by reasonable means in a timely manner, at a charge no more 180 | than the cost of distribution to the recipient; and 181 | 182 | (b) You may distribute such Executable Form under the terms of this 183 | License, or sublicense it under different terms, provided that the 184 | license for the Executable Form does not attempt to limit or alter 185 | the recipients' rights in the Source Code Form under this License. 186 | 187 | 3.3. Distribution of a Larger Work 188 | 189 | You may create and distribute a Larger Work under terms of Your choice, 190 | provided that You also comply with the requirements of this License for 191 | the Covered Software. If the Larger Work is a combination of Covered 192 | Software with a work governed by one or more Secondary Licenses, and the 193 | Covered Software is not Incompatible With Secondary Licenses, this 194 | License permits You to additionally distribute such Covered Software 195 | under the terms of such Secondary License(s), so that the recipient of 196 | the Larger Work may, at their option, further distribute the Covered 197 | Software under the terms of either this License or such Secondary 198 | License(s). 199 | 200 | 3.4. Notices 201 | 202 | You may not remove or alter the substance of any license notices 203 | (including copyright notices, patent notices, disclaimers of warranty, 204 | or limitations of liability) contained within the Source Code Form of 205 | the Covered Software, except that You may alter any license notices to 206 | the extent required to remedy known factual inaccuracies. 207 | 208 | 3.5. Application of Additional Terms 209 | 210 | You may choose to offer, and to charge a fee for, warranty, support, 211 | indemnity or liability obligations to one or more recipients of Covered 212 | Software. However, You may do so only on Your own behalf, and not on 213 | behalf of any Contributor. You must make it absolutely clear that any 214 | such warranty, support, indemnity, or liability obligation is offered by 215 | You alone, and You hereby agree to indemnify every Contributor for any 216 | liability incurred by such Contributor as a result of warranty, support, 217 | indemnity or liability terms You offer. You may include additional 218 | disclaimers of warranty and limitations of liability specific to any 219 | jurisdiction. 220 | 221 | 4. Inability to Comply Due to Statute or Regulation 222 | --------------------------------------------------- 223 | 224 | If it is impossible for You to comply with any of the terms of this 225 | License with respect to some or all of the Covered Software due to 226 | statute, judicial order, or regulation then You must: (a) comply with 227 | the terms of this License to the maximum extent possible; and (b) 228 | describe the limitations and the code they affect. Such description must 229 | be placed in a text file included with all distributions of the Covered 230 | Software under this License.

Termination 235 | -------------- 236 | 237 | 5.1. The rights granted under this License will terminate automatically 238 | if You fail to comply with any of its terms. However, if You become 239 | compliant, then the rights granted under this License from a particular 240 | Contributor are reinstated (a) provisionally, unless and until such 241 | Contributor explicitly and finally terminates Your grants, and (b) on an 242 | ongoing basis, if such Contributor fails to notify You of the 243 | non-compliance by some reasonable means prior to 60 days after You have 244 | come back into compliance. Moreover, Your grants from a particular 245 | Contributor are reinstated on an ongoing basis if such Contributor 246 | notifies You of the non-compliance by some reasonable means, this is the 247 | first time You have received notice of non-compliance with this License 248 | from such Contributor, and You become compliant prior to 30 days after 249 | Your receipt of the notice. 250 | 251 | 5.2. If You initiate litigation against any entity by asserting a patent 252 | infringement claim (excluding declaratory judgment actions, 253 | counter-claims, and cross-claims) alleging that a Contributor Version 254 | directly or indirectly infringes any patent, then the rights granted to 255 | You by any and all Contributors for the Covered Software under Section 256 | 2.1 of this License shall terminate. 257 | 258 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all 259 | end user license agreements (excluding distributors and resellers) which 260 | have been validly granted by You or Your distributors under this License 261 | prior to termination shall survive termination. 262 | 263 | ************************************************************************ 264 | * * 265 | * 6.
