We are considering moving away from Joi for validation of request bodies on our API endpoints. In the process we are evaluating class-validator as an alternative; this project aims to uncover performance differences between the two approaches.
git clone https://github.com/srindom/medusa-validation-benchmarks.git
cd medusa-validation-benchmarks
yarn && yarn benchmark
100000 dummy request payloads for Order Filters have been generated. The project runs validation on all of them in sequence using Joi's validate function and class-validator's validateSync function.
The timing was performed over 10 runs and the results show the average time for a run.
- class-validator + class-transformer: takes on avg 1115.3
- Joi validation: takes on avg 1369.9
$ yarn benchmark
yarn run v1.22.11
$ ts-node ./src/benchmark.ts
class-validator avg: 1115.3
joi avg: 1369.9
✨ Done in 25.85s.
- class-validator + class-transformer: takes on avg 2668.6
- Joi validation: takes on avg 3055.2
$ yarn benchmark
yarn run v1.22.10
$ ts-node ./src/benchmark.ts
class-validator avg: 2668.6
joi avg: 3055.2
✨ Done in 59.22s.
- class-validator + class-transformer: takes on avg 2992.9
- Joi validation: takes on avg 3515.2
$ yarn benchmark
yarn run v1.22.5
$ ts-node ./src/benchmark.ts
class-validator avg: 2992.9
joi avg: 3515.2
Done in 67.47s.
class-validator + class-transformer is clearly the fastest option.
