Benchmarks

All benchmarks run using Node v14.15.3

Load Time

Measures how long it takes to require a library.

pug:         127.647ms
ejs:           1.444ms
handlebars:   23.627ms
yeahjs:        0.979ms
dot:           1.363ms
art-template:  8.847ms
tempura:       0.593ms

Compile Time

How quickly a template is parsed and generated into a function equivalent.

Results display the average of 5 runs, in milliseconds.

Important: All candidates use a different template syntax.

Render - Raw Values

Measures how quickly the generated functions render an output string.

Note: All candidates do not escape template values - hence "raw" values.

All candidates produce the same output value, which is used as a validation step.

Benchmark (Render)
  pug                x 34,847 ops/sec ±2.79% (93 runs sampled)
  handlebars         x  6,700 ops/sec ±1.41% (92 runs sampled)
  ejs                x    802 ops/sec ±0.54% (94 runs sampled)
  yeahjs             x 31,508 ops/sec ±0.30% (97 runs sampled)
  dot                x 40,704 ops/sec ±3.08% (93 runs sampled)
  art-template       x 39,839 ops/sec ±0.86% (90 runs sampled)
  tempura            x 44,656 ops/sec ±0.42% (92 runs sampled)

Render – Escaped Values

Measures how quickly the generated functions render an output string. All template values are escaped, unlike the Raw Values benchmark above.

Important: All candidates use a different escape() sequence.

Benchmark (Render)
  pug                x 2,800 ops/sec ±0.31% (95 runs sampled)
  handlebars         x   733 ops/sec ±0.34% (94 runs sampled)
  ejs                x   376 ops/sec ±0.17% (91 runs sampled)
  yeahjs             x   873 ops/sec ±0.30% (95 runs sampled)
  dot                x   707 ops/sec ±0.15% (96 runs sampled)
  art-template       x 2,707 ops/sec ±0.12% (96 runs sampled)
  tempura            x 2,922 ops/sec ±0.31% (96 runs sampled)
