⚡️Thunderlight is the fastest Python HTTP Server

Thunderlight is the fastest Python HTTP Server. It's dedicated for micro service and JSON API. In the future, a C version of this API is also supported. You can write Python or C in your server project to speed things up.

Installation

Install Thunderlight with pip.

pip install thunderlight

Documentation

get

Register a get request handler to the default app.

@get('/posts/:id')
async def posts(ctx: Ctx) -> None:
    ctx.res.json((await Post.id(ctx.req.args.id)).tojson())

post

Register a post request handler to the default app.

@post('/posts')
async def posts(ctx: Ctx) -> None:
    ctx.res.json(Post(**(await ctx.req.json())).save().tojson())

patch

Register a patch request handler to the default app.

@patch('/posts/:id')
async def posts(ctx: Ctx) -> None:
    ctx.res.json((await Post.id(ctx.req.args.id)).set(await ctx.req.json()).save().tojson())

delete

Register a delete request handler to the default app.

@delete('/posts/:id')
async def posts(ctx: Ctx) -> None:
    ctx.res.empty((await Post.id(ctx.req.args.id)).delete())

use

Append this middleware to the default app's middleware stack.

@use
async def measure_time(ctx: Ctx, next: Next) -> None:
    start = time()
    await next(ctx)
    time_elapsed = time() - start
    print(f'request {ctx.req.path} takes {time_elapsed} second.')

apply

Apply a middleware to a request handler. This is aka middleware for a single request handler.

async def validate_user(ctx: Ctx, next: Next) -> None:
    if ctx.req.headers['Authorization'] is not None:
        await next(ctx)
    else:
        ctx.res.code = 401
        ctx.res.json({"error": {"type": "Unauthorized"}})


@get('/users')
@apply(validate_user)
async def users(ctx: Ctx) -> None:
    ctx.res.json(await User.find())

App

Create a new server application.

app = App()

@app.get('/articles')
async def articles(ctx: Ctx) -> None:
    ctx.res.json(await Article.find())

Ctx

The context represents a request session.

ctx.req

The request object. This object is readonly.

ctx.res

The response object. Modify this object to present data to the user.

ctx.state

The custom state object that is internal to your custom handling code.

Req

This class represents the incoming request. This object is readonly.

req.client

The request client.

req.scheme

The request HTTP scheme.

req.version

The request HTTP version.

req.method

The request HTTP method.

req.path

The path of the request URL.

req.args

The args matched from url routing.

req.qs

The query string of the request URL.

req.headers

The request headers.

await req.body()

The raw request body.

await req.json()

The request's json body.

await req.form()

The request's form body.

await req.dict()

The request's json body or form body.

Res

The class represents the response returned to the frontend.

res.code

The status code.

res.headers

The response headers.

res.body

The response body.

res.json()

Response json to the frontend.

res.text()

Response text to the frontend

res.html()

Response html text to the frontend

res.redirect()

Response a redirect request to the frontend

res.file()

Response a file to the frontend

res.empty()

Empty response

State

You can attach anything to the state and fetch by key. This state shares the same state across middlewares and the route handler.

@app.get('/articles')
async def articles(ctx: Ctx) -> None:
    ctx.state.user = custom_user
    ctx.state.user # custom_user
