Strapi-common-api NPM

strapi-common-api

provide a "strapi client SDK" wrapped some common request api service functions and strapi types support for strapi based frontend apps, and provide some key typescript types hint help, which is something that is not yet officially implemented by strapi[1] [2]

populate_deep

data types were generated by types-4-strapi, but some types need some manual correction, like "createdAt", "updatedAt", etc..

install

npm install strapi-common-api axios qs -s

yarn add strapi-common-api axios qs

usage - strapi-client

you can create your customized strapi client like this, the key types were wrapped in functions below, declare the type of the entity generated by types-4-strapi to get the correct type prompt information

import {createStrapiClient} from "strapi-common-api";
import {Post} from "./Post";

const {
    strapiClient,
    collection,
    single,
    auth
} = createStrapiClient("http://localhost:1337/api", {/* some axios config */})

// customize your client
strapiClient.interceptors.request.use(config => config)

collection.getMany<Post>('posts', {
    populate: ["comments"],
    fields: ["user", "content"]
})

usage - functions

besides strapi client, you can also use these function directly like this.

but at first remember to override strapi request instance, which based on axios module, you can customize your interceptors (such as add jwt token before request) or some other params (such as base url)

import {auth, collection, single, strapiRequest} from "strapi-common-api"
import {Post} from "./Post";
import {Global} from "./Global";

// override your strapi api url like this
strapiRequest.defaults.baseURL = "http://localhost:1337/api"// defalut base url value

// here your editor will give you some hints on params and return data
auth.login({identifier, password})
    .then(({user, jwt}) => {
        // do something ...
    })

collection.getMany<Post>("posts", {
    filters: {
        title: {
            $eq: "test"
        }
    },
    populate: {// support multi-level populate
        user: {
            populate: ["avatar"]
        }
    }
}).then(({data, meta}) => {
    // do something ...
})

single.get<Global>("global").then(r => {
    // do something ...
})

usage - types

your IDE will give some hints when coding objects of these types, like this

err... there are too many types exported, here only introduce some key types

Populate

strapi populate object type

import {Populate} from "strapi-common-api";
import {Post} from "./Post";

type P = Populate<Post>

// common populate
const p1: P = "deep"
const p2: P = ["deep", 10]
const p3: P = 10
const p4: P = "*"
const p5: P = ["user", "comments"]
const p6: P = {
    // multi level populate
    user: {
        populate: "*"
    },
    comments: {
        populate: ["user", "post", "comment_votes"]
    },

    // deep populate
    post_likes: {
        populate: {
            user: {
                populate: "*"
            }
        }
    }
}
const p7: P = {
    comments: "*",
    post_votes: "*",
    user: "*",
    post_likes: {
        populate: ["user"]
    }
}

Filters

strapi filters object type

import {Filters} from "strapi-common-api";
import {Post} from "./Post";

type F = Filters<Post>

const f1: F = {
    // common field
    content: {
        $contains: "haha"
    },

    // relation field
    user: {
        username: {
            $eq: "littlebadbad",
            $null: true,
            $containsi: "little",
            $startsWith: "l"
        }
    },

    // array relation field
    comments: {
        content: {
            $startsWith: "haha"
        },
        user: {
            username: {
                $startsWith: "l"
            }
        }
    },

    // logical operator filter
    $and: [
        {content: {$contains: "hello"}},
        {title: {$contains: "hi"}}
    ],
    $not: {
        user: {
            username: {
                $startsWith: "a"
            }
        }
    }
}

Sort

strapi sort object type

import {Sort} from "strapi-common-api";
import {Post} from "./Post";

type S = Sort<Post>

const s1: S = "content"
const s2: S = ["content", "id"]
const s3: S = {
    content: "DESC",
    title: "ASC"
}
const s4: S = [
    {
        content: "DESC"
    },
    {
        title: "ASC"
    }
]

Query

query object followed by each strapi url, use qs library to stringify it, schema of query object follows the strapi api parameters

includes: locale, filters, publicationState, pagination, sort, fields, populate

// Post type was generated by types-4-strapi
import {Post} from "./Post";
import {Query, Payload} from "strapi-common-api"

export function getPosts(query?: Query<Post>): Promise<Payload<Post[]>> {
    return strapiRequest.get(`/posts?${qs.stringify(query, {encodeValuesOnly: true})}`)
        .then(r => r.data)
}

// here your editor will give you some type hints
getPosts({
    filters: {
        title: {$contains: "test"}
    },
    populate: ["user"],
    sort: ["updatedAt"]
})
