  • register
yiigo.Init(
    yiigo.WithDB(yiigo.Default, yiigo.MySQL, "dsn", options...),
    yiigo.WithDB("other", yiigo.MySQL, "dsn", options...),
)
  • sqlx
// default db
yiigo.DB().Get(&User{}, "SELECT * FROM user WHERE id = ?", 1)

// other db
yiigo.DB("other").Get(&User{}, "SELECT * FROM user WHERE id = ?", 1)
  • ent
import "<your_project>/ent"

// default driver

MongoDB

// register
yiigo.Init(
    yiigo.WithMongo(yiigo.Default, "dsn"),
    yiigo.WithMongo("other", "dsn"),
)

// default mongodb
yiigo.Mongo().Database("test").Collection("numbers").InsertOne(context.Background(), bson.M{"name": "pi", "value": 3.14159})

// other mongodb
yiigo.Mongo("other").Database("test").Collection("numbers").InsertOne(context.Background(), bson.M{"name": "pi", "value": 3.14159})

Redis

// register
yiigo.Init(
    yiigo.WithRedis(yiigo.Default, "address", options...),
    yiigo.WithRedis("other", "address", options...),
)

// default redis
conn, err := yiigo.Redis().Get(context.Background())

if err != nil {
    log.Fatal(err)
}

defer yiigo.Redis().Put(conn)

conn.Do("SET", "test_key", "hello world")

// other redis

// other logger
yiigo.Logger("other").Info("hello world")

gRPC Pool

// create pool
pool := yiigo.NewGRPCPool(
    func() (*grpc.ClientConn, error) {
        return grpc.DialContext(context.Background(), "target",
            grpc.WithInsecure(),
            grpc.WithBlock(),
            grpc.WithKeepaliveParams(keepalive.ClientParameters{
                Time:    time.Second * 30,
                Timeout: time.Second * 10,
            }),
        )
    },
    yiigo.WithPoolSize(10),
    yiigo.WithPoolLimit(20),
    yiigo.WithPoolIdleTimeout(600*time.Second),
)

// use pool
conn, err := pool.Get(context.Background())

if err != nil {
    return err
}

defer pool.Put(conn)

// coding...

HTTP

// default client
ctx, _ := context.WithTimeout(context.Background(), 5*time.Second)
yiigo.HTTPGet(ctx, "URL")

// new client
client := yiigo.NewHTTPClient(*http.Client)

ctx, _ := context.WithTimeout(context.Background(), 5*time.Second)
client.Do(ctx, http.MethodGet, "URL", nil)

SQL Builder

😊 为不想手写SQL的你生成SQL语句，用于 sqlx 的相关方法；

⚠️ 作为辅助方法，目前支持的特性有限，复杂的SQL（如：子查询等）还需自己手写

builder := yiigo.NewSQLBuilder(yiigo.MySQL)
  • Query
builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("id = ?", 1),
).ToQuery()
// SELECT * FROM user WHERE id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("name = ? AND age > ?", "shenghui0779", 20),
).ToQuery()
// SELECT * FROM user WHERE name = ? AND age > ?
// [shenghui0779 20]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.WhereIn("age IN (?)", []int{20, 30}),
).ToQuery()
// SELECT * FROM user WHERE age IN (?, ?)
// [20 30]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Select("id", "name", "age"),
    yiigo.Where("id = ?", 1),
).ToQuery()
// SELECT id, name, age FROM user WHERE id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Distinct("name"),
    yiigo.Where("id = ?", 1),
).ToQuery()
// SELECT DISTINCT name FROM user WHERE id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.LeftJoin("address", "user.id = address.user_id"),
    yiigo.Where("user.id = ?", 1),
).ToQuery()
// SELECT * FROM user LEFT JOIN address ON user.id = address.user_id WHERE user.id = ?
// [1]

builder.Wrap(
    yiigo.Table("address"),
    yiigo.Select("user_id", "COUNT(*) AS total"),
    yiigo.GroupBy("user_id"),
    yiigo.Having("user_id = ?", 1),
).ToQuery()
// SELECT user_id, COUNT(*) AS total FROM address GROUP BY user_id HAVING user_id = ?
// [1]

builder.Wrap(
    yiigo.Table("user"),
    yiigo.Where("age > ?", 20),
    yiigo.OrderBy("age ASC", "id DESC"),
    yiigo.Offset(5),
    yiigo.Limit(10),
).ToQuery()
// SELECT * FROM user WHERE age > ? ORDER BY age ASC, id DESC LIMIT ? OFFSET ?
// [20, 10, 5]

wrap1 := builder.Wrap(
    Table("user_1"),
    Where("id = ?", 2),
)

builder.Wrap(
    Table("user_0"),
    Where("id = ?", 1),
    Union(wrap1),
).ToQuery()
// (SELECT * FROM user_0 WHERE id = ?) UNION (SELECT * FROM user_1 WHERE id = ?)
// [1, 2]

builder.Wrap(
    Table("user_0"),
    Where("id = ?", 1),
    UnionAll(wrap1),
).ToQuery()
// (SELECT * FROM user_0 WHERE id = ?) UNION ALL (SELECT * FROM user_1 WHERE id = ?)
// [1, 2]

builder.Wrap(
    Table("user_0"),
    WhereIn("age IN (?)", []int{10, 20}),
    Limit(5),
    Union(
        builder.Wrap(

            Where("age IN (?)", []int{30, 40}),

).ToQuery()
// (SELECT * FROM user_0 WHERE age IN (?, ?) LIMIT ?) UNION (SELECT * FROM user_1 WHERE age IN (?, ?) LIMIT ?)
// [10, 20, 5, 30, 40, 5]

builder.Wrap(Table("user")).ToTruncate()
// TRUNCATE user

  • Update

  • Delete
